Parker FB4MRS4-HBLK Male Swivel Run Tee 1/4 in Od Kynar

Product Description

The PARKER FB4MRS4-HBLK is a push-to-connect male swivel run tee tube fitting designed for use in pneumatic and fluid-handling systems where fast, tool-free tube connections are required. Built from Kynar (PVDF) with an FKM o-ring seal, this fitting handles up to 250 psi and carries a vacuum rating of 28 in-Hg, making it suitable for both pressure and vacuum applications. The black color coding aids in quick system identification. It accepts 1/4 inch OD tubing and connects to a 1/4 inch NPTF male thread port. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is used in residential and commercial fluid distribution, pneumatic control lines, chemical handling systems, and instrumentation plumbing where Kynar construction provides resistance to aggressive media. The push-to-connect design allows fast field assembly without ferrules, compression sleeves, or special tooling. The swivel run tee configuration permits inline branching while allowing the male thread end to rotate for easy port alignment during installation. It is sold individually with a minimum order quantity of one.

Key Features

• Kynar (PVDF) body construction for chemical resistance in demanding fluid and pneumatic service
• FKM o-ring seal compatible with a broad range of media including hydrocarbons and many acids
• 250 psi rated pressure with 28 in-Hg vacuum capability
• Push-to-connect design allows tool-free tube insertion and positive retention
• Swivel male thread end simplifies port alignment without stressing the tube connection
• Black color for visual system identification and circuit differentiation

Compatibility

Designed for use with 1/4 inch OD tubing and 1/4 inch NPTF male thread ports in push-to-connect pneumatic and fluid-handling systems.

Installation Notes

Installation is typically performed by licensed pipefitters, instrumentation technicians, or plumbers following applicable IPC and system-specific pressure codes. Depressurize and isolate the line before removing or installing any fitting. Ensure the receiving port threads are clean and free of damage before threading the swivel end; apply appropriate thread sealant compatible with Kynar and the system media. Insert tubing fully into the push-to-connect collet until it seats, then tug lightly to confirm retention before returning the line to service.
