Parker 12-12 Cbz-b Compression Male Elbow 3/4 in Brass

Product Description

The PARKER 12-12 CBZ-B is a brass compression tube male elbow fitting designed to connect 3/4-inch outside diameter tubing to a male NPT threaded port at a 90-degree angle. Manufactured to ASTM-B-124 and BS2872 standards, this fitting is rated for a maximum working pressure of 1900 psi, making it suitable for demanding fluid and gas distribution systems. The compression-style connection eliminates the need for soldering or flaring, allowing for reliable, leak-resistant joints in a wide range of trade applications. Licensed plumbers, HVAC technicians, and industrial pipefitters are the typical installers.

This elbow fitting is used in residential and commercial plumbing, HVAC refrigerant and compressed air lines, instrumentation, and hydraulic systems where a directional change from tubing to a threaded port is required. The compression-by-MNPT configuration makes it a common choice for connecting copper or compatible hard tubing runs to valves, manifolds, and equipment with NPT-threaded inlets or outlets. Its brass construction provides corrosion resistance suited to water, air, and many compatible fluid media.

Key Features

• Brass construction conforming to ASTM-B-124 and BS2872 standards for material integrity
• Maximum working pressure of 1900 psi for high-pressure service
• 3/4-inch tube outside diameter compression inlet with male NPT threaded outlet
• 90-degree elbow configuration for directional tubing changes in tight spaces
• No soldering or flaring required — compression fitting simplifies installation and maintenance
• Swagelok cross-reference part number B-1210-2-12 for sourcing reference

Compatibility

Designed as an OEM-style replacement and standard compression fitting for use with 3/4-inch outside diameter hard tubing and NPT-threaded ports in plumbing, HVAC, compressed air, and instrumentation piping systems.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes, including IPC and IFGC guidelines where relevant. Depressurize and isolate the line before disassembly or installation of any compression fitting. Hand-tighten the compression nut onto the fitting body before applying the appropriate number of additional turns with a wrench to seat the ferrule — consult the fitting manufacturer torque guidance for the specific tubing material and wall thickness. Do not overtighten, as this can deform the ferrule and compromise the seal.
