Parker FB8BU8-HBLK Bulkhead Union Fitting 1/2 Inch Od

Product Description

The PARKER FB8BU8-HBLK is a push-to-connect bulkhead union tube fitting designed for tube-to-tube connections through a panel or wall. Constructed from Kynar (PVDF) with a black finish, this fitting accepts 1/2 inch OD tubing on both sides and allows technicians to make or break a connection without tools. The FKM o-ring provides reliable sealing compatibility with a broad range of fluids and gases. Rated to 250 psi and with a vacuum rating of 28 in-Hg, it is suited for both pressure and vacuum service in demanding plumbing and fluid-handling applications. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

This bulkhead union is intended for use in systems requiring a tube pass-through at a panel, bulkhead, or enclosure wall. The Kynar body makes it appropriate for chemical-resistant installations, including water treatment, chemical processing, and specialty HVAC or pool-chemical feed systems where corrosive or aggressive media are present. Both connection ports accept 1/2 inch OD tubing, making it a straightforward inline bulkhead solution for panel-mount plumbing runs.

Key Features

• Push-to-connect design allows tool-free tube insertion and release on both ports
• Kynar (PVDF) body offers strong chemical and UV resistance
• FKM o-ring sealing for compatibility with a wide range of fluids and chemicals
• Rated to 250 psi working pressure

Compatibility

Designed as an OEM-style push-to-connect bulkhead union for systems using 1/2 inch OD tubing, compatible with standard push-to-connect plumbing and fluid-handling installations where a Kynar fitting body is specified.

Installation Notes

Installation should be performed by a qualified plumber or pipefitter in accordance with applicable local plumbing codes. Before installing or removing the fitting, depressurize and drain the system completely. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. Do not exceed the rated working pressure of 250 psi or the vacuum rating of 28 in-Hg in service.
