Parker FB4TMC2 Tube Stem Adapter 1/4 in Od Kynar 250 Psi

Product Description

The PARKER FB4TMC2 is a push-to-connect tube stem adapter designed for use in fluid and pneumatic systems where a quick, reliable tube-to-thread connection is required. Constructed from Kynar (PVDF), this fitting handles pressures up to 250 psi and carries a vacuum rating of 28 inches Hg, making it suitable for both pressure and vacuum applications. It accepts 1/4 inch OD tubing and threads into a 1/8 inch NPTF port. The FKM O-ring provides a positive seal against a wide range of fluids and chemicals. Plumbers, HVAC technicians, and industrial maintenance professionals install this fitting where corrosion resistance and secure push-to-connect engagement are priorities.

This adapter is used in residential and light commercial fluid handling, pneumatic control lines, chemical transfer systems, and instrumentation tubing runs. It is well suited for applications where Kynar chemical resistance is specified, such as systems handling aggressive fluids or operating in corrosive environments. The black color and compact form factor allow installation in tight panel or manifold locations. The NPTF thread type provides a dry-seal connection without requiring additional thread sealant in many installations, depending on media and system requirements.

Compatibility

Designed as an OEM-style push-to-connect tube fitting for systems using 1/4 inch OD tubing and 1/8 inch NPTF ported components in pneumatic, fluid handling, or instrumentation applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or instrumentation technicians. Depressurize and isolate the system fully before removing any existing fittings or inserting tubing. Confirm tubing OD is true 1/4 inch and that the tube end is cut cleanly and squarely before inserting into the push-to-connect collet. Verify thread compatibility and apply appropriate thread sealant per system requirements and applicable codes such as IPC or IFGC where applicable.
