Parker FB8WY8-HBLK Push-to-connect Union 1/2 Inch Od

Product Description

The PARKER FB8WY8-HBLK is a push-to-connect union tube fitting designed for tube-to-tube connections in fluid and pneumatic systems. It accepts 1/2 inch OD tubing on both ends and uses a tool-free push-in connection mechanism, making it a practical choice for inline unions where quick assembly or field replacement is required. The body is constructed from Kynar (PVDF), a chemically resistant fluoropolymer suited for aggressive media applications. The black color finish and FKM o-ring material round out the key material specs. Rated to 250 psi and carrying a 28 in-Hg vacuum rating, this fitting handles both pressure and vacuum service. Licensed plumbers, industrial pipefitters, and chemical system technicians are the typical installers.

This fitting is well suited for residential and light commercial fluid handling systems where chemical compatibility and reliable push-to-connect simplicity are priorities. Kynar construction makes it appropriate for use with corrosive or high-purity fluids, including certain chemical feed lines, water treatment systems, and laboratory or industrial plumbing. It works as an inline union to join two runs of 1/2 inch OD tubing without threading or soldering. Applications span HVAC chemical treatment loops, pool and spa chemical dosing systems, and general industrial plumbing where PVDF material compatibility is required.

Key Features

• Push-to-connect design allows tool-free tube insertion for fast field assembly
• Kynar (PVDF) body construction provides strong chemical resistance for aggressive media service
• FKM o-ring material compatible with a broad range of chemicals and solvents
• Rated to 250 psi working pressure
• 28 in-Hg vacuum rating supports both pressure and vacuum system use
• Black color body for easy visual identification in multi-line installations

Compatibility

Designed for use with 1/2 inch OD tubing in push-to-connect tube-to-tube union configurations. Suitable for systems requiring PVDF material compatibility and FKM o-ring sealing.

Installation Notes

Installation is typically performed by licensed plumbers or qualified industrial pipefitters. Before servicing any pressurized line, depressurize and drain the system completely. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect fitting body to achieve a proper seal. Verify that the tubing OD and material are compatible with the fitting and the media being conveyed before placing the system into service.
