Parker 8 Rbu-s Bite-type Male Run Tee 1/2 in Od 3/8 Nptf

Product Description

The PARKER 8 RBU-S is a flareless bite-type tube male run tee designed for use in fluid power and instrumentation tubing systems. This fitting accepts 1/2 inch tube OD and threads into a 3/8 inch NPTF port, creating a secure, leak-resistant branch connection without the need for flaring. The bite-type design uses a ferrule that deforms onto the tube wall during assembly, forming a mechanical grip and seal in a single operation. Licensed plumbers, pipefitters, and fluid power technicians install this fitting in hydraulic, pneumatic, and industrial fluid lines where a run-tee configuration is required.

This male run tee is suited for inline branch connections in industrial machinery, fluid distribution manifolds, and process piping where 1/2 inch OD tubing terminates into or passes through a 3/8 inch NPTF threaded port. The flareless bite-type design is common in applications where field flaring is impractical or where a compact, vibration-resistant connection is preferred. It is sold individually and ships in a package quantity of one.

Key Features

• Flareless bite-type design eliminates the need for tube flaring during installation
• Male run tee configuration allows an inline branch connection at a single fitting
• 3/8 inch NPTF male thread provides a dry-seal, pressure-tight threaded connection
• Accepts 1/2 inch OD tubing for compatibility with common instrument and fluid power lines
• Compact form factor suits tight-space installations in machinery and panel assemblies

Compatibility

Designed as an OEM-style replacement or new-install flareless tube fitting for fluid power and instrumentation systems using 1/2 inch OD tubing and 3/8 inch NPTF ported components.

Installation Notes

Installation should be performed by a qualified pipefitter or fluid power technician familiar with flareless bite-type fitting procedures. De-energize and depressurize the system completely before disassembly or fitting installation. Follow the fitting manufacturer's nut-turn method for initial assembly to ensure proper ferrule bite without over-compression. Verify thread sealant compatibility with system fluid before applying any thread compound to NPTF connections.
