Parker 68CA-6-8 Compression Tube Connector Brass

Product Description

The PARKER 68CA-6-8 is a brass compression tube connector designed to join compression tubing to a male NPT threaded port in fluid and pneumatic systems. It features a 1/2-14 NPTF thread on the male end and a compression-style tube connection on the opposite end, making it suitable for leak-free line connections in hydraulic, pneumatic, and fluid transfer applications. Rated to a maximum working pressure of 1000 psi and a temperature range of -65 to 250 degrees F, this fitting is built for reliable performance in demanding service environments. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this type of connector.

This connector is suited for residential and commercial installations where a compression tube must terminate or transition at an NPTF-threaded port. Common applications include hydraulic lines, compressed air systems, refrigeration tubing connections, and instrumentation plumbing. The brass construction resists corrosion and is compatible with a wide range of fluid media. Its compact body fits into tight installations where space around fittings is limited.

Key Features

• Brass construction for corrosion resistance and durability
• Compression x MNPT end connections for tool-assisted leak-free joints
• 1/2-14 NPTF thread standard for pressure-tight sealing without additional sealant tape in many applications
• 1000 psi maximum working pressure for demanding fluid and pneumatic service
• Wide temperature range: -65 to 250 degrees F

Compatibility

Designed as an OEM-style compression-to-MNPT fitting for use in fluid, pneumatic, and refrigeration systems requiring a 1/2-14 NPTF male thread and a compression tube end connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician familiar with compression fittings and NPT thread standards. Depressurize and isolate the line completely before disassembling or installing any fitting. Apply thread sealant or tape as required by the applicable code and the fluid media being conveyed. Do not overtighten the compression nut, as over-compression can damage the ferrule and compromise the seal.
