Parker 4-8 Cbz-b Compression Male Elbow 1/2 in Brass

Product Description

The PARKER 4-8 CBZ-B is a brass compression tube male elbow fitting designed to connect tubing to a male NPT threaded port at a 90-degree angle. Constructed from brass, this fitting accepts a compression-style tube connection on one end and terminates in a 1/2-inch male pipe thread (MNPT) on the other. It is rated for a maximum working pressure of 3500 psi, making it suitable for demanding fluid and gas distribution applications. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting in both commercial and residential systems where a reliable, leak-resistant tube-to-pipe transition is required.

This male elbow fitting is used in hydraulic lines, pneumatic systems, fuel supply lines, and instrumentation tubing runs where a direction change from tubing to a threaded pipe port is needed. The compression-by-MNPT configuration suits installations involving copper or compatible metal tubing terminating at valves, manifolds, bulkheads, or equipment ports with 1/2-inch NPT female threads. It is appropriate for both new construction and retrofit service work.

Key Features

• Brass construction provides corrosion resistance and compatibility with a wide range of fluid media
• 3500 psi maximum working pressure rating suits high-pressure hydraulic and pneumatic applications
• Compression x MNPT end connections allow tubing to transition directly to a male pipe thread port
• 1/2-inch thread size on the MNPT end conforms to MPT thread standard
• 90-degree elbow geometry simplifies routing in tight or angled installation spaces
• Single-piece package quantity allows individual replacement or repair purchases

Compatibility

Designed as an OEM-style replacement or direct-install compression tube male elbow for systems using 1/2-inch MNPT connections with compression-style tubing. Cross-references with Swagelok part number B-400-2-8 for sourcing verification purposes.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and the IFGC or IPC as relevant to the system type. Depressurize and isolate the line completely before disassembly or fitting installation. Ensure tubing is cut cleanly and squared before inserting into the compression end to achieve a proper seal. Do not over-tighten the compression nut; follow standard trade practice for the tubing material and size in use.
