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 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 fill 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 a quick-disconnect hose into the port and it will stay locked in until you release it. To remove the hose, just pull back on the collar of the port. 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.

I saw this on a neighbors rv and looking it up I found it on your site. I wanted It because we stay in RV parks and this makes It easy to attach my 20lb.propane bottle. It was easy to order and fast service. I liked the tracker that I could follow the delivery. I also appreciate the follow up email. Thank you

Best thing Ive bought. It works great. I also bought a gauge to let me know when the tank is low so I can switch it easily.

Excellent product! Wanted a single port quick connect but found this. I'm glad I did and the price was very good as compared to others I found. This allows me to stay longer and use two external tanks while saving my on board propane in the motorhome. I can leave one connected and go fill the other.

- 103538-MBS

Very nice tee with protectors. Quick connects are tight and I love the safety locks. Shipped quick and was well worth the price.

- 103538-MBS

Product was received on time. A better design than others like it. It was easy to install on my Georgie Boy. Don't buy the cheap ones on other sites, some of them have male fittings for the hose which break off.

- 103538-MBS

Awesome. Very easy install. Works exactly for my needs.

- 103538-MBS

This is a great product, at a good price, from a superior store. Installation was quick and easy. (took longer to leak-check everything, than to install) Now I don't have to worry about propane delivery at some of our extended stay destinations. The fittings, connections, and hoses are all first class. Thanks ETRAILER, for having great videos, pictures, and descriptions on everything!!

Went together without any problems. Prompt shipping and quality fittings.

Had to return item and reorder (my fault picked the wrong part). The friendly staff processed my request, went smooth with an easy exchange. Installation went smooth. Really solved the inconvenience of taking the RV out on an empty LP tank. Thanks etrailer.com

  • Parts Needed to Connect Portable Propane Tank to Motorhome for Auxiliary Source
    You need to Tee into your propane line before the regulator, like you mentioned and connect a portable DOT tank in there. Part # 103538-MBS is a tee that fits between your built in ASME tank and your current regulator and it has 2 quick disconnect fittings on it. The included hose connects a DOT tank to one of those quick disconnect fittings so you can run off that tank instead of your built in tank. This keeps you from needing to pack up your motorhome and go somewhere just to fill...

  • Recommended Regulator and Hose for Grill Connection to Motorhome Tank with POL Fitting
    For the MB Sturgis Sturgi-Stay T-Fitting w/ Hose for POL Valve - 2 Model 250 Quick Disconnect Ports # 103538-MBS you will put this between the tank and the motorhome's in line regulator. Then you will need a single stage regulator like # CAM59013 which will thread onto the 3/8 inch male pipe of your grill and then you will need an adapter like # 204129-MBS to thread into the inlet of the regulator and provide you a female fitting for the male POL that is integrated on the T-fitting.

  • Tee for Adding 100 lb Propane Tank to Dual Tank Set Up
    You are on the money because you will in fact be able to use the MB Sturgis Sturgi-Stay T-Fitting w/ Hose for POL Valve - 2 Model 250 Quick Disconnect Ports # 103538-MBS. This will be all you need, though one of the ports is for adding a small appliance like a grill, so you would not be able to hook up a fourth tank. I have added a link to a video review of this product for you to check out as well.

  • Will MB Sturgis Sturgi-Stay T-Fitting # 103538-MBS Fit a 524AS Horizontal Regulator
    It looks like there is 3/8" NPT fitting attached to the regulator on your propane tank like hose # 100040-48-MBS which has a 3/8" female flare fitting on the other end. Based on that MB Sturgis Sturgi-Stay T-Fitting # 103538-MBS would not work. I checked the regulator model and it is indeed a 3/8". It also has a 1/4" port on it so MB Sturgis Sturgi-Stay T-Fitting # 103610 is a possibility. The fill hose has a 1/4" male inverted flare and a POL connection on the other side to connect...

  • How To Switch Propane Supply on 1981 Tioga RV to 20 Pound Propane Cylinder
    The only ways to transfer more propane to your onboard tank is to take your RV to a refill station or have a propane truck come to your location to fill it. Chances are that a truck will not come to you for such a small purchase. Another alternative is to use an outdoor 20 pound propane tank. You will need the MB Sturgis # 103538-MBS extended stay T-fitting. Where your gas line from the RV connects to the tank you can install this T-fitting. The included hose will run from your T-fitting...

  • Tee Fitting Needed to Connect Auxiliary 20 lb Tank to Propane System
    What you need is a T-Fitting and auxiliary hose like what comes in the Kit # 103538-MBS, but your propane setup is a bit different than a normal RV so you'll need to get creative in how you're able to connect the T-Fitting. One end is a male POL connection, which will connect to your valve, while the other end has a female POL fitting. Then you have the 2 quick-disconnects and a hose that allows you to connect your 20 lb auxiliary tank. You can definitely use the T-Fitting # 103602-MBS...
