So refreshing to do business with a company ( that is knowledgeable about their products and how they are used. They were so helpful in working with me to select the right products for my project. After receiving delivery I had a few questions about how to make the connections. I made a call to and again received excellent help. Vert satisfied with their service


I took a chance on ordering this propane connector not certain if it would fit the Enerco two stage automatic change over regulator for my generator but it fitted like a glove,I was all set to look around for adaptors and was very glad that I didn't have to if you send me a phone number I can send you pictures of what I've been working on and your products help me to achieve that thanks don't know how to send photos from my tablet I've been setting up a whole house generator hook up for a year and a half my hook up is complete


Excellent assistance when I call , product came in a few days, works great. Left it overnight in 15 degree temperatures worked great the next morning.


This propane hose is exactly what I was looking for and couldn't find in local stores.

  • Recommended Temporary Propane Hose From Tank to House
    In order to choose the correct propane hose you will need to know what size fittings you have on either end of the accessories that the line will be hooked up to. If you are referring to a dual stage propane regulator such as the MB Sturgis Horizontal 2-Stage Propane Regulator part # 108221 then these usually have a 3/8" NPT outlet. If that is the case then the MB Sturgis High Pressure Propane Hose part # 100040-144-MBS is the longest we have at 12' but you could certainly combine multiple...

  • Propane Hose for Cummins Onan RV Generator
    Thank you so much for the info and the pictures! According to my research it looks like your Cummins Onan RV Generator uses a 3/8" NPT Female fitting so you'll need a hose like part # 100040-144-MBS. I have attached a link to all of our hose selections that have the 3/8" male and female ends that you can filter through. I'm not quite sure what end you'll need to connect this to a regulator/propane tank as it looks like the male end goes into your generator when it is normally supposed...

  • Solution for Needing 50 Foot 3/8 inch Fitting Propane Hose Rated for 350 psi
    The closest thing we offer is the # 100040-144-MBS which is rated for 350 psi and has 3/8 inch NPT and 3/8 female flare fittings but is only 12 feet long. You'd need 5 of these to total 50 feet.

  • Hose Kit to Go From RV Propane Tank to Propane Regulator

  • Can MB Sturgis High Pressure Propane Hose be Used on Trailer
    The location of where you installed the MB Sturgis High Pressure Propane Hose # 100040-144-MBS would dictate how well it would perform under a trailer. If you had it directly behind a wheel and exposed you'd be asking for a problem. If you installed away from a wheel and not exposed you'd be fine in that regard. Now there are several laws and regulations on how propane lines should be ran that you'd need to check out as you have to consider how things will behave in an accident.

  • Are Fittings on MB Sturgis High Pressure Propane Hose a Left Hand Thread

  • What are the Correct Hoses for the MB Sturgis High Capacity Auto Changeover Regulator 108260
    There are three ports on the MB Sturgis High Capacity Auto Changeover Regulator 108260. The two 1/4" female inverted flare inlets will attach to the propane tanks with a hose like the MB Sturgis Propane Pigtail part # 100575-12-MBS and the single 3/8" FNPT outlet will attach to the propane manifold on the trailer with a hose like the MB Sturgis High Pressure Propane Hose part # 100040-144-MBS. I have attached a review video of both propane hoses for you. I was not able to reference the...

  • Recommended Propane Regulator and 8 to 10 Foot Hose to Supply a Food Trailer
    To supply your food trailer from your 100 pound tank you're going to need a pigtail, like part # 100473-20-MBS, that goes from the tank to a regulator. The regulator needs to be a 2-stage regulator like part # 108220. Then from the regulator use part # 100040-144-MBS. It's 12 feet long so more than what you need but we don't have an 8 to 10 foot hose that has a 3/8 male to connect to a regulator with a 3/8 female flare on the other end. The next shortest option we carry is 6 feet long,...

  • How to Hook a Converted Propane Clothes Dryer Up To a 100 Lb Propane Tank
    The MB Sturgis Vertical 2-Stage Propane Regulator part # 108220 will work with your 100 lb propane tank if mounted straight up and down so that the vent is facing the ground (see photo). In order to attach this regulator to the tank you will need to use the MB Sturgis Hose Assembly part # 100202. In order to recommend the correct fittings and hose to attach the outlet of the regulator to your clothes dryer I would need to know what fitting you have on your clothes dryer. If you do not...

