Pipe dope is like cement. Pressure relief fittings too small
Like this but the pre applied teflon pipe dope is like cement. I got 1 thread of engagement before I didn't feel comfortable applying more torque. Soaked dope in acetone for an hour which loosened it up. Hit it with a small flat blade screwdriver to take off the first layer and soaked for another hour. Rest came off with a brass brush. Applied normal teflon tape and got regular thread engagement. Pressure relief fittings have a lot of restriction for the size of the pipe fittings. I can see these working on 1/4 NPT where they aren't relieving high volumes of pressure but using these on a 100mm x 150mm pneumatic cylinder I feel like these slow the speed of the piston significantly and also make a lot of noise (would probably happen regardless). I opted to run plastic lines instead to reduce the pressure drop and route them to minimize noise.

Great valve my my project.
Installed them on Vacuum system on my truck and they work great. Only bad review is saw was that the knob is too loose and falls off. I added a little loc-tite to the knob. That seams to have solved the issue.

worked perfectly for my can crusher
I used this to control an air ram for a can crusher that I made. Nice smooth operation and no leaks. I took off the plate opposite from the button and found it is already bored for a spring. I was able to just drop in a spring so that it works as a momentary switch now. Now I don't need to pull the switch back out to get it to retract the ram.
