Valve - Avon Redcrest inflatable floor

[Chi34]

Can anyone help identify this valve or suggest an alternative?
It's from 1998. The floor has started to deflate.

I have tried Leafield, who made it, and Ribstore. No good so far.
The floor is quite thin, so most modern valves look too deep.

Although the Redcrest tubes are Hypalon, the floor seems to be PVC.

Finally, there is a 90mm circular patch on the underside, opposite the valve, with a serial stamped on it.
I wonder if this acts as reinforcement or if it covers access to the rear of the valve for a repair?

Anybody been here before?

Have you tried a squirt of washing-up liquid?

That's worth a try. Thanks.

Have you tried a squirt of washing-up liquid?

What do you do just squirt some down the valve neat?

I have a leaking Avon valve I'd love to cure.

Many thanks

Years since I've done it. Certainly worked on the old valves that had the prongs to deflate. I remember a squirt and a couple of bounces with the fork thingy. I think you can unscrew the later ones.

Blimey, that was easy and works a treat.

My valves are the "B7" variety, I just dropped a few drops down the valve and spread it about with a small flat blade screwdriver. Then I pumped it up and its kept its pressure for 24 hours.

Thanks all.
