WHY WE NEED IT: When your air compressor pressurizes the surrounding air, the water vapor or humidity can be condensed as water. This water then sits in the bottom of your tank. The main issue with having water in your air compressor’s tank is that it can cause the tank to rust from the inside out, weakening the walls. A drain valve performs the critical function of allowing excess water vapor to escape into the atmosphere.

EXTEND TANK DRAIN ASSEMBLY: Includes a 1/4” elbow with pre-applied thread sealant, 10 inch flexible braided steel hose and 1/4” quarter turn drain valve. Max working pressure: 175 PSI. Blasting Pressure: 475 PSI. Max Temperature: 200 degrees F.

DURABLE&FLEXIBLE: Flexible braided steel hose covers and protects silicone drain hose. Ensuring quality and durability, rust-proof, burst-proof and anti-corrosion, protecting inner tube and preventing leakage.
