Parker 67PLP-4M-8M Reducer Straight Tube Fitting 300 Psi

Product Description

The PARKER 67PLP-4M-8M is a push-to-connect tube-to-stem reducer fitting in a straight configuration, designed for use in pneumatic and fluid line assemblies. Constructed from nickel-plated brass with a silicone-free grease, this fitting connects a 4 mm outside diameter tube to a stem-style port. It holds a maximum working pressure of 300 psi and operates across a temperature range of 0 degrees F to 200 degrees F. The yellow release button allows quick disconnection without special tools. At 0.03 pounds and 1.58 inches in overall length, it is a compact, reliable fitting suited for tight installation spaces. HVAC technicians, pneumatic system builders, and plumbing contractors are the primary installers.

This fitting is used in residential and light commercial applications where push-to-connect convenience is required at a reducer junction between mismatched tube and stem sizes. It is well-suited for pneumatic control lines, refrigeration accessory circuits, and fluid handling assemblies where a fast, tool-free connection is needed. The nickel-plated brass construction provides corrosion resistance in moderate-humidity environments. The UL94 V-0 flame resistance rating makes it appropriate for installations with fire-rated assembly requirements.

Compatibility

Designed as an OEM-style push-to-connect reducer fitting for pneumatic and fluid line assemblies requiring a tube-to-stem connection with a 4 mm outside diameter tube.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pneumatic system technicians. Before servicing any line, depressurize the system fully and verify pressure is at zero before disconnecting or installing fittings. Insert tubing straight into the fitting until it seats fully to ensure a secure, leak-free connection. Inspect the tube end for burrs or damage before insertion, as surface defects can compromise the seal.
