MB Sturgis Propane Fittings - 103537-MBS

  • Tees
  • 1/4 Inch - Female QD
  • POL - Male
  • 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. Provides you with a quick-disconnect propane outlet for cooking without disposable cylinders.


Features:

  • T-fitting 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
  • 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
  • 1-Year limited warranty


Note: When using the Sturgi-Stay 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.


Fitting Diagram

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 a quick-disconnect fill hose (sold separately). 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

QDs

The Sturgi-Stay features 2 quick-disconnect ports. The first port connects to the hose from the auxiliary cylinder. The other port provides a connection point for a small, portable appliance or propane tree. 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 hoses without any tools. Simply snap the quick-disconnect hoses (sold separately) 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.

Hey Rick. What kind of accessories are you going to use with the T when you go camping?

by:
A+ As Described!

Great device that allows me to connect an external propane tank to my Motorhome quick and easy. I just take the tank in to refill it.

Seemed like the easiest way to get dual extra output (Buddy heater and grill).

Havent used it. Motorhome sat for the winter because of the Covid.

What I like about this tee compared to other tees on the market is that it has quick disconnects instead of dedicated fittings.
Depending on the hose I use, I can connect one or two external LP tanks - for that extended park, without having to move the coach to get the tank refilled.
Or, I can connect an external appliance, like my portable LP grille, when I'm on a camping trip.
And I don't have to leave the hose attached to the tee where it might accidentally fall down and drag on the ground. When I roll I can just detach the hose and stow it in the basement.
Word to the wise - there's not much room in the LP tank space, SO I recommend getting the hose you want with a 1/4" MPT on the end that you'd want to connect to the tee, plus a Sturgis male quick connect fitting that also has 1/4" MPT. Connect the two together with a regular 1/4" FPT 90 degree elbow. That allows connecting the hose in a tight space.

My RV sits for long periods. This part keeps my LP going by allowing attaching an external portable LP tank. It enabled us to use our RV kitchen while we remodelled our home kitchen.

Have not used this one yet, however, I installed one on my last rig and it worked perfect as it is suppose to. Installation 5 minutes at most, checked no leaks.
by:
Very pleased with the propane hose and fittings I have received from etrailer. The quality of the items seems excellent. The price was very competitive and the items were delivered exactly when they said that they would be. I will be installing these items on my motor home so that I can hook up a B.B.Q. and a campstove.Very happy with the products and service received from etrailer and would feel very confident recommending this site to anyone.

After using for the past year I am still very happy with this product.

This is my second purchase of this product. The valve works as designed and saves a trip to fill the on board propane tank in the Motorhome. It is easy to install. I am planning on using this one with a Webber grill with a built in regulator. Highly recommend if your interested in using portable tanks(easy refill) with a fixed or built in propane tank.

The Sturgi-Stay T fitting is working perfectly. I used the value to add a portable tank during the freezing temps, which saved the fuel in the onboard tank and doesn’t require moving the RV to refill. While camping I connect the grill with the value and there is no need for any additional propane tank. Saves alot of cargo space This is the best option to add to any RV.

by:
Good quality fitting. Would recommend

I ordered this to save money on the 1 lb green tanks. Well it worked great for the first 10 months! It leaks around the on and off valves!! So I removed it before we had a bigger issue as this was connected to my propane tank under my Class A Motorhome.

It is unusual for the fitting to leak however it does have a 1-year warranty. I can send the warranty instructions if you are interested.

2017 Winnebago Forza Motorhome
I used this product to attach a 12' propane hose from the tank on the drivers side of my 2017 Winnebago Forza, underneath to the awning side of the vehicle to power a fire pit. I took The plastic cover off of the tank regulator, unhooked the regulator, and installed this device between the tank and regulator, then re-installed the plastic cover drilling a new hole to install. (The fire pit has it's own regulator). Very easy to do, no pipe dope or teflon tape required. Counting getting under the MH to strap the hose, It probably took about 45 minutes to complete.

