Parker 8-8-8 Rbu-s Flareless Bite-type Male Run Tee 1/2 in

Product Description

The PARKER 8-8-8 RBU-S is a flareless bite-type tube male run tee designed for use in hydraulic and instrumentation tubing systems. This fitting accepts a 1/2-inch tube OD and connects to a 1/2-inch NPTF male thread, creating an in-line branch connection without the need for flared tube ends. The bite-type design uses a ferrule to grip and seal the tube mechanically, eliminating the preparation steps required for flare fittings. It is sized and configured for use by plumbers, pipefitters, and hydraulic system technicians working on fluid-transfer or pneumatic line installations.

This fitting is suited for applications in hydraulic systems, pneumatic plumbing, and industrial fluid-transfer lines where a tee connection is needed at a threaded port. The male run configuration allows the fitting to thread directly into a female NPTF port while continuing the tube run through both ends of the tee. NPTF threading provides a dry-seal connection that does not rely solely on thread sealant. It is appropriate for both light industrial and commercial system builds requiring secure, leak-resistant tube junctions.

Key Features

• Flareless bite-type design eliminates tube flaring during installation
• 1/2-inch NPTF male thread provides dry-seal port connection
• 1/2-inch tube OD sizing for standard hydraulic and pneumatic tubing
• Male run tee configuration allows in-line branching at a threaded port
• Compact single-piece fitting suitable for tight plumbing layouts

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic, pneumatic, and fluid-transfer systems using 1/2-inch OD tubing with 1/2-inch NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. Depressurize and isolate the system completely before removing or installing any tube fittings. Ensure tube ends are cut square and deburred before inserting into the bite-type ferrule seat. NPTF threads are designed for dry-seal engagement, but thread sealant may be applied per system requirements and applicable plumbing codes.
