I would like to make a small gauge block I can attach to the end of my fill hose of my Compressor. I'm thinking a ⅛" NPT "T" type connector that I can attach a Male quick disconnect on one end, a female quick disconnect on the other and a 5000 psi mini gauge in the middle. That should show me the fill pressure right at the fill point so I don't have to keep looking at the gauge on my compressor (which is never right anyway).
Anyone know where I can find a part like that? I would need it to be rated to at least 5000 psi even though it's never see over 3650 psi. I'm thinking something like the block in the picture below. That is an oil pressure feed, so I fear it won't hold up to the HPA pressures we use with air guns. I have all the other parts I need, I just need a high pressure "T" connector. Anyone who can point me to a part that will work, I'd be very appreciative! TIA!

Paul that fitting you have pictured should be able to handle the pressure you are working with as long as it is from a good source . 1/8” NPT is usually rated upwards of 5000 psi in hydraulic applications . If you have a heavy equipment shop near you that’s where I would start looking . Otherwise look online for hydraulic couplers ,I’m sure there are thousands of suppliers out there . Maybe check with JoeB from airtanksforsale.

Thanks Denis! The problem I'm running into is none of these sites list the specs and if they do, they don't include a pressure rating. I have seen some of the brass fitting are only rated to 1000 psi. The one pictured is from AliExpress and I fear it's aluminum. If brass can't handle more than 1000 psi, I would think aluminum would handle even less. I believe I need a fitting that made of stainless steel to get a rating of 5000 psi or more. It sure would be easier if these vendors included more detailed specs! Thanks again...

Here is one, not cheap though.

Ouch! I did find one at Tippman, same specs as that one but $15.00 and $4.95 shipping, so under $20 delivered. I ordered it so hopefully it will work. Thanks.
