This check valve is inexpensive and provides cheap insurance for your regulator. Very quality product and easy to install. Recommended for any regulator without a check valve built in.
I added this with a wye splitter to a dual pressure regulator to split a gas line. The regulator already came with a ball check valve so this had to be added to the splitter._x000D__x000D_I ear clamped the air line straight to the end of this and it appears to be sealed well.
