MB Sturgis Propane Fittings

  • Tees
  • 1 Inch-20 - Male
  • 1/4 Inch - FIF
  • 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 #600 (1"-20) 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
  • 1/4" Female inverted flare inlet lets you hook up a pigtail attached to your auxiliary tank
    • Close the valve on your ASME tank to run appliances with an easily refillable DOT cylinder
    • When valve on your tank is open, can function as an outlet to run an appliance
  • Male #600 (1"-20) port attaches to extension hose to fuel appliances
    • 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
  • 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 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.


The disposable cylinder port on the Sturgi-Stay 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. Simply attach an extension hose (sold separately) to your appliance and then to the disposable cylinder port on the T-fitting.

On our first trip with our CClass we thought we would be in 40 to 65 degree nights… 28 degrees first night with sleet and rain ALL night … had not topped off propane so I was wondering if we will freeze the second night . Heater ran a lot but we made it through … this the Sturge - stay for propane . .. ounce of prevention worth lb of cure. Our camping partners ran out about midnight… I made their coffee that am. Looks like it will extend our stay easily. In my 5th wheel I had installed solar, inverter/charger with no easy way to disconnect the batts . The dc breakers I ordered are working great and I can trip and disconnect solar charging and completely disconnect from system.. What a relief when boondocking !!! No drain at night .. overall I’ve ordered from etrailer for over 20 years , springs , bearings, races, brake assembly’s, etc . Have always been impressed with speed , and product selection!!

All 4 way extened stay valves are the same this is good quality however they are all of a poor desighn. The threaded connection for the stand alone tank should have a shut off valve behind thr threaded connection so you can attatch and unhook the hise without loosing gas. I looked at this then asembled my own T using amazon fittings and a cut off valve. Sturistay is High quality parts just a universal poor set up.This all can be put together with a simple T connected to the regulator then T off to a shut off valve then to the hose connector.

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

by:
A+ As Described!
by:
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.
by:
Seemed like the easiest way to get dual extra output (Buddy heater and grill).
Works fine.

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.

  • Parts Needed to Hook Up to 100 lb Propane Tank on 2019 Grand Design Transcend RV
    From what you described it sounds like you're needing the T-Fitting # 103602-MBS along with the Fill Hose # 100019-144 (for your small tank), the Tank Connector # 204037-MBS, and the 2-Stage Propane Regulator # 108221. Attached is a photo of what this setup looks like and below is a full list of the parts you'll need if all you currently have is the 100 lb tank: T-Fitting - # 103602-MBS Fill Hose - # 100019-144 Adapter Hose - # 100284-144-MBS (for an appliance like the Grill # FR51322) Tank...

  • 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...

    It sounds like you are wanting to use the Camco Big Red Portable Gas Campfire part # CAM58035 with the quick disconnect port on your trailer and if that is the case I do have another option for you but this cannot be done as there is not a low pressure conversion kit that will work with the Camco Big Red Portable Gas Campfire. I confirmed this with my contact at Camco. Instead, you will need to install a t-fitting just before the regulator on your propane tank(s), the MB Sturgis Sturgi-Stay...

  • Pigtail With Excess-Flow Valve For Connecting Auxiliary Cylinder To T-fitting
    I do have an option for you but the JR Products Propane Hose part # 37207-30605 does not have an excess-flow safety device. I recommend to use the MB Sturgis Sturgi-Stay Propane Fill Hose part # 100019-15 instead because it features a ball bearing in the POL fitting that requires a certain amount of pressure to allow gas to flow. If there is not enough pressure for the ball bearing to press down it will not release the propane which means you have a leak somewhere. This pigtail is 15...

  • Direction of Fittings MB Sturgis Sturgi-Stay T-Fitting for POL Valve
    The MB Sturgis Sturgi-Stay T-Fitting for POL Valve # 103602-MBS will work for you even if your connections are on the opposite side; you will only need to flip the valve 180 degrees in order to get your connections on the proper sides.

  • Can Weber Grill Designed for Throwaway Propane Tanks be Supplied by Larger Propane Tank
    Your grill will need regulated propane to function. If you ran high pressure propane it would not function properly and would most likely be dangerous. If you kept the regulator installed on the grill and ran the line to it you should be fine.

  • How To Attach Grill To Quick Connect Port On Side Of RV
    I do have an option for you but most propane grills have built-in regulators and the quick connect port on the side of the trailer is already regulated. Therefore, you'd need to use a tee to splice into the propane supply before the regulator. The MB Sturgis Sturgi-Stay T-Fitting part # 103612-MBS for trailers or part # 103602-MBS for motorhomes along with a hose like the MB Sturgis Propane Adapter Hose part # 100284-144-MBS (confirm grill connection type) will work great.

  • T-Fitting to Hook up Coleman RoadTrip Grill
    There is a solution for you that will allow you to hook up your Coleman RoadTrip and not use 2 regulators on the same line. The MB Sturgis Sturgi-Stay T-Fitting for POL Valve # 103602-MBS will connect to your POL tank while the female POL outlet connects to the regulator on your motorhome and you can hook up your Coleman RoadTrip via the disposable cylinder port. I have added a link to a video review of this product for you to take a look at as well.

  • Propane Tee Length - Most Compacet Tee.
    There's no doubt about it, those propane Tees take up some space and create awkward connections. The MB Sturgis # 103602-MBS would be as good as any of them if those are the connection types you need. Are you adding a Tee for an outdoor grill? Do you need gas that comes after the pressure regulator? Maybe a better idea is to follow your gas line after the regulator. Most likely there is a hose after the regulator that runs to 1/2" iron NPT pipe that then runs under the coach and goes...

  • Solution for Supplying RV Propane Tank to Grille with Regulator Built In
    The issue would be that you have two regulators feeding the grill. What you'd need is a tee installed between the RV regulator and the tank so that you can feed the grill unregulated propane. To do that you'd want the part # 103602-MBS for if you have a POL valve on your tank or part # 103612-MBS if you have a Type 1 valve.

  • Can You Install a Rubber Hose Between the Tank and MB Sturgis Sturgi-Stay T-Fitting
    The MB Sturgis Sturgi-Stay T-Fitting part # 103602-MBS should be threaded directly into the tank. If you don't have clearance for this on your setup you may need to purchase some adapter fittings or alter your existing setup. That said, there isn't any sort of rubber hole that would connect the tank to the tee. If you have hard lines, you can use them with this tee so long as the fittings are correct. I can't comment on which exact adapter you need for your setup but you can take a look...
