Parker 66NTA-6-2 Compression Tube Connector 1/8 Inch Fnpt

Product Description

The PARKER 66NTA-6-2 is a brass compression tube connector designed to join tubing to female NPT threaded ports in fluid and pneumatic line assemblies. It features a compression end on one side and a 1/8 inch FNPT end on the other, creating a secure, leak-resistant connection without soldering or flaring. Rated to 150 psi maximum working pressure and suitable for temperatures from -40 degrees F to 200 degrees F, this fitting is built for demanding service environments. The brass construction offers good corrosion resistance and is compliant with D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards. Licensed HVAC technicians, plumbers, and fluid system technicians regularly specify this fitting in refrigeration, pneumatic, and hydraulic tubing runs.

The 66NTA-6-2 is suited for residential and light commercial applications where compression-to-FNPT transitions are required. Typical installations include refrigeration line sets, pneumatic control tubing, and hydraulic brake or fluid lines where D.O.T. and SAE compliance is required. The 0.217 inch inside diameter accommodates standard small-bore tubing sizes common in control and instrument lines. This connector is appropriate for use wherever a reliable mechanical tube connection to a female NPT port is needed in a code-compliant assembly.

Key Features

• Compression x FNPT end connections allow tool-accessible, no-solder tube-to-port transitions
• Brass construction provides corrosion resistance in fluid and pneumatic service
• 150 psi maximum working pressure for reliable performance in pressurized lines
• Wide temperature range of -40 degrees F to 200 degrees F suits diverse operating conditions
• Compliant with D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards
• 1/8 inch NPTF thread size with 0.217 inch inside diameter

Compatibility

Designed as an OEM-style compression tube connector for small-bore tubing assemblies requiring a 1/8 inch FNPT port connection in fluid, pneumatic, or refrigeration line applications meeting D.O.T. and SAE specifications.

Installation Notes

Installation should be performed by a qualified technician familiar with compression fittings and NPT thread standards. Depressurize and isolate the line completely before disassembly or installation. Compression fittings require proper tube squareness and full insertion into the fitting body before tightening the compression nut; overtightening can deform the ferrule and compromise the seal. Thread connections should be made in accordance with NPTF sealing practices without relying solely on thread sealant tape.
