Parker 61C-2 Compression Tube Nut 5/16-24 Brass

Product Description

The PARKER 61C-2 is a brass compression tube nut designed to secure compression-style tubing connections in fluid and pneumatic line assemblies. It threads onto a compression fitting body at a 5/16-24 thread size to clamp the ferrule and create a leak-resistant seal without soldering or flaring. Built to SAE J-512 standards, this nut handles working pressures up to 400 psi and operates across a wide temperature range of -65 degrees F to 250 degrees F. Plumbers, HVAC technicians, and refrigeration mechanics use this fitting when assembling or servicing copper or brass tubing runs in both residential and light commercial applications.

This compression tube nut is suited for use in refrigeration lines, fuel systems, hydraulic pilot lines, and general-purpose fluid transfer plumbing where SAE J-512 compression fittings are specified. Its all-brass construction resists corrosion in wet or humid service environments, making it a reliable choice for in-wall plumbing, equipment rooms, and mechanical closets. It is sold individually, with a minimum order quantity of 5 units.

Key Features

• SAE J-512 compliant compression tube nut for standardized fitment
• Brass construction provides corrosion resistance in fluid and refrigerant service
• Rated to 400 psi maximum working pressure
• Wide service temperature range: -65 degrees F to 250 degrees F
• 5/16-24 thread size for precise engagement on matching compression fitting bodies
• No soldering or flaring required for installation

Compatibility

Designed as an OEM-style replacement or service component for compression tube assemblies conforming to SAE J-512 standards with a 5/16-24 thread specification.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or refrigeration mechanics. Depressurize and isolate the tubing line completely before disassembling any compression fitting. Hand-thread the nut onto the fitting body first to avoid cross-threading, then snug with an open-end wrench. Do not overtighten, as brass threads and ferrules can deform under excessive torque.
