RE: Shower hose fittings problem

I've been doing most of my own house plumbing for 30+ years, including a couple fixer-uppers. I spent part of my career as a chemical engineer, which is basically just an overpaid plumber. :) I actually understand plumbing pretty well. I am not crossthreading here.

RE: Shower hose fittings problem

No, I'm putting the long, tapered connector on the head, and the short nut on the diverter. Swapping the hose end-for-end doesn't help. Both ends of the hose have female NPT, which I can confirm because they easily thread onto another NPT fitting that I have. So the diverter is the odd thread. The more I look into this, the more I'm thinking that the diverter is actually a "G" thread, aka BSPP (British Standard Pipe, Parallel). The fitting doesn't seem to taper, which could be why the hose won't thread onto it. Apparently BSPP is what is used in much of the rest of the world? Not sure why it would show up on my Jayco, though. I'm going to order an adapter from Amazon and try it. One other thought - this connector was made to seal with a washer, not with thread tape. BSPP is designed to seal with a washer, but NPT is designed to seal along the threads, not with a washer. So now I'm wondering if we all have BSPP on our diverter, and for some reason I got a bad hose which has NPT instead of BSPP?

RE: Shower hose fittings problem

The diverter is original, and I'm sure it's not metric - it's 1/2-14. I don't have the old hose anymore. I can try stacking washers, but it's going to take 3/8 or 1/2 inch of them.

RE: Shower hose fittings problem

if I grab a 1/2 NPT male, I can screw it into either end of the hose. However on the end that goes into the diverter, I can only get it a few turns before it starts to tighten. The threads are definitely 1/2"-14, but maybe the taper is off? I can actually get it more than 1/2 turn onto the diverter - that was a mistake - but I can't get it tight enough to mate the washers. The thread get tight before the washers mate.

Shower hose fittings problem

I have a Jayco travel trailer. I needed to replace the shower hose, so I bought one off of Amazon. I can screw the 'head' end of the hose onto the head, no problem. However when I go to screw the other end onto the faucet diverter, it goes on maybe a half turn and sticks. At this point the internal mating surfaces are not pressed together - the hose rattles loosely in the nut - so it is not a watertight seal. I've played with this for hours, although the fittings look the same, and the thread pitch is the same, the fittings won't go together. Has anyone had this issue before? Is there some adapter I need? I thought these things were all 'universal'. BTW, this is the hose I bought. Cheap enough to just get a different one, but I don't know if that will help. Blissland Shower Hose
