Hydraulic Products, Snap-Check / 358 - Quick Connect Pressure Testing

Couplings and Nipples

  • Connect under pressure up to 30 MPa
  • Compact design
  • High working pressure
  • One-hand operated
  • Dust caps included as standard


The couplings and nipples of the Snap-Check system have a maximum working pressure of 60 MPa. This ensures extra long, leak-free service and unsurpassed reliability. The system can also be connected under pressure up to 30 MPa on the nipple side and is available with G, R, NPT, UNF and metric threads. Couplings and nipples come with standard red dust caps to keep them clean and prevent dirt from entering the system.


CEJN's Snap-Check pressure testing system, monitors and diagnoses fluid systems in a snap. This monitoring system identifies operating pressure surges without the need for a permanently installed gauge. Applications include mobile equipment, injection molding machines, oil and gas equipment, marine vessels, and production machinery. For specific requirements, customized systems are available that include a wide range of gauges.
