Product Made In Japan
Manufacturer: IHARA SCIENCE CORPORATION
Model: FF Quick Joints

Features

Ihara Science FF Quick Joints have been developed as an alternative to the conventional quick joint.
Keeping the “Easy Desorption” of the quick joint, maximizes flow path area (full flow) reduces pressure loss and saves energy.
Equipped with fail-safe mechanism (cannot be detached when [Open], does not [Open]when detached).
Accidental operation prevention has been implemented.
