Parker 66NTA-10-6 Compression Tube Connector 3/8 Inch Fnpt

Product Description

The PARKER 66NTA-10-6 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 fitting on one end and a 3/8 inch FNPT connection on the other, providing a secure, leak-resistant joint without soldering or special tools. Rated to 150 psi maximum working pressure and capable of handling temperatures from -40 degrees F to 200 degrees F, this fitting suits a wide range of service conditions. Licensed plumbers, HVAC technicians, and refrigeration technicians typically install this fitting in copper or compatible tubing runs where a threaded female port transition is required.

This connector is suited for use in residential and light commercial plumbing, HVAC, and refrigeration piping systems where a compression-to-female NPT interface is needed. It transitions tubing into threaded female ports on valves, manifolds, gauges, or equipment panels. The brass construction resists corrosion in water, oil, and many common service fluids. With a 0.398 inch inside diameter, it accommodates standard tubing sizes appropriate for 3/8 inch connections.

Key Features

• Compression x FNPT end connections allow tool-free tubing installation on the compression side
• 3/8 inch NPTF thread standard for reliable threaded port sealing
• 150 psi maximum working pressure rating for typical plumbing and HVAC service
• Operating temperature range of -40 degrees F to 200 degrees F
• Brass construction provides corrosion resistance across a broad range of fluids
• 0.398 inch inside diameter maintains consistent flow through the fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for plumbing, HVAC, and fluid distribution systems requiring a compression-to-3/8 inch female NPT threaded connection in brass.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and IPC or IFGC guidelines. Shut off the fluid or gas supply and depressurize the line completely before disconnecting any existing fittings. Hand-tighten the compression nut before applying a wrench, and avoid overtightening, which can deform the compression ferrule and cause leaks. Inspect the connection for leaks at operating pressure before returning the system to service.