I purchased this Sturgis fitting after trying another cheaper brand I found on a major online store. It was a waste of money and leaked from seals and connections from day one. The Sturgis, on the other hand, worked immediately and has been operating flawlessly since day one! Don't spend good money on cheap imitations. Buy good and buy once.

It’s an excellent upgrade

A couple years back, I purchased a different product off the “A” place. It had constant leaks, and the 1/4 inch pol soft nosed connection to the extend a stay tee, was very difficult to seal. Even the cheap, plastic hose broke at the tee end. A lot of propane leaked out over time. Not enough to smell, but soapy water, lots of bubbles. Contacted etrailer, they recommeded this product. First, the tee is made in the USA unlike the cheap Chinese crap I previously purchased off [online store] Second, the connections in this are different, and created a solid seal. NO LEAKS! Third. The two ports are quick connect, saving having to wrench them on and off as I had to on the other model. Fourth, customer service is and always has been first rate at etrailer.

So, overall, etrailer rocks! This is a great product. Saving a couple bucks at the”A” place cost me a lot more than if I just used etrailer in the first place. THANKS GUYS!

Such a brilliant solution for older trailers that don't have a quick connect LP port and allows two accessories like a grill and fire pit at the same time. Worked perfectly on our 1968 Airstream.

Hey Ziyad. With this type of tee, you wouldn't want to use yellow tape. If you had leaking from the get go, it sounds like it would be more of a bad o-ring. I am going to have a replacement sent out to you along with return information so you can get the defective tee back to us.

I've had these on my other RVs. Be careful and check for leaks, usualy around the valve stems. They claim they are rated up to 250psi but the fittings are marked at only 1/2psi. Whats up with that?

So disappointed. Paid extra for Made in the USA and now one of the cut offs is leaking. I contacted CS only to find out that this product has a 90 day warranty. I guess American quality and workmanship isn’t what it used to be.

  • Tee and Hose for Quick-Disconnecting Grill with 1 lb Propane Fitting
    Although it isn't paired together in a kit, you can use the T-Fitting # 103537-MBS with the Quick-Disconnect Propane Hose # 100476-72-MBS for your application. This provides you with the quick-disconnect equivalent of the MB Sturgis Sturgi-Flow T-Fitting w/ Hose for POL Valve # 103608 that you referenced.

    You'll be able to connect your Weber Traveler Grill directly to that quick-disconnect fitting using a hose like the MB Sturgis # 100476-120-MBS as long as your grill doesn't have a regulator. If it does have a regulator then you need a tee fitting like part # 103537-MBS so you can tie into the propane before the regulator. If you were to run your grill through 2 regulators then the pressure would be too low and the grill wouldn't run properly. Attached is a helpful article that goes over...

    Hey Thomas, Since you have a motorhome you should have a large ASME tank. You'll want to go to the connection at the tank and see if you have a tee like the # 103537-MBS. If not you can pick one up and get it installed inline at the tank. Depending on which tee you go with you'll need a hose with a compatible connector for the tee and to the other tank. When your ASME tank runs empty or you just want to conserve it you can shut off its valve, connect the auxiliary tank to the tee, open...

    Hey Mitch! You can’t safely transfer propane from a 20 lb tank into your motorhome tank, those systems aren’t designed for that. What you can do instead is use a tee that lets you run your RV off the 20 lb tank as the supply. The MB Sturgis Sturgi-Stay T-Fitting # 103537-MBS installs between your tank and regulator, and gives you a hookup for a portable tank. This will allow you to switch over to the 20 lb tank so your RV will pull propane from that instead of the onboard tank. What kind...

  • What Parts Do I Need to Run My Propane BBQ off my RV's Propane?
    Hi David, Because both the RV propane and the BBQ grill have a regulator, there isn't a male adapter that goes directly from a male 1-lb bottle thread to an RV quick-connect. Typically, you'd need to find a fitting specific to the grill that you have. Running the propane through two regulators results in really low pressure to the point where you many not be able to light the grill or have a really small flame.
