Common questions
Will this fit an older Parker hand valve?
Parker notes that the current hand shut-off valve plugs and bonnet assemblies will not retrofit to prior design hand shut-off valve bodies or prior design stop valves. Match the valve size, connection type and body style to the 80-01 L parts tables before ordering.
Specifications are based on Parker Refrigerating Specialties Bulletin 80-01 L (Hand Shut-Off Valves) and the Parker R/S Parts Kits list PK-16. Confirm fit, ratings and application requirements before ordering.
