Parker 61VL-12 Brass Compression Tube Nut 3/4 in Od

Product Description

The PARKER 61VL-12 is a brass compression tube nut designed to secure compression-style tube connections in fluid and pneumatic systems. It mates with a 3/4-inch outside diameter tube and uses a 1-1/8-18 straight thread configuration conforming to NPTF thread standards. Rated for service from -30 degrees F to 135 degrees C, this nut handles a wide range of operating temperatures found in industrial and mechanical installations. Licensed plumbers, pipefitters, and hydraulic system technicians typically install this hardware when assembling or servicing compression fittings in high-pressure or fluid-transfer lines.

This tube nut is suited for use in hydraulic, pneumatic, and fluid-transfer assemblies where compression-style end connections are specified. It is appropriate for both industrial and commercial applications requiring a leak-resistant mechanical tube joint. The brass construction provides good corrosion resistance in water, oil, and many common fluid media. Installers working on mobile equipment, machine tool plumbing, or plant piping systems will find this nut compatible with standard compression fitting bodies designed to ISO 6149 and SAE J1926 specifications.

Key Features

• Brass construction for corrosion resistance in fluid and pneumatic service
• Fits 3/4-inch outside diameter tubing
• 1-1/8-18 straight thread for precise, leak-resistant engagement
• Meets ISO 6149 and SAE J1926 standards
• NPTF thread standard for reliable sealing
• Wide temperature range: -30 degrees F to 135 degrees C

Compatibility

Designed for use with compression fitting bodies accepting a 3/4-inch OD tube and a 1-1/8-18 straight thread nut, conforming to ISO 6149 and SAE J1926 standards.

Installation Notes

Installation is performed by licensed pipefitters, hydraulic technicians, or plumbers following applicable system codes. Depressurize and isolate the line completely before disassembling or replacing any compression fitting hardware. Hand-tighten the nut onto the fitting body before applying final torque with the appropriate open-end or flare-nut wrench to avoid cross-threading the brass threads. Inspect the compression sleeve and tube end for damage before reassembly.
