Parker 32PTC-6 Push-to-connect Union Fitting 3/8 in

Product Description

The PARKER 32PTC-6 is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid transfer systems. It accepts 3/8 inch OD tubing on both ends and creates a secure, tool-free connection rated to 250 psi. The composite body construction keeps weight low at 0.03 pounds while offering solid resistance to common system fluids. A nitrile O-ring provides the primary seal. This fitting is installed by plumbers, pipefitters, and HVAC technicians in applications where quick, reliable tube connections are required without threaded fittings or compression tools.

The 32PTC-6 is suited for residential and light commercial systems where 3/8 inch OD tubing is routed through pneumatic controls, fluid lines, or low-pressure distribution manifolds. Its push-to-connect design allows rapid assembly and disassembly, making it well suited for service work where tubing must be disconnected and reconnected during maintenance or system modifications. The composite body is appropriate for clean or mildly corrosive service environments.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians. Before servicing any line, depressurize the system fully and verify pressure has reached zero before disconnecting tubing. Ensure tubing ends are cut square and deburred before insertion to maintain a proper O-ring seal. Verify the tubing OD matches the fitting rating before installation.
