What is an O-Ring?

A circular gasket that seals between the Camlock adapter and coupler, preventing leaks.

O-Ring Materials

• NBR (Nitrile): Oil-resistant
• EPDM: Ideal for water and chemicals
• Viton: High heat and chemical resistance
• PTFE: Extreme chemical durability

Choosing the Right O-Ring

• Match with fluid type, temperature, and system pressure

Signs of O-Ring Failure

• Cracks, brittleness, flattening, swelling

Replacement Steps

1. Remove worn O-ring
2. Clean groove
3. Insert new O-ring without twisting
4. Lightly lubricate if necessary
