Parker W68PLP-3-2 Push-to-connect Male Connector 3/16 in

Product Description

The PARKER W68PLP-3-2 is a push-to-connect male connector fitting designed for tube-to-male NPT pneumatic and fluid line connections. Constructed from nickel-plated brass, it accepts 3/16-inch outside diameter tubing on each tube port and threads into a 1/8-inch NPTF male port. The fitting is rated to 300 psi maximum working pressure and handles temperatures from 0 degrees F to 200 degrees F. The nitrile O-ring provides reliable sealing across a wide range of media, and the push-to-connect button is black flame-resistant material certified to UL94 V-0. Ideal for control line work where fast, tool-free tube connections are required.

This fitting is used in pneumatic control systems, HVAC equipment, refrigeration controls, and light industrial fluid lines where a compact inline connection between small-diameter tubing and a male NPT port is needed. The push-to-connect design allows a technician to insert tubing without ferrules, compression nuts, or additional tooling. The NPTF thread form creates a pressure-tight mechanical seal without requiring additional sealant on correctly machined ports, though sealant is commonly applied per shop practice. Overall installed length is 0.85 inches, making it well suited for tight panel or manifold installations.

Key Features

• Push-to-connect tube ports accept 3/16-inch OD tubing — no ferrules or compression hardware required
• 1/8-inch NPTF male thread for pressure-tight tapered thread connections
• Nickel-plated brass body for corrosion resistance in moderate-duty environments
• Rated to 300 psi maximum working pressure
• Operating range of 0 degrees F to 200 degrees F
• Nitrile O-ring sealing; UL94 V-0 flame-resistant release button
• Compact 0.85-inch overall length for space-constrained installations

Compatibility

Designed as a standard push-to-connect male connector for pneumatic and fluid control systems using 3/16-inch OD tubing and 1/8-inch NPTF male ports. Suitable for use with compatible tubing materials and media that are consistent with nitrile O-ring and nickel-plated brass construction.

Installation Notes

Installation is performed by licensed HVAC technicians, refrigeration mechanics, or industrial maintenance technicians. Depressurize and isolate the line completely before disconnecting or installing any fitting. To connect, insert clean, square-cut tubing firmly into the push-to-connect port until it seats; to release, press the collar and withdraw the tube. Inspect tubing for burrs or ovality before insertion, as irregular tube ends are the most common cause of push-to-connect leaks.
