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

Product Description

The PARKER 8-4 DBZ-SS is a compression tube female elbow fitting designed to connect tubing to a female NPT-threaded port at a 90-degree angle. Constructed from stainless steel to ASTM-B-124 and BS2872 standards, this fitting handles working pressures up to 6300 psi, making it well-suited for high-pressure instrumentation, process, and fluid-system applications. The compression end seats against the tube OD for a leak-tight connection without welding or flaring. Plumbers, pipefitters, and instrumentation technicians install this fitting in systems requiring a reliable direction change from tubing to a female threaded port.

This fitting is used in residential and commercial applications where compression tubing must transition to a female NPT-threaded component. Typical scenarios include instrumentation lines, hydraulic pilot lines, pneumatic control circuits, and process fluid systems. The stainless steel construction resists corrosion in wet, chemical, and outdoor environments. The 1/4 inch thread size suits smaller-diameter tubing runs common in control and sensing circuits.

Key Features

• Stainless steel construction meets ASTM-B-124 and BS2872 material standards
• Maximum working pressure rated to 6300 psi for high-pressure service
• Compression x FNPT end connections allow tool-free tube insertion with standard ferrule and nut assembly
• 1/4 inch FPT thread for direct connection to female NPT ports
• 90-degree elbow geometry for routing tubing in tight or directional installations

Compatibility

Designed as an OEM-style compression fitting for use in instrumentation, process, and fluid-system applications requiring a compression-to-female-NPT transition at 1/4 inch thread size.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician familiar with compression fitting assembly. Shut off and depressurize the system completely before removing or installing any fitting. Follow the manufacturer ferrule and nut seating procedure; do not overtighten, as stainless compression fittings require a specific turn-past-finger-tight method per fitting manufacturer guidelines. Verify thread engagement and check for leaks before returning the system to service.
