Parker 61NTA-12 Compression Tube Nut Brass Dot Sae

Product Description

The PARKER 61NTA-12 is a brass compression tube nut designed to create secure, leak-resistant connections in compression fitting assemblies. It threads onto the fitting body to retain the compression sleeve and tube, providing a reliable mechanical seal without soldering or brazing. Rated to 150 psi maximum working pressure, this nut operates across a temperature range of -40 degrees F to 200 degrees F. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it suitable for fluid and pneumatic line applications where compliance is required. The brass construction offers corrosion resistance and compatibility with a wide range of media.

This compression tube nut is used in hydraulic, pneumatic, and fluid transfer line assemblies across HVAC, plumbing, and mobile equipment applications. It is suited for both residential and light commercial installations where compression-style tube fittings are the specified connection method. Licensed plumbers, HVAC technicians, and fleet mechanics commonly use this nut when assembling or servicing copper or compatible tubing runs. The 0.762-inch inside diameter accommodates the corresponding tube size in the Parker compression fitting series.

Compatibility

Designed as an OEM-style replacement or service component for compression fitting assemblies requiring a brass tube nut with a 0.762-inch inside diameter and compliance with D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanic familiar with compression fitting assemblies. Depressurize and isolate the line before disassembly or installation. Hand-tighten the nut onto the fitting body first, then snug with a wrench — do not overtighten, as brass threads can be damaged by excessive torque. Verify the compression sleeve is properly seated on the tube before final tightening.
