Fitting Challange!

Hi,

Can anyone help recommend a fitting for me? Its for an RV shower/sprayer.

I need it to pass through and clamp securely to a 1/2 inch thick plywood wall. On the inside of the wall it needs to connect to 3/8 id flex hose that runs to a pump, on the outside it needs to connect to a sink sprayer.

Any fittings or combinations you can recommend?

Thanks!

hope this gives the idea...

maybe something like this. you can solder in an adapter to convert end to a threaded fitting to attach 3/8 tube. then screw in an adapter to attacjh your hose. Big box stores have a lot of fittings to choose from

just a basic hose clamp sounds like it might work.

Thanks for your replies so far.

Here's what I came up with. You might be wondering why I'm asking for help if I already have a solution. This has worked well for me, but I'm trying to put together kits for a few friends with the same camper van and there are some problems...

this is elbow fitting I used:

Problem 1: It works well, but its too expensive!

It looks like this (since its on the outside aesthetics matter):



and on the inside:


Like I said, it works okay but problem 2: It's a shower/bidet sprayer, probably PVC and probably not food safe (the sprayer is used to fill drinking water bottles and cooking pots all the time). I found a picture on-line of what pruports to be a kitchen sink sprayer with the right straight threaded end fitting for my elbow, but I have no idea where to buy it (the web-page I took the pic from doesn't sell it and was no help):


So if anyone can offer advice on how to get a food safe hose with the right fitting attachment, and/or cheaper elbow, that would be much much appreciated!

Thanks!

ps, sorry for spelling challenge wrong
