What is the voltage rating of M20*1.5?
Thread Content
I have chosen an on-site pressure gauge with a connection specification of M20*1.5. What is the pressure rating of this connection specification?
I think it’s fine to use this connection specification for various ranges, such as 0~1MPa and 0~4MPa, right?

Our company specializes in pressure instruments up to 100 MPa. We have conducted pressure tests on threaded connections, and there were no issues; for higher pressures, we need to consult relevant documentation
I’ve never used one at 100 MPa; just hearing about it is terrifying.
Our unit’s hydraulic system operates at 60 MPa, and using M20*1.5 connectors works fine
Generally, regular pressure gauges are fine, but it’s hard to say anything about those from unreputable brands that use inferior materials
