Parker 66NTA-10-8 Compression Tube Connector 1/2 in Brass

Product Description

The PARKER 66NTA-10-8 is a brass compression tube connector designed to join tubing to female NPT threaded ports in fluid and gas distribution systems. It features a compression inlet on one end and a 1/2-inch NPTF female threaded outlet on the other, creating a reliable, leak-resistant mechanical connection without soldering or brazing. Rated to 150 psi maximum working pressure and suitable for service from -40 degrees F to 200 degrees F, this connector suits a wide range of hydraulic, pneumatic, and process piping applications. Licensed plumbers, HVAC technicians, and fluid-systems mechanics are the typical installers.

This connector is well suited for residential and light commercial installations where tubing must terminate or transition to a female NPT threaded fitting. Common applications include instrumentation lines, fuel systems, refrigeration accessory lines, compressed air distribution, and water service connections. The compression-by-FNPT configuration makes it a practical choice wherever a tubing run meets a pipe-threaded port on valves, gauges, or manifolds. The 0.398-inch inside diameter supports consistent flow through the fitting body.

Key Features

• Compression x FNPT end connections allow tubing-to-pipe-thread transitions without soldering
• 1/2-inch NPTF thread standard ensures pressure-tight engagement with compatible female ports
• 150 psi maximum working pressure rated for demanding service environments
• Operating temperature range of -40 degrees F to 200 degrees F covers most HVAC and plumbing applications
• Brass construction provides corrosion resistance and durability in fluid and gas service
• 0.398-inch inside diameter supports adequate flow capacity through the connector body

Compatibility

Designed as a standard compression-to-FNPT connector for use with compatible tubing and 1/2-inch NPTF female-threaded ports on valves, gauges, manifolds, and similar components in fluid and gas piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC or instrumentation technician. Shut off and depressurize the system completely before removing or installing any fitting. Ensure tubing is cut square and deburred before inserting into the compression end, and confirm that the female NPT port threads are clean and in good condition before engagement. Follow applicable local codes, including IPC and IFGC requirements, for the specific service type.
