Jb Industries 61-4 Compression Nut 0.25 Inch

Product Description

The JB INDUSTRIES 61-4 is a 1/4 inch compression nut used to create secure, leak-free connections in refrigeration and HVAC tubing assemblies. Compression nuts thread onto fittings to compress a ferrule against tubing, providing a reliable mechanical seal without soldering. This type of fastener is a standard component in refrigerant line sets, gauge manifold hoses, and service valve connections. HVAC technicians and refrigeration mechanics reach for compression nuts when working on systems that require a removable, reusable connection point that holds pressure without brazing.

This compression nut is suited for use in residential and light commercial HVAC and refrigeration applications wherever 1/4 inch tubing connections are required. It is commonly used during system service, component replacement, and line set installation. The 1/4 inch size is a widely used dimension in refrigerant circuit work and fits standard copper and compatible tubing used throughout the trade.

Key Features

• 1/4 inch compression fitting size for standard HVAC and refrigeration tubing
• Creates a secure, reusable mechanical seal without soldering or brazing
• Compatible with standard compression ferrules and fittings
• Designed for refrigerant line and service connection applications

Compatibility

Designed as a standard OEM-style replacement compression nut for 1/4 inch tubing used in residential and light commercial HVAC and refrigeration systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or refrigeration mechanics. Always recover refrigerant and depressurize the system before disconnecting or replacing compression fittings. Hand-tighten the nut onto the fitting before applying a wrench to avoid cross-threading. Follow all applicable EPA Section 608 refrigerant handling requirements during any service work involving refrigerant circuits.
