What kind of temps and pressures can this sight plug actually handle out in the field?

Question by: Frank P on Dec 26, 2025, 8:31 AM

Rated up to 500 degrees Fahrenheit and 1500 psi working pressure, so it holds up well in pretty demanding industrial setups. The electroless nickel plated steel body helps it resist corrosion on top of that, which matters a lot when you're running hot fluids through tight equipment day after day.

got a tank port that’s 3/4 NPT. is this the right thread for that, or am i gonna be fighting it?

Question by: Rex F on Aug 11, 2025, 4:14 PM

Thread fit comes down to the connection type, and this plug is made with a 3/4 NPT thread, so it matches standard 3/4 NPT ports.
