MB Sturgis Propane Fittings - 103539-MBS
- Adapter Fittings
- POL - Female
- 1/4 Inch - Male QD
- MB Sturgis
Hook up an auxiliary tank to your RV to provide propane in case your primary runs dry during long campouts and get extra versatility in your propane system. Gives you a quick-disconnect outlet for cooking and includes supply hose and extension hose.
Features:
- T-fitting kit lets you connect a backup auxiliary cylinder to your RV's propane system
- No need to break up camp to go refill your onboard ASME tank
- POL fittings install in-line between your tank valve and pigtail to your pressure regulator
- 2 Model 250 quick-disconnect ports let you hook up and disconnect without hand tightening
- When valve on your ASME tank is closed, one port can function as an inlet for an auxiliary tank
- When valve on your tank is open, can provide propane to 2 appliances
- Shut-off levers on quick-disconnect ports allow you to easily shut off gas supply
- Ball valve prevents disconnection when lever is in the "on" position to keep gas contained
- Supply hose with male quick-disconnect and male POL fittings is included to attach auxiliary tank
- Close valve on your RV's primary tank, attach POL to backup tank, and attach to Sturgi-Stay
- Designed for high-pressure and high flow without going into bypass mode
- Adapter hose with #600 (1"-20) to quick-disconnect fittings included to fuel your portable camping grill
- Eliminates need for wasteful disposable cylinders that quickly run out of gas
- Durable brass fittings approved for LP gas only
- UL and CSA certified
- Made in the USA
Specs:
- Temperature range: -40 F to 350 F
- Maximum pressure rating: 250 psi
- Supply hose dimensions: 72" long x 1/4" inner diameter
- Supply hose fittings:
- 1/4" Male Model 250 quick-disconnect
- POL tank connection
- Adapter hose dimensions: 120" long x 1/4" inner diameter
- Adapter hose fittings:
- Male #600 (1"-20)
- 1/4" Male Model 250 quick-disconnect

Note: When using quick-disconnect ports for cooking, bear in mind that the propane pressure is still high, as the Sturgi-Stay is installed before the regulator. Outdoor cooktops, grills, or other appliances will often require a regulator. Check your equipment to see if one is required.
Make camping more fun and relaxing. Moving your RV once you've gotten settled at the campsite is a real chore. No one wants to have to pack up, unplug, and go refill the propane tank, just to come back to the site and set everything up all over again. This Sturgi-Stay T-fitting lets you connect an auxiliary cylinder to your setup using the included fill hose. As a result, you can run your appliances from the propane in your cylinder rather than using up the LP gas from your RV's tank. When you run out, just refill the auxiliary cylinder and hook it up again.
Quick Disconnect Ports
The Sturgi-Stay features 2 quick-disconnect ports. The first port connects to the included fill hose from the auxiliary cylinder. The other port provides a connection point for a small, portable appliance or propane tree, via the included adapter hose. This way you can power a grill, heater, or other accessory without needing to use a 1-lb throwaway cylinder.
Both quick-disconnect ports let you connect and disconnect the included hoses without any tools. Simply snap the quick-disconnect hoses into the ports and they will stay locked in until you release them. To remove the hoses, just pull back on the collars of the ports. The ports also feature gas shut-off levers that allow you to completely cut off the propane supply to that port to keep gas contained when no hose is attached. Be sure to move the lever to the "off" position before disconnecting the hose.

Just what I needed to connect a spare 20 lbs propane cylinder in line with the rv onboard tank. Now I can use the onboard tank as a backup and just refill the 20 pounder. 5 minute job to install and do a soap test for leaks. Can also hook our portable grill up to the 2nd quick connect. Perfect!

The total package, far better than others on the market. Includes the 2 hoses needed, 1 for your grill, 1 for your portable tank. A quality fitting that includes a quarter turn shutoff and quick couple on each branch. Shutoff relieves the pressure for connecting hoses and when the valve is then opened, it locks the coupler. Easy installation, I added a 4”x4” piece of plate steel to extend the mounting surface for the plastic regulator housing to attach to. This should help to reduce any strain the fittings. I had an issue with one of the included hoses. It appeared to be a defective nipple on one end that kept it from slipping into the coupler. One quick email and I had a replacement in just a couple days. “Thanks Carol and Hanna, you guys are great”

one of the best products I have purchased for my RV. Using it now, as I write, Allowing my main tank to be shut off, instead relying upon a small portable tank that can be exchanged nearly everywhere....2nd hose allows for any propane item that has its on regular to be attached to the RV' main tank or the portable as it is being used of other purposes....And my RV has a measured "after the standard regulator" port for a BAR B Q pit that came with the RV....and I still find great value with the accessory I purchased that had\s 2 ports and hoses!

As always fast service, items arrived as promised. Especially thankful this time for the ability to purchase a single replacement snap pad. Despite the manufacturers promise that they never fall off we lost one on our last 2500 mile trip where we stayed on level pads in commercial campgrounds. We think it might have been a manufacturing flaw since the other three are in place and firm, but with the pad lost we really don't know what the root cause was. Irritating was that Amazon and their supplier did not understand the problem and wanted us to return the "complete" item and they were not able to sell us a replacement pad and offered us a 20$ refund. etrailer to the rescue. Thanks. We will make sure that we look at etrailer first in the future.

still working great, staying put. We have used the rig on a 2 week trip and used the jacks on gravel, dirt and blacktop. No problems with the pads whatsoever and very convenient not having to crawl under the rig to place regular pads. This is a great product and we probably got a bad pad in the first delivery. The first seller just did not have the customer service. Good product, bad seller still equals to bad experience. Thanks again to eTrailer and their more than stellar customer service. Be aware that when you buy from Amazon, most likely they have no clue what they are selling and when you have a problem you are on your own. Thanks etrailer!!!

