KQH10-03S Applications
The KQH10-03S connects a ø10 mm tube to an R3/8 threaded port and includes factory-applied thread sealant for an immediate leak-tight seal. Its rugged metal (brass) one-touch body handles vibration and harsh conditions better than resin, making it well suited to feeding compressed air into cylinders, valves and manifold ports in machine tools, automation cells and general pneumatic circuits. Rated from vacuum to 1.0 MPa.
