Parker 8-4 Dbz-b Compression Female Elbow 1/4 in Fnpt

Product Description

The PARKER 8-4 DBZ-B is a brass compression tube female elbow fitting designed to connect tubing to a female NPT threaded port at a 90-degree angle. The compression end grips and seals the tube mechanically without soldering or flaring, while the FNPT end threads into a female-tapped port or valve body. Built from brass, this fitting handles a maximum working pressure of 2200 psi, making it well-suited for hydraulic, pneumatic, refrigeration, and instrumentation lines where a reliable, leak-resistant elbow connection is required. Plumbers, HVAC technicians, and instrumentation specialists routinely specify this fitting type for tight-space routing where a straight fitting will not work.

This fitting is appropriate for residential and commercial applications involving copper or compatible tubing connected to female NPT ports. Typical install scenarios include instrument tubing runs, refrigerant accessory lines, compressed air systems, and hydraulic control circuits where a directional change is needed at a threaded port. The 1/4 inch thread size suits small-diameter tubing and porting common in control and instrumentation work.

Key Features

• 90-degree female elbow routes tubing in space-constrained installations
• Compression x FNPT end connections eliminate the need for soldering or flaring
• Brass construction provides corrosion resistance and broad fluid compatibility
• 2200 psi maximum working pressure rated for demanding service conditions
• 1/4 inch FPT thread standard for compatibility with common NPT-tapped ports

Compatibility

Designed as an OEM-style compression tube female elbow fitting for use in plumbing, HVAC, pneumatic, and instrumentation systems requiring a 1/4 inch FNPT connection with a compression tube inlet.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation specialist. Depressurize and isolate the system completely before disassembling any fittings or connections. Hand-tighten the compression nut onto the tube, then advance with a wrench per standard compression fitting practice; do not overtighten, as this can deform the ferrule and compromise the seal. Verify that the tubing is cut cleanly and seated fully before torquing the compression nut.