This Kit was a breeze to install. Standard propane fittings.
On my Class C motor home I had to extend the guard plate to protect the regulator since the kit move it out further and exposed to road debris.
Now if I get low/run out of propane, I can just connect 20/30 pound cylinders with the quick connects.

I have had this for a year now and it is one of the best modifications I have made to my motor home. I no longer need to take a 41' motor home down to get propane, I can now just use 20lbs tanks instead. The quick disconnects makes this very easy to use.

the hardware fittings worked fine; the hose for some reason would not allow adequate flow of propane to the regulated appliance. I purchased another hose and it works now.

I hate when that happens. I just wanted to make sure you are not running the propane through 2 regulators. You do not want your propane to be double regulated because it is going to cause you to not have enough gas pressure for your appliances to work properly. Basically if the appliance you are using the T-fitting to run to has its own built in regulatorwhich is common, you will want the T-fitting prior to the regulator.

Probably the easiest upgrade I've ever made. Took about 10 minutes. Start to finish. Having flexibility about where to buy propane being able to fill portable bottles instead of needing pay direct hookup to the tank, is going to make cold weather traveling infinitely easier.

The MB Sturgis parts worked exactly as advertised. As info, the propane tank compartment in our 1985 Coachmen is very tight, so we did need to replace pipes, fittings, and hoses to make it fit.

This very cool device is going to be used on a 2021 Integra odyssey 24 B motorhome. My wife and I are very familiar with going to the state parks in North Carolina, and by the way we have some excellent state parks in North Carolina, but we’re exploring the possibility of doing more Boondocking. I believe this device will come in very handy on those days when a little extra gas might be needed. I am impressed with the fact that this kit comes with everything you need to install it in your main gas line, hook up an outside propane cylinder for additional fuel, and allows you a hose so that certain gas operated heating devices can be attached to the system directly. Ordering was easy and shipping was prompt. Couldn’t ask for more. Well done.

I am very happy with this kit. Our motor home has a permanently mounted propane tank. This kit allows me to connect a portable propane cylinder to my motor home. We will be staying at a ranch for the next several months. They supply 100 lb. cylinders. This saves me from having to move the whole house every time I need to refill the propane tank. Installation was simple.

We needed a way to use a portable propane tank with our motorhome so we didn’t have to break down and move when we ran out of the onboard tank. Bought one but the fittings were right. This one works with what was on our 1999 Winnebago Brave. The short hose will connect to our portable tank but the longer hose fittings will not work with our grill or stove, so that part is a waste. However the quick connect fittings are a nice feature.

The MB Sturgis Sturgi-Stay T-Fitting w/ Hoses item # 103539-MBS has a POL Valve as shown in the pictures below.

This will allow you to connect the red fitting to one of your tanks and the pigtail from that tank to the brass side of the T-fitting.

view full answer... - Parts Needed to Add 100 lb Propane Tank Setup to RV We have kits that are designed for connecting an auxiliary tank to a propane setup on a fifth wheel like yours but we don't recommend trying to fill up what you have now with a 100 lb tank. What you'd need is the MB Sturgis Sturgi-Stay T-Fitting w/ Hoses for POL Valve # 103539-MBS.

view full answer... - Can I Connect A Portable Grill To The Propane Manifold On My 19 KZ Connect C303RLHello John, thanks for reaching out. Portable grills are intended to be used with their own propane tank, so there is no way to connect a grill to the manifold on your RV. The propane coming from your RV is already regulated, and the grill has its own built-in regulator. So this would double regulate the propane which will not allow the grill to work properly. Your best option for this will be to carry a separate propane tank for the grill. If space is tight, you can always use a small...

It sounds like you have an unusual setup because to my knowledge all 100 lb motorhome propane tanks use the POL port like what came on the MB Sturgis Sturgi-Stay T-Fitting w/ Hoses # 103539-MBS you got from us. With that being said, if you're needing the Propane Adapter Fitting # 37207-30095 then this takes a 1/4" Male NPT fitting and changes it to a POL fitting that your MB Sturgis T-Fitting is compatible with.

Typically if you're routing permanent lines it's recommended to use a copper hard line instead of a hose so you would need a tee like # 37207-30135 to be able to connect the line.

The first is a pressure gauge like the Camco # CAM59023. This reads the pressure of vapor propane which remains steady until mostly empty then the needle moves quickly to empty. However, Camco does not recommend this product for 2-tank systems. The next method involves measuring the temperature of the tank walls comparing the vapor gas at the top of the bottle which will be nearly room temperature,...
view full answer... - Using a Vertical 100 Lb. LP Tank On Its SideA tank that is designed to be used in the vertical position should be used in the vertical position. LP tanks are used by drawing of the gas not the liquid. If you change orientation from design of purpose this is being interrupted and possibly introducing an unsafe situation. I strongly recommend against doing this.
