Diversitech DIVEDNS4-8 Short Flare Nut 1/2 Inch Forged Brass

Product Description

The DIVERSITECH DIVEDNS4-8 is a 1/2-inch nominal short flare nut machined from forged brass for use in refrigerant and HVAC line-set connections. Forged brass construction provides high impact strength and resistance to mechanical shock and vibration, making it suitable for applications where connection integrity must hold under system stress. The short profile suits tight-clearance installations where a standard-length flare nut would not fit. This fitting is domestically manufactured and intended for installation by licensed HVAC and refrigeration technicians working on copper refrigerant line sets.

This short flare nut is used in residential and light commercial HVAC and refrigeration systems where 1/2-inch flare connections are required. Typical applications include connecting copper refrigerant lines to evaporator coils, condensing units, and service valves. The short body style is particularly useful in confined spaces such as equipment cabinets and line-set terminations where standard flare nuts create clearance issues.

Key Features

• Forged brass construction for high impact strength and vibration resistance
• Short-body profile for installations with limited clearance
• 1/2-inch nominal flare end style for standard copper refrigerant line connections
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or service fitting for 1/2-inch flare connections in residential and light commercial HVAC and refrigeration systems.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Recover and isolate refrigerant from the system before disassembling any flare connections, in accordance with EPA Section 608 regulations. Inspect the flare seat on the mating fitting for damage before torquing the nut. Use a calibrated torque wrench sized for flare fittings and follow the system manufacturer's torque specifications.
