TwistMate's unique "twist to connect" and pressure assisted grip and seal is simple to use.  Turn finger-tight onto thread until face seal contacts test piece. TwistMate will automatically seal when the system is pressurized with air, gas or hydraulic pressure that presses the main seal against the test piece.  The internal piston action maintains the seal with minimum pressure.

  • Leak testing - water dunk, pressure decay, helium mass spectrometer
  • Calibration, filling, pressure and proof testing
  • Ideal for piping, cooling, heating, fluid, hydraulic, pneumatic, refrigerant and fittings
  • Eliminates tape, sealants, wrenches and damage to threaded parts
  • Durable, easy to replace main seal

TwistMate connectors are not designed for or intended as permanent connections.  Such use may result in inadvertent loosening and media loss.
