Parker PP4FC2 Push-to-connect Connector 1/4in Od 1/8in Nptf

Product Description

The PARKER PP4FC2 is a push-to-connect tube-to-pipe connector fitting designed for quick, tool-free tubing connections in fluid and pneumatic systems. Constructed from polypropylene with a tan color finish, this connector accepts 1/4 inch OD tubing and threads into a 1/8 inch NPTF female port. Rated to 150 psi, it is suited for low-pressure liquid and air lines where corrosion resistance and lightweight construction matter. Plumbers, HVAC technicians, and industrial maintenance professionals use this fitting to simplify tube routing without soldering, compression tools, or flare equipment.

This fitting is typically used in residential and light commercial applications including water treatment systems, pneumatic control lines, ice maker supply lines, RO filtration assemblies, and HVAC condensate or sensing tube connections. Its push-to-connect design allows tubing to be inserted and locked in seconds, making it a practical choice for tight spaces and high-volume installations where speed and reliability are both priorities.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure locking
• Polypropylene construction provides corrosion resistance for water and mild fluid service
• Rated to 150 psi for low-to-medium pressure pneumatic and liquid applications
• 1/8 inch NPTF thread ensures a pressure-tight seal with tapered pipe threads
• Compact, lightweight form factor suitable for confined installation spaces

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 1/4 inch OD tubing and 1/8 inch NPTF threaded ports in plumbing, pneumatic, and fluid handling applications.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified maintenance personnel. Shut off the fluid or air supply and depressurize the line before servicing any fitting. Ensure tubing is cut square and deburred before inserting into the push-to-connect collar to achieve a proper seal. Verify NPTF thread engagement is sufficient and inspect for leaks before returning the system to service.
