Nomaco 200347a Forged Brass Short Flare Nut 1/4 Inch

Product Description

The NOMACO 200347a is a forged brass short flare nut designed to create a gas-tight connection at flared tubing joints. Manufactured to SAE J513 standards, this fitting is forged from brass for consistent thread integrity and leak-free seating at the flare. The short-body profile suits installations where space is limited. At 1/4 inch, it is a common size used in refrigeration, HVAC, and gas line work where reliable flare connections are required. HVAC technicians and plumbers install this fitting as part of flare-joint assemblies on copper or compatible tubing.

This flare nut is used in residential and light commercial applications involving refrigerant lines, gas supply piping, and similar tubing systems requiring a secure, vibration-resistant mechanical joint. The SAE J513 forged short design is standard across HVAC, refrigeration, and propane or natural gas service work. It is appropriate for systems where a full-length flare nut body is not needed or where a lower-profile fitting is preferred at the connection point.

Key Features

• Forged brass construction for consistent thread form and sealing surface integrity
• Short-body design for use in tight or space-constrained installations
• Meets SAE J513 standard for flare fittings
• 1/4 inch size for common refrigerant and gas line applications
• Gas-tight fit when properly assembled with a mating flared tube end

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4 inch flare connections in HVAC, refrigeration, and gas piping systems conforming to SAE J513 flare fitting standards.

Installation Notes

This fitting is installed by licensed HVAC technicians or plumbers. Always depressurize and purge the line before disassembling or making new flare connections. Ensure the tubing end is properly flared using a calibrated flaring tool before seating the nut to avoid leaks. Tighten to hand-snug first, then use a flare nut wrench to final torque — do not over-tighten brass fittings. Follow applicable local codes, IFGC requirements for gas systems, and refrigerant handling regulations where applicable.
