Parker PP6MC6 Push-to-connect Connector 3/8 in Od Nptf

Product Description

The PARKER PP6MC6 is a push-to-connect tube-to-pipe connector fitting designed for fast, tool-free tube connections in fluid handling systems. It accepts 3/8 inch OD tubing and connects to a 3/8 inch NPTF threaded port. The body is molded from polypropylene, giving it solid resistance to moisture and many common chemicals encountered in plumbing, HVAC, and light industrial applications. Rated at 150 psi, it handles typical low-to-moderate pressure service without additional sealants on the compression side. Licensed plumbers, HVAC technicians, and maintenance mechanics install this type of fitting where quick-connect tube terminations are preferred over compression or flare ends.

This fitting suits residential and light commercial installations where polypropylene tube or compatible tubing runs to a threaded pipe port. Common applications include water supply lines, condensate drain routing, pneumatic controls, and instrumentation tubing. The NPTF thread form provides a pressure-tight mechanical seal on the pipe side. The tan polypropylene construction is standard for push-to-connect fittings used in non-potable water and process fluid circuits, though compatibility with specific fluids should be verified against Parker published chemical resistance data before installation.

Key Features

• 3/8 inch OD tube connection with 3/8 inch NPTF male pipe thread
• Polypropylene body offers chemical and moisture resistance
• 150 psi pressure rating suitable for low-to-moderate pressure service
• Tan color coding aids quick identification on mixed-fitting installations
• Compact connector profile fits tight spaces in panel or equipment enclosures

Compatibility

Designed as an OEM-style push-to-connect connector for systems using 3/8 inch OD tubing terminated to a 3/8 inch NPTF threaded port in plumbing, HVAC, or light industrial fluid handling applications.

Installation Notes

Shut off the fluid supply and relieve system pressure before installing or removing this fitting. Ensure the tube end is cut square, deburred, and clean before insertion to achieve a proper internal seal. Apply thread sealant tape or compound to the NPTF pipe thread per local plumbing code requirements. To release the tube, depress the collet ring evenly while pulling the tube straight out — do not twist or force the tube at an angle.
