Parker PP8TMC6 Push-to-connect Tube Stem Adapter

Product Description

The PARKER PP8TMC6 is a push-to-connect tube stem adapter designed to transition between a push-to-connect tube connection and a threaded pipe fitting. Constructed from white polypropylene with an EPDM o-ring, this adapter handles pressures up to 150 psi and suits fluid-handling applications where chemical resistance and lightweight construction matter. The 1/2 inch OD tube side accepts standard push-to-connect tubing, while the 3/8 inch NPTF threaded end provides a secure, drip-tight connection to compatible ported equipment or manifolds. Plumbers, HVAC technicians, and fluid-system installers use this fitting in low-pressure water and chemical distribution lines.

This adapter is suited for residential and light commercial plumbing, HVAC condensate systems, water treatment equipment, and similar low-pressure fluid-handling installations where polypropylene construction provides adequate chemical and corrosion resistance. The push-to-connect design allows fast, tool-free tube insertion, making it practical for tight spaces or high-volume assembly work. The NPTF thread form provides a pressure-tight mechanical seal without relying solely on thread sealant.

Key Features

• Push-to-connect 1/2 inch OD tube end for fast, tool-free tube insertion
• 3/8 inch NPTF threaded end for a drip-tight connection to ported components
• Polypropylene body offers corrosion resistance and chemical compatibility
• EPDM o-ring provides reliable sealing across a range of fluid types
• Rated to 150 psi for low-pressure fluid-handling applications
• White color aids visual identification in multi-line installations

Compatibility

Designed as an OEM-style push-to-connect tube stem adapter compatible with 1/2 inch OD tubing and 3/8 inch NPTF threaded ports in low-pressure fluid-handling systems.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Shut off the water or fluid supply and relieve system pressure completely before installing or removing any fitting. Inspect the tubing end for squareness and burrs before insertion into the push-to-connect end, as irregular cuts can compromise the o-ring seal. Apply NPTF-compatible thread sealant or PTFE tape to the threaded end as required by local plumbing code.
