FJC Automotive O-Ring

FJC automotive A/C O-rings are replacement seals for vehicle air conditioning systems. They are also sold as A/C system O-rings or refrigerant line seals. An O-ring is a small donut-shaped gasket. It sits at a connection where hard metal parts meet, such as a line fitting, port or service valve. The seal keeps refrigerant in and keeps moisture and debris out of the closed A/C system.

Key Features:

• High-temperature HNBR (hydrogenated nitrile) construction
• Resists aggressive chemicals and abrasion
• Holds up under heat and oxidation
• Durable material for long service life in A/C systems
• Made by FJC, a manufacturer and distributor of automotive air conditioning parts and service accessories

Replacing worn, dried or cracked O-rings is a common fix for A/C leaks. Choose the correct size and seat the ring properly during installation. A light coat of O-ring lubricant helps the ring seat and helps prevent pinching or cutting.
