Why Replace Your Flare Adapter?

• Worn Threads – Difficulty achieving leak-free connections
• Damaged Flare Seat – Compromised sealing surface
• Nitrogen Leaks – Escaping nitrogen at connection point
• Cross-Threading – Damaged threads from improper installation
• Preventive Maintenance – Replace before failure occurs

1/4" Flare Connection:

The 1/4" flare is the standard connection size for HVAC/R nitrogen leak testing and pressurisation. This adapter provides a secure, leak-free connection between the nitrogen regulator and standard 1/4" flare hoses used in refrigeration service work.

Installation:

Ensure threads are clean and free from debris. Thread the flare adapter carefully to avoid cross-threading. Tighten to manufacturer's specifications. The flare seat must be clean and undamaged for proper sealing. Refer to the nitrogen regulator repairable parts breakdown diagram for proper assembly.
