Parker 8-4 Cbz-b Brass Compression Male Elbow 1/4 in Mnpt

Product Description

The PARKER 8-4 CBZ-B is a brass compression tube male elbow fitting designed to connect tubing to male NPT threaded ports at a 90-degree angle. It uses a compression-style end on one side and a male pipe thread (MNPT) on the other, making it a standard choice for routing tubing changes of direction in pressurized fluid and gas systems. Rated to 2200 psi maximum working pressure, this fitting is built for demanding applications where a reliable, leak-tight connection is required. Brass construction provides corrosion resistance and compatibility with a wide range of media. The 1/4 inch thread size suits common instrumentation and control line work. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the typical installers.

This fitting is suited for use in refrigeration, pneumatic, hydraulic, and general-purpose fluid systems where a compression tube must terminate or transition into a male NPT threaded port. The 1/4 inch MNPT thread size is common in control line, instrument tubing, and process connection work found in both light commercial and industrial settings. Its compact elbow geometry helps navigate tight equipment cabinets and panel enclosures where straight fittings cannot be routed cleanly.

Key Features

• Brass construction for corrosion resistance and broad media compatibility
• 2200 psi maximum working pressure rating for high-demand applications
• Compression x MNPT end connections for tubing-to-pipe-thread transitions
• 1/4 inch thread size fits common instrumentation and control line configurations
• 90-degree male elbow geometry for directional routing in tight spaces
• Single-piece quantity suitable for repair, replacement, or new installation work

Compatibility

Designed as an OEM-style replacement or direct-install compression male elbow fitting for systems using 1/4 inch MNPT threaded ports with compression tube connections. Cross-references Swagelok part number B-810-2-4 for equivalency verification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic. Depressurize and isolate the system fully before disassembling any fittings or tubing connections. Compression fittings require proper tube preparation — cut tubing square, deburr the end, and ensure the ferrule seats correctly before tightening. Do not overtighten; follow the fitting manufacturer's standard ferrule-set procedure, typically snugging finger-tight then advancing with a wrench per compression fitting practice.
