Parker FB6TMC6 Tube Stem Adapter 3/8 Inch Od Nptf

Product Description

The PARKER FB6TMC6 is a push-to-connect tube stem adapter designed for use in fluid and pneumatic plumbing systems where a secure, tool-free tube connection to a threaded port is required. Built from Kynar (PVDF) with an FKM o-ring, this fitting handles working pressures up to 250 psi and vacuum service up to 28 in-Hg. The black Kynar construction offers strong chemical resistance, making it suitable for aggressive fluid environments. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in process piping, instrumentation lines, and fluid transfer assemblies where a quick, reliable push-in connection is needed.

This adapter is suited for light industrial, commercial, and process applications where tubing with a 3/8 inch outside diameter must connect to a 3/8 inch NPTF threaded port. It is appropriate for systems handling compatible fluids and gases within the rated pressure and vacuum range. The push-to-connect design allows fast installation and removal without additional compression hardware. Applications include instrumentation tubing runs, chemical dosing lines, and fluid handling systems where Kynar-grade chemical resistance is a specification requirement.

Key Features

• Kynar (PVDF) body provides excellent chemical and UV resistance
• FKM o-ring seat compatible with a wide range of aggressive media
• Rated to 250 psi working pressure
• Vacuum rating of 28 in-Hg supports suction-side applications
• 3/8 inch NPTF thread provides a pressure-tight tapered pipe thread connection
• Push-to-connect design allows tool-free tube insertion and release

Compatibility

Designed as an OEM-style push-to-connect fitting for 3/8 inch OD tubing systems with 3/8 inch NPTF threaded ports. Verify thread type and tubing outside diameter before installation.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters familiar with push-to-connect fittings and tapered pipe thread connections. De-pressurize and drain the system completely before removing or installing any fitting. NPTF threads are self-sealing by design, but confirm thread engagement and system pressure rating before returning the line to service. Follow applicable plumbing and process piping codes for the jurisdiction and application type.
