What thread for a 23000 psi pressure gauge?
What thread for a 23000 psi pressure gauge?
(OP)
Gents
I am about to order a new pressure gauge for our hydrailc bolt stretching tool.
The thread is 14 TPI
OD 0.82" (20.9mm)
but at the end there is a smaller cylindrical bit with an o-ring around it measuring:
OD 0.23" (6.0mm)
Length 0.19" (4.8 mm)
This to me is an G 1/2" or 1/2" BSPP, but how do I specify it to get the cylindrical part with the O-ring at the bottom. (see file attached)
This is very high pressure and I don't want to get it wrong.
Regards,
Rigpig

Newport scientific took over for Aminco who I believe made the original cone and thread style fittings.
There are other manufacturers that I've not used so I can't vouch for them.

It is not a quick connection. I see that the photo I uploaded is not so good, but it is threaded 14 TPI with a boss with an O-ring at the end.
I have seen this on pressure gauges before, but do not know what it is called.

Checkout these gauges the connection is listed as G-1/2". CEJN might be one avenue to approach your problem.

Here are two types of O-ring seals for hydraulic fittings you might want to check out.

Just an observation:
We have 8 different tensioning devices as well a number of heavy hydraulic jacks and none have an operating hydraulic pressure of greater than 10.000 psig.
Just a question :
Does your gage indicate system pressure or tension on the fastener?

'½" BSPP Gauge Connection, Bottom Entry (all BSPP gauge connections come with the spigot)'
Was it really that easy?

Glad you resolved your issue. All you have to do now is get a new gauge.
