I need a pressure gauge

[VanillaIceCream]

Hi, I'm new to this forum and just purchased my 3rd inflatable, a 1998 Zodiac YL 420 DL series 2828 with an Johnson 50 hp. I'll post more of it on the introductory page, but I don't even have any pictures of it yet.

I'm looking for a pressure gauge but haven't had any luck finding the correct one that will give a reading, I believe due to the diaphragm doing its job and keeping the air in.

I've tried the local rafting company that sells NRS, but none work.

I've email two inflatable boat stores in the USA a week ago, but no response.

I would prefer to buy the correct gauge, but if I have to I could make an adapter that pushes the diaphragm aside to let air flow and get a pressure reading with another gauge.

1. Are these the Delrin valves on this model of Zodiac? I have a exploded parts list for the boat but that diagram doesn't say what type of valve, just pictures and p/n's.

2. What pressure gauge to use with or without an adapter?

98 Zodiac likely uses some form of Halkey Roberts valve ( I think.)

Check out NRSWeb.com; they've got most things inflatable. If you can't find what you need on the site, e-mail or call them.

I will call them, but the rafting store here in Colorado has all those gauges and adapters in stock, none of which worked. The rafting store was of great help, but.... the owner since 1988 didn't recognize the Zodiac valves.

(Not a lot of RIB's here in Colorado, but lots of white water rafts).

If you're 'handy', make one for a few $'s:

If you have an adapter that fits the valve (and allows you to inflate the tube), you can cross-drill said adapter and insert a piece of solid wire at the height you need to depress the plunger.

I had to do this to my HR adapter to get a pump to work, as the low pressure high volume stage wouldn't pump against the diaphragm. As I recall, I measured from the rim of the valve (where the adapter seals) to the height of the plunger, then added a quarter inch or so. Just make sure you drill small enough that the wire is held captive in the adapter (not that it would go anywhere, but you'll probably find it missing at exactly the wrong time.)

Yes I thought of this, but I thought Zodiac would sell a pressure gauge without having to do this. I'm concerned that any adapter I make will someday drop the some a part into the tube.

(If I cannot find a proper pressure gauge, I'll probably just make an adapter, but I prefer to use stock parts for this.)

Ok, I think this gauge will work (it says it will) and it comes with a bunch of adapters.



Scoprega SP 125 Manometer Pressure Gauge


Anyone use this one? Junk or good? I'll wait a week to order after input from you all.
