The test point nipples for the Press-Check system are available with plastic or metal dust caps and comes in four different sealing types; metal to metal seal, sealing by fitted ring, sealing by thread and sealing by O-ring.

Press-Check Monitoring System for hydraulics consists of a wide range of test points, minihose and couplings for monitoring and testing of circuits in mobile and hydraulic equipment. It can be installed at any point of the hydraulic system were pressures needs to be monitored. The system is designed and manufactures according to ISO 15171-2 and is fully interchangeable with several other brands.
