Parker’s Snap-tite 71 Series couplings are designed for
working pressures up to 10,000 psi. Available in a variety of
materials and with a wide range of body sizes. Air inclusion and
fluid loss are minimal with the flush face valves. Large flow
chambers in the body and an exclusive valve design premit
superior flow while maintaining low pressure drop.
Features:
•
Flush face/Non-spill
•
Push-to-connect
•
Heavy duty construction
•
Designed for up to 10,000 psi (690 bar) working pressures
•
Variety of materials
•
Wide range of sizes
•
Superior flow and low pressure drop
•
Sleeve lock option to protect against accidental
disconnection.
Applications include:
•
Industrial hydraulic lines
•
Off-shore drilling