  • Recommendations For Van Build Propane System
    You're going to need a regulator if you don't have one hooked up already so I would run a line from your tank to a regulator like Item # CAM59323 and then you can run a line like Item # 100040-144-MBS up into your van and up to the appliances. Depending on the type of connection you have up inside the van for the appliances you could choose a different hose to match that connection. You could definitely bend some conduit and run the hose through it and bracket it onto the underside of the...

  • How To Hook Up Generator to 100 Lb Propane Tank
    The propane regulator requirements will be specific to the generator, usually in the form of a BTU rating so you'll have to reach out to the manufacturer of your generator to see what they recommend. The Excess Flow 2-Stage POL RV LP Gas Regulator part # 37207-30375 will attach directly to a 100 lb propane tank and can flow up to 225,000 Btu's per hour. You could then use the MB Sturgis High Pressure Propane Hose part # 100040-144-MBS to direct the supply to the generator but you may also...

  • Parts Needed For Connecting Two 100LB Propane Tanks To a Furnace
    You will most likely need the MB Sturgis High Capacity Two-Stage Auto Changeover Regulator # 888001-MBS for going to your furnace. Be sure to verify with the furnace manufacturer that a 11" WC regulator that delivers 450,000 Btu P/HR is compatible with that furnace. With this auto changeover regulator it will draw propane from one tank until empty and then switch over to the 2nd tank automatically so you won't have to change anything to the 2nd tank.

  • Do I Need a Separate Low Pressure Regulator for a Camco Olympian Wave Heater
    Yes, you will need to use a low pressure regulator with the Camco Olympian Wave 8 part # CAM57351 but that is what the Camco Horizontal 2-Stage Propane Regulator part # CAM59323 is. Therefore, if you have the heater tied in after the above regulator then you won't have any issues. In order to attach the Camco Olympian Wave 8 to the manifold on your trailer you are most likely going to need the MB Sturgis High Pressure Propane Hose part # 100383-36-MBS for 3' long, part # 100040-72-MBS...

  • Replacement Propane Trunk Hose from Regulator to Trailer
    It's hard to tell from the pictures what size fittings are being used but what you need is a trunk hose from your regulator to the trailer. Once you know the size of each fitting it shouldn't be difficult to find a hose. It looks to me likes it's probably a 3/8 inch for both of them which means you can use part # 100040-48-MBS for a 4 foot, part # 100040-72-MBS for a 6 foot, or part # 100040-144-MBS for a 12 foot.

  • Longer than 12 Foot Long Feed Hose for Camco Olympian Wave 8 Catalytic Safety Heater
    12 feet is the longest hose we have with a regulator on it like the part # CAM57721 that you mentioned but you could use a second hose with this to get a longer overall hose. For example you could connect the # 100040-144-MBS to the # CAM57721 and you'd have a 24 foot long setup.

  • Size of Propane Hose to Go From Tank to Regulator on RV
    Most regulators like the part # CAM59005 have an inlet of 1/4 inch SAE and an outlet of 3/8 NPT. It would be out of the ordinary if your tank to regulator wasn't 1/4 inch SAE inverted flare. Part # CAM59053 has this style of fittings on both sides. Part # 100040-144-MBS has 3/8 inch on the other hand. Heres how you tell difference between 3/8 NPT and 1/4 NPT. The difference is the outside diameter. 1/4 inch is .540 outside diameter on the threads and 3/8 inch is .675 inch.

  • Parts Needed to Connect DOT Propane Tank to RV
    You will need a regulator to supply your RV with propane as all RV propane accessories are designed for low pressure propane. The first thing you'll need is a pigtail to plug into the DOT cylinder you want to use. For that you'd want the part # 100473-12. Next you'd want a regulator like part # 108220 and then a hose to connect to your trailer.

    The 21" Stainless Steel Furrion 2-in-1 Range Oven # FSRE21SABL has a 3/8” Male Flare fitting. If you are wanting to use a 20 or 30 lb propane tank with this oven then I recommend using the 4' # 100040-48-MBS, 6' # 100040-72-MBS, or 12' # 100040-144-MBS hose along with a dual stage regulator, part # 108220 with the fitting # 204120-MBS for a single tank or part # CAM59005 for dual tanks.

  • Regulator and Hoses Required for a Dyna-Glo 20000 BTU Wall Heater
    According to the user manual for Dyna-Glo wall heaters, they require a propane gas line pressure of 11in WC (water column). You will need a 2-stage regulator to reach this pressure level like part # 37207-30375. This regulator comes with the POL fitting that will thread directly into the valve on your tank and you will just need a supply hose to go from the regulator to the heater.
