Long Design

Featuring an extended barrel configuration, this 1/4 inch (6.35mm) long-design aluminum flare nut offers enhanced thread engagement and superior grip for high-vibration HVAC applications. The extended length provides extra structural support right behind the flare, safeguarding the copper tube against cracking or stress fracture under continuous compressor operation. Ideal for tight service spaces and critical liquid lines, it guarantees a robust, long-lasting mechanical seal for refrigeration systems.
