Parker 61NTA-10 Compression Tube Nut Brass 5/8 Inch Od

Product Description

The PARKER 61NTA-10 is a brass compression tube nut designed to create secure, leak-free connections in compressed air, hydraulic, and fluid transfer lines. It threads onto a compression fitting body to retain the tube and ferrule during assembly, producing a reliable mechanical seal without welding or soldering. Rated to 150 psi maximum working pressure and compatible with 5/8-inch outside diameter tubing, this nut meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards. Brass construction provides corrosion resistance and durability across a wide temperature range of -40 to 200 degrees F. Plumbers, HVAC technicians, and fluid-system mechanics install this fitting in both mobile and stationary applications.

The 61NTA-10 is suited for use in hydraulic brake lines, pneumatic systems, fuel lines, and general fluid-conveyance assemblies where DOT and SAE compliance is required. It is commonly installed in commercial vehicle brake systems, industrial plumbing runs, and HVAC refrigerant or fluid-line connections. The 5/8-inch OD tube size makes it a practical choice for medium-bore line assemblies in both residential and light commercial service environments.

Compatibility

Designed as an OEM-style compression tube nut for 5/8-inch OD tubing assemblies requiring DOT and SAE-compliant fittings in fluid and pneumatic line systems.

Installation Notes

Licensed plumbers and qualified fluid-systems technicians should install this fitting. Depressurize and drain the line fully before disassembly or replacement. Hand-tighten the nut onto the fitting body first, then use an appropriately sized open-end wrench to complete the connection; avoid over-tightening, which can damage the ferrule or tube. Installations on vehicle brake systems must comply with applicable D.O.T. and SAE requirements.
