How to Order Information
Available with Sleeve-Lok (See Coupler Options Section).
To order, add the suffix “-SL” to part number, Example: B33-SL.
Brass valves are available for extra corrosion resistance. To
specify a brass valve, add the suffix “N” to the regular part
number. Example: B33N. A brass valve should be used for
corrosive applications where steel parts are not suitable.
Consult the factory for specific recommendations.
Features
• Parker 30 Series couplers are designed for rigid mounting
that allows a simple push-to-connect operation.
• Constructed of a solid brass body and a steel valve, 30
Series couplers are noted for their high flow capability,
reliability and rugged design.
• Parker 30 Series couplers accept industrial interchange
nipples manufactured by Parker and other manufacturers.
• Standard seal material is Nitrile. See Ordering Information
at the beginning of Section A and the Fluid Compatibility
Chart at the end of this catalog for optional materials.
Operation
Push type couplings feature one handed “automatic”
connection by pushing the nipple into the coupler–provided
the coupler half is firmly mounted.
The locking mechanism of Parker 30 Series couplers consists
of pawls (or pins) which act directly on the sleeve, thereby
causing the sleeve to automatically retract when the mating
nipple is inserted.
Sleeve must be manually retracted to remove the nipple.
30 Series couplings are push type Single Shut-Off couplings.
