Parker 67PLP-4M-10M Reducer Straight Tube Fitting 300 Psi

Product Description

The PARKER 67PLP-4M-10M is a push-to-connect tube-to-stem reducer straight fitting designed for use in pneumatic and fluid distribution systems. Constructed from nickel-plated brass, this fitting connects a 4 mm outside-diameter tube to a stem-type port in a straight, in-line configuration. It handles maximum working pressures up to 300 psi and operates across a temperature range of 0 degrees F to 200 degrees F. The silver body and yellow release button allow quick identification and tool-free tube insertion and removal. Installation and service are handled by licensed HVAC technicians, plumbers, and industrial mechanics working on compressed air, control line, and fluid-conveyance systems.

This fitting is suited for residential and light commercial applications where space-efficient, reliable push-to-connect joints are required. Typical scenarios include pneumatic control lines, HVAC equipment tubing runs, and other low-to-medium-pressure fluid systems that call for a reducer configuration — stepping down from one tube size to a smaller stem connection. The silicone-free grease specification makes it appropriate for environments where silicone contamination is a concern, such as paint booth air lines and certain sensor-feed circuits.

Key Features

• Push-to-connect design allows tool-free tube insertion and release via yellow button
• Nickel-plated brass construction resists corrosion in wet and humid service environments
• 300 psi maximum working pressure for low-to-medium-pressure pneumatic and fluid lines
• Rated from 0 degrees F to 200 degrees F for broad temperature compatibility
• UL94 V-0 flame resistance standard compliance
• Silicone-free grease — safe for silicone-sensitive applications

Compatibility

Designed as an OEM-style push-to-connect reducer fitting for pneumatic and fluid tubing systems requiring a 4 mm outside-diameter tube connection to a stem-type port.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Before servicing any fitting, shut off and bleed down the pressure source to zero psi. Ensure tube ends are cut square and deburred before insertion to achieve a proper seal. Follow all applicable mechanical and plumbing codes for the jurisdiction and system type.
