Parker PP6BU6 Bulkhead Union Fitting 3/8 in Od

Product Description

The PARKER PP6BU6 is a push-to-connect bulkhead union tube fitting designed for tube-to-tube connections through a panel or wall. Constructed from polypropylene with a tan color finish, this fitting accepts 3/8 inch OD tubing on both sides and is rated to 150 psi. Installation requires no tools for the tube connection itself — tubing inserts directly into the fitting body and locks in place. Plumbers, HVAC technicians, and industrial service pros use this type of fitting where a line must pass cleanly through a bulkhead surface without threaded fittings or additional hardware.

This fitting is suited for residential and light commercial applications involving pneumatic tubing, water lines, or fluid transfer systems where a panel pass-through is required. Polypropylene construction offers resistance to a range of chemicals and moisture, making it a practical choice in both indoor mechanical and utility environments. The push-to-connect design allows for fast field assembly and straightforward tube removal when needed.

Installation Notes

This fitting is typically installed by plumbers, HVAC technicians, or industrial mechanics. Ensure the tubing end is cut cleanly and squarely before insertion to achieve a proper seal. Shut off and depressurize the line before installing or removing the fitting. Follow all applicable local plumbing and mechanical codes when integrating into pressurized systems.
