I went through 7 of these pigtails including the two that came with the trailer before having a local industrial hose and fitting supplier make 2 new hoses for me.
I had a continual problem with leakage between the hose and the hose barb on the crimped end fittings. During winter camping I only had 2 of the original 30 lb propane cylinders that came with the trailer. My alternate cylinders were 20 lb. Part of the problem was with cold-weather camping the hoses were extremely stiff. When switching to a different size cylinder the hose had a tendency to turn slightly on the barb since it was too stiff to flex enough without turning. Eventually they would leak.
As a permanent fix I purchased 2 green Acme nut x male pipe thread fittings from a propane supplier. I then had an industrial hose supplier manufacturer 2 hose assemblies for me consisting of a heavier hose that was 1/4 ID rated for propane use and able to withstand over 350 pounds of pressure. I had them install a female pipe thread connection on one end and a 45 degree flared female swivel nut fitting on the other end. Instead of crimp fittings on the hoses I wanted to use fittings that had threaded collars to secure the hoses but they were going to cost about $80 each. They guaranteed that their crimped fittings wouldn't leak. They've helped me with a special hose assembly for a truck I used to own and I've been dealing with them for years and trust them so I went with the crimped fittings they recommended. I also purchased 2 straight male pipe thread by male 45° flared fittings and two 45 degree male by female pipe thread elbows from them I needed to complete the connections.
I removed the male pipe thread by reverse flare fittings that were screwed into the regulator connections for the hoses and replaced them with the 45 degree elbows to get the correct angle needed for the new shorter hoses. I added the two straight male pipe thread by male 45 degree flared fittings to each of the elbows. I then added the Acme nuts to the two hoses then connected the two hoses to the 45 degree flared fittings. No more leaks.
The new hoses are heavier and shorter than the originals with a larger outer diameter. The cut length of the new hose before assembly was about 7 to 8 inches. When using the shorter 20lb cylinder I can loosen the 45 degree flare nut to let the hose rotate as needed to connect to the shorter tank and then retighten the nut.
Wow, thanks for sharing your fix with us. I definitely will talk to our local bulk propane operations. --- But my point is since this is the first time in 9 rigs and 45 years of rving that this has happened to me, there must be over the counter brands put together better than others.
