The built-in check valve provides direct contact with the fluid, when TCSS Series Hydraulic Stainless Steel Test Couplings are connected. The screw-in design allows test couplings to be connected even when the system is in operation and under high pressure. Internal threaded metal dust cap protects the Test Coupling from contamination and damage. TCSS Series Hydraulic Stainless Steel Test Couplings have an excellent resistance to corrosion with AISI-316 L Stainless Steel body.
