Hydraulic Products, Press-Check / 359 - Screw to Connect Pressure Testing (ISO 15171-2)

Gauge connections

There are three designs for pressure gauge connections within the Press-Check range: bulkhead pressure gauge connection (fig.1), pressure gauge coupling (fig.2) and 90° pressure gauge swivel connection (fig.3). The pressure gauge coupling is available in two versions, one free flow and one with pressure damper.

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.
