It's not my pressure relief valves

But I'm got some air leaking around the flange. Is it easy to unscrew them without losing the backing plate? I heard lube them up with silicone?

I've never looked for whole setup. My tubes came with 4 chambers capped and 3 with relief valves. I found the 4 needed on ebay for $12/ea (I should have bought more as Wing charges $30/ea).

I've seen how the whole thing goes together. The large ring of plastic has a male and female piece and they just screw together to to sandwich the fabric (this is where you hope you can get them tight enough, I don't think that there's any adhesive or sealant). The PRV then screws into the center.

I tried tightening the male/female connections a while back but was marring the plastic trying to get a grip so I figured there had to be a secret way. I talked to "I love ribs" yesterday and he said just to crank them down and not worry about marking up the plastic with your pliers.

I'd love to open the male/female up and make sure that it's clean and maybe put some silicone to try to create a better seal but I'm worried about loosing the backing into the tube chamber.

jky, thanks. The PRV's themselves are fine; it's just that air is leaking around them. The ones we have are made by SEI. I would think installing new ones like you showed on that link would involve cutting the tube?

don't know how yours are fixed to the tube, but I have taken my valves and pressure relief valves off to clean and lube them, no issues with losing the fixing as they were glued in. Just try one and see what happens

Anytime. The reply was actually for JohnDoe's benefit though.

Hope you get things working.

As an aside, are your OPV's installed on a donut, or simply a hole cut in the fabric? My inflatable repair guy (not that I've ever used him) says that ideally, they should be installed on inside and outside doubler patches.

valves

If you know who made them I would get the correct tool to tighten and loosen them with. try taking them apart and tightening them properly. Once you get them loosened a bit deflate the tube and grab the back side of the valve through the fabric. Finish disassembling and put a line through the valve hole and tie the inside base with the line so you don't lose it. I'd clean it up and put it back together, but NEVER use silicone. Any type of grease or lube is just going to attract grit to the valve and make a bigger mess in the long run.

Best of luck !
