Parker 6-4 Dbz-b Compression Female Elbow 1/4 in Fnpt Brass

Product Description

The PARKER 6-4 DBZ-B is a brass compression-to-female NPT elbow fitting designed for making a 90-degree direction change in instrumentation and fluid system tubing lines. The fitting connects a compression tube end to a 1/4-inch female NPT port, allowing technicians to transition from tubing runs directly into threaded female connections without additional adapters. Rated to 2300 psi maximum working pressure, this fitting is manufactured from brass to ASTM B-124 and BS2872 standards, making it suitable for use in pneumatic and hydraulic instrument lines. HVAC, plumbing, and industrial service technicians install this type of fitting during system assembly and repair.

This elbow fitting is used in residential and light commercial applications wherever a tubing line must turn 90 degrees and terminate into a female-threaded port. Typical scenarios include instrument air lines, refrigeration gauge manifold connections, compressed gas distribution panels, and plumbing supply rough-ins that use compression-style tubing. The 1/4-inch thread size is a common specification across control valves, pressure gauges, and inline instrumentation in HVAC and plumbing systems.

Key Features

• 90-degree elbow body routes tubing in tight spaces without bending the tube
• Compression x FNPT end connections allow direct tubing-to-threaded-port transition
• 2300 psi maximum working pressure suits high-pressure instrumentation service
• Brass construction per ASTM B-124 and BS2872 standards for corrosion resistance and machinability
• 1/4-inch female NPT thread is a widely used standard across HVAC, plumbing, and instrumentation fittings

Compatibility

Designed as an OEM-style compression tube fitting for use in 1/4-inch female NPT threaded ports on instrumentation, pneumatic, and fluid system components. Cross-reference Swagelok part number B-600-8-4 for equivalent specification.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or instrumentation technician. Depressurize and isolate the line fully before removing or installing any compression fitting. Hand-tighten the compression nut onto the tube end, then advance with a wrench per standard compression fitting procedure — do not overtighten, as this can deform the ferrule and compromise the seal. Verify thread sealant or PTFE tape compatibility with the service medium before applying to the FNPT threads.
