Parker FB6TEU4-HBLK Push-to-connect Plug 3/8 Od Kynar

Product Description

The PARKER FB6TEU4-HBLK is a push-to-connect plug fitting designed to terminate or cap off tubing runs without tools. It accepts 3/8 inch OD tubing with a 1/4 inch ID and locks in place through the push-to-connect mechanism. Constructed from Kynar (PVDF) with an FKM o-ring, this fitting is rated to 250 psi and handles a vacuum rating of 28 in-Hg. The black color coding helps differentiate it on multi-line installations. It is suited for plumbing, HVAC, and industrial fluid-handling applications where a clean, secure tube termination is required without threaded fittings or solvent welding.

This fitting is used to plug or dead-end 3/8 inch OD tubing in residential and light commercial fluid systems. Typical applications include chemical fluid lines, water treatment systems, pneumatic circuits, and instrumentation tubing where a positive seal against backflow or contamination is needed. The Kynar body resists a wide range of aggressive chemicals, making it a common choice in corrosive-fluid environments. Installation requires no special tools beyond ensuring the tubing end is cut cleanly and squarely before insertion.

Key Features

• Push-to-connect design allows tool-free installation and quick tube termination
• Kynar (PVDF) body provides excellent chemical resistance for aggressive fluid service
• FKM o-ring sealing element compatible with a broad range of fluids and temperatures
• Rated to 250 psi with a vacuum rating of 28 in-Hg
• Black color coding supports easy line identification on multi-circuit installations
• Compact form factor fits in tight plumbing or instrumentation panel layouts

Compatibility

Designed as a push-to-connect plug for 3/8 inch OD tubing with a 1/4 inch ID. Suitable for use in systems where Kynar fittings and FKM seals are specified for chemical compatibility.

Installation Notes

This fitting is installed by licensed plumbers, HVAC technicians, or instrumentation technicians depending on the application. Before installation, depressurize and isolate the tubing circuit completely. Ensure the tubing end is cleanly cut and free of burrs or deformation before inserting into the push-to-connect collet for a leak-free seal. Verify that the system fluid and operating pressure are compatible with Kynar and FKM materials before placing the fitting in service.
