Hydraulic Quick Couplings
General Purpose
SM Series double shut-off couplings are versatile for use
across a spectrum of hydraulic applications where fluid lines
require connection and disconnection. Couplers and nipples
are steel with nitrile seals and are available in 1/4 through 3/4
inch sizes.
Features:
•
Rated pressures up to 6000 psi
•
Poppet valves have captive seals to minimize seal washout
•
Steel material with standard nitrile seals
•
Standard end configurations include female pipe, straight
thread ORB, and British pipe
•
Alternative seal materials available
Applications:
•
Industrial hydraulic lines
•
Mobile equipment
