If Quicksilver sibs uses Halkey Roberts air valves doesn't matter if being a twisting nozzle or plain ones as the ones posted, as long there's a central pin in middle nozzle to push valve pin slightly for gauge to read properly. Properly it's not same as accurately. Accurately is another storry.

Happy Boating

Pressure guages

Hi all
My first try at replying to a posting so sorry if it all goes wrong.

I thought I could add my solution.
My Honwave has Halkey Roberts valves and have made up a gauge to test pressures, I have 2 similar gauges so check them against each other every now and then.
I use these fittings and bought the grey one on ebay, it has a small screw inside that you adjust to lift the valve off its seat,(I think it came from Force4).
The second black one came with the boat and has a small moulding inside that also lifts the valve but is not adjustable.
I also have a grey one fitted to my pump so it is not pumping against the valve spring.
I hope the photos are clear enough to see details

My boat has the H-R valves (new, short.)

I use a standard adaptor that's been cross drilled, and inserted a short piece of SS wire (about .060") to push on the center plunger in the valve. I'd have to look, but as I recall, the drilling is about 1/4" above the bayonet tang. I'll see if I can get a pic this weekend. This was for use with a Bravo electric pump though (which needs the valve opened); not for a gauge, though it would work there too.

A big thank you to Max.Got one of these pressure guages and cobbled it together using Max's idea and anything readily to hand. If it helps anyone I assembled like this:- ptfe tape around the brass thread and slip a lenght of garden hose over, mine is the braided type about 9inches long. Secure with a hose clip. Into the other end of the pipe slide in a piece of 15mm copper pipe, insert an inch or so and leave half an inch protruding. Get a nozzle from a painters caulk tube (similar to a silicone tube nozzle but bigger) and cut off the threaded section. Slide the cut end up over the end of the protruding copper tube and secure where the plastic nozzle meets the hosepipe with another hose clamp. This will give you a long rigid tapering tube to trim wit a craft knife into the shape of long fingernail to insert into the Zodiac type valve. That's it, am amazed just how much under pressure I was running at.
