Parker 66CA-6-2 Compression Tube Connector Brass 1/8-27

Product Description

The PARKER 66CA-6-2 is a brass compression tube connector designed to join tubing to female NPT threaded ports in fluid and pneumatic systems. It provides a compression-style connection on one end and a 1/8-27 FNPT connection on the other, creating a reliable, leak-resistant transition between tube and pipe thread. Rated for a maximum working pressure of 1000 psi and a temperature range of -65 degrees F to 250 degrees F, this fitting is suited for demanding service conditions. It measures 1.0 inch in overall length. Licensed plumbers, HVAC technicians, and pipefitters install this type of connector during line assembly or service work.

This fitting is used in residential and commercial applications where copper or other compatible tubing must terminate at a female NPT port. Typical installations include refrigeration lines, pneumatic control circuits, hydraulic instrument lines, and plumbing supply connections. The compression-by-FNPT configuration eliminates the need for solder or flare tooling at the tube end, making it a practical choice for field repairs and new installations alike.

Key Features

• Brass construction provides corrosion resistance and durability in fluid and pneumatic service
• Compression x FNPT end connections allow tool-free tube attachment at one end
• 1/8-27 NPTF thread standard for a pressure-tight mechanical seal
• 1000 psi maximum working pressure rating
• Rated from -65 degrees F to 250 degrees F for broad temperature compatibility
• Compact 1.0-inch overall length suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-install fitting for systems requiring a compression-to-female NPT tube connector with a 1/8-27 thread size.

Installation Notes

Installation is typically performed by a licensed plumber, refrigeration technician, or pipefitter. Depressurize and isolate the system before removing or installing any compression fitting. Hand-tighten the compression nut first, then apply the manufacturer-recommended number of turns with a wrench; do not overtighten, as brass fittings can crack or deform. Verify all connections for leaks after restoring system pressure, following applicable codes such as IPC or IFGC depending on the application.
