Key Features
- Dezincification-resistant brass — resists corrosion in water, gas, and oil service
- Precision machined for repeatable, leak-free connections
- SAE 45° flare — metal-to-metal seal requires no sealant or thread tape
- Resists vibration, thermal cycling, and high-pressure pulsation
- Meets SAE J513; compatible with copper and aluminum refrigerant tubing
- Seals open line ends for pressure testing or future expansion
Common Applications
Used in refrigeration line sets, HVAC equipment connections, natural gas and propane appliance connectors, and high-vibration applications where compression fittings may loosen. The metal-to-metal flare seat is the most vibration-resistant tube connection available.
