VEP Series Flat Face Couplers

Stucchi VEP Series flat-faced couplers are a popular solution for hydraulic circuit applications subject to high-pressure impulses and circuits which experience high residual or trapped pressure in a line.

The thread-to-connect design eliminates premature wear or brinelling, a patented internal valve allows connection/disconnection with high residual pressures, and the flat face design avoids loss of hydraulic fluid and contamination into the circuit. A yellow o-ring indicator makes the VEP series even easier to work with.
