Hi everyone,

I got hold of an old Nu-air compressor with a busted pressure relief valve which I'm replacing, the previous owner just had a bit of wood holding the pin in... The thread is 1/2 inch but i read on here it is called a 3/4 inch relief valve, is that right? It's also got a leaky pressure regulator which I don't know if thats much of a problem

this is the first compressor I've ever had so I know very little, whatever I can learn from here would be really appreciated.

I've attached some photos of the key components to help.

Many thanks in advance.
