Parker FB6EU6-HBLK Push-to-connect Union 3/8 in Od

Product Description

The PARKER FB6EU6-HBLK is a push-to-connect union tube fitting designed for quick, tool-free connections in fluid and pneumatic systems. Built from Kynar (PVDF), this fitting handles up to 250 psi and is rated for a vacuum of 28 inches Hg, making it suitable for both pressure and vacuum service. The black color and FKM o-ring construction indicate compatibility with a range of chemicals and fuels. Licensed plumbers, pipefitters, and industrial maintenance techs install this style of fitting where fast, reliable tube unions are required without threading or soldering.

This fitting is suited for residential and light commercial plumbing, chemical fluid handling, pneumatic control lines, and laboratory or process piping where Kynar's chemical resistance is required. The 3/8 inch OD push-to-connect design accepts standard 3/8 inch OD tubing on both ends, allowing an inline union connection with minimal assembly time. Typical applications include chemical dosing lines, water treatment systems, and compressed air or vacuum circuits where a leak-free, reusable union is needed.

Compatibility

Designed as an OEM-style push-to-connect union for standard 3/8 inch OD tubing in pneumatic, fluid, and chemical handling systems.

Installation Notes

Depressurize and isolate the line before disconnecting or installing any push-to-connect fitting. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. This fitting is typically installed by licensed plumbers, pipefitters, or industrial maintenance personnel. Verify that system pressure and fluid compatibility are within the rated limits of Kynar and FKM before placing the fitting in service.
