Parker 169CA-8-4 Compression Male Elbow Brass 1/4-18

Product Description

The PARKER 169CA-8-4 is a brass compression tube male elbow fitting designed to connect a compression tube line to a male NPTF threaded port at a 90-degree angle. The fitting uses a 1/4-18 thread size conforming to the NPTF thread standard, ensuring a pressure-tight mechanical seal without the need for sealant tape in many applications. Rated to 750 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this elbow suits demanding fluid and pneumatic system service. Plumbers, HVAC technicians, and industrial pipefitters install this fitting in tight-space routing situations where a straight connection is not practical.

This fitting is suited for residential and light commercial plumbing, refrigeration, pneumatic, and hydraulic lines where a direction change from a compression tube to an NPTF-threaded male port is required. Its brass construction provides corrosion resistance compatible with water, air, and a wide range of fluid media. The compression end accepts standard tubing and creates a leak-free connection through mechanical compression of the ferrule against the tube OD. Typical install scenarios include instrument lines, control system tubing, and utility plumbing panels.

Key Features

• Brass construction for corrosion resistance across a broad range of media
• Maximum working pressure of 750 psi for reliable service in pneumatic and hydraulic lines
• Wide service temperature range: -65 degrees F to 250 degrees F
• 1/4-18 NPTF thread standard for a pressure-tight seal at the male port connection
• Compression x MNPT end connections for tool-accessible, no-solder installation
• 90-degree elbow configuration for routing in confined or offset spaces

Compatibility

Designed as an OEM-style replacement or new-installation compression tube male elbow for systems requiring a 1/4-18 NPTF male threaded port and a standard compression tube connection in brass construction.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system fully before disassembling any existing fittings or installing this elbow. Verify that the mating threaded port conforms to NPTF specifications and that the compression tubing OD matches the fitting size before assembly. Hand-tighten the compression nut first, then apply the manufacturer-specified additional turns with a wrench to seat the ferrule without over-tightening.
