Parker FB5FC4-HBLK Push-to-connect Fitting 5/16x1/4 in

Product Description

The PARKER FB5FC4-HBLK is a push-to-connect tube fitting connector designed for quick, tool-free tube connections in fluid handling and pneumatic systems. Built from Kynar (PVDF) for chemical resistance and durability, this fitting accepts tube outside diameters of 5/16 inch and 1/4 inch and is rated to 230 psi. The push-to-connect design allows the tube to seat with a single insertion, holding firmly under pressure without additional fittings or sealants. Licensed plumbers, pipefitters, and HVAC technicians working with chemical-resistant tubing lines will find this connector a direct, efficient solution for inline tube joining.

This fitting is suited for residential and light commercial applications where chemical-resistant, push-connect fittings are required. Common install scenarios include water treatment lines, chemical feed systems, HVAC condensate and fluid lines, and laboratory plumbing where Kynar construction provides resistance to aggressive media. The connector format makes it appropriate for straight inline tube runs where a secure, leak-free joint is needed without threading or compression tools.

Key Features

Compatibility

Designed as an OEM-style replacement or inline connector for systems using push-to-connect fittings with 5/16 inch and 1/4 inch OD tubing in Kynar-compatible fluid handling or pneumatic plumbing installations.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified technician. Before servicing any fluid line, depressurize the system fully and isolate the supply. Ensure tube ends are cut square and deburred before insertion to achieve a proper seal. Verify that tubing material is compatible with Kynar fittings and rated for the system pressure prior to installation.
