That is how blowers die. The check valve is the cheap part that stands between the water and the expensive one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow it is built\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe seal is drip proof, which keeps air from leaking out of the line, and the spring is a 1\/4 lb. dome shape chosen to give balanced, even airflow rather than a hard snap. That spring is Underwriters Recognized stainless steel, so it holds up in the warm, wet air a blower line carries.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir Supply lists the valve for 1 1\/2 inch IPS and 2 inch O.D. spigot, and the union connection means it can be taken off for service without cutting into the pipe.
