Parker 66C-10-8 Compression Tube Connector 1/2-14 Brass

Product Description

The PARKER 66C-10-8 is a brass compression tube connector designed to join a compression tube end to a female National Pipe Taper Fitting (FNPT) port. Built to SAE J-512 standards, it delivers a reliable, leak-resistant mechanical connection in fluid and pneumatic systems. The fitting handles a maximum working pressure of 150 psi and operates across a wide temperature range of -65 degrees F to 250 degrees F. It is a single-piece, reusable fitting typically installed by plumbers, HVAC technicians, and pipefitters in light industrial, commercial, and mechanical system applications.

This connector is suited for use in hydraulic, pneumatic, and general fluid transfer lines where a compression-to-FNPT transition is required. Common install scenarios include connecting tubing runs to threaded ports on valves, manifolds, pumps, and instrumentation panels. The 1/2-14 NPTF thread standard ensures a pressure-tight seal at the pipe thread connection without relying solely on thread sealant. It is a practical choice for both new installations and retrofit work in tight spaces where a dependable threaded-compression transition is needed.

Key Features

• SAE J-512 compliant construction for standardized performance and interchangeability
• Brass material provides corrosion resistance suitable for water, air, and compatible fluid media
• Compression x FNPT end connections allow direct transition from tubing to female threaded ports
• Rated to 150 psi maximum working pressure for light industrial and mechanical system use
• Wide service temperature range from -65 degrees F to 250 degrees F
• 1/2-14 NPTF thread standard supports a pressure-tight seal at the threaded connection

Compatibility

Designed as an OEM-style compression-to-FNPT connector for use in plumbing, HVAC, and light industrial fluid or pneumatic systems where SAE J-512 compression fittings and NPTF female threaded ports are specified.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Shut off and depressurize the system fully before removing or installing any fittings. Use an appropriate thread sealant or PTFE tape on the NPTF male threads per the system manufacturer's recommendation and applicable plumbing codes. Do not overtighten the compression nut, as brass fittings can deform if excessive force is applied.
