Parker FB4TPL Push-to-connect Tube Plug 1/4 Inch Od

Product Description

The PARKER FB4TPL is a push-to-connect tube plug fitting designed to seal off 1/4-inch OD tubing lines in fluid and pneumatic systems. Constructed from Kynar (PVDF), this plug resists aggressive chemicals, UV exposure, and elevated temperatures — making it a reliable choice for plumbing, chemical handling, and industrial fluid-control applications. The FKM o-ring provides a secure, leak-resistant seal at the tube interface. Rated to 250 psi and a vacuum rating of 28 in-Hg, this fitting handles both pressure and vacuum service. The push-to-connect design allows fast, tool-free termination of tubing runs without threading or soldering.

This plug fitting is suited for residential and commercial applications where an open tubing port needs to be capped or a line needs to be temporarily or permanently terminated. Typical install scenarios include capping unused ports on manifolds, isolating sections of tubing during service, or blanking off supply lines in chemical dosing and water treatment systems. It is compatible with 1/4-inch OD tubing and is sold individually.

Installation Notes

Installation of this fitting is performed by plumbers, HVAC technicians, or industrial fluid-system technicians. Before installing or removing the plug, depressurize and isolate the tubing line completely. Insert tubing or cap the port by pressing the fitting firmly until it seats — no tools are required for connection. Verify the line remains depressurized before disconnecting by pressing the release collar before pulling the tubing free.
