Description:
An O-Ring Seal is a type of mechanical seal used to provide a tight and reliable seal between the regulator housing and its components. It is a circular-shaped ring typically made of an elastomeric material, such as rubber, silicone, Viton, and Teflon. O-Ring Seals are designed to fit into a groove in the regulator housing and compress against the components it contacts.

Attributes:
• Maintain their original shape even when compressed over time.
• Can withstand high-pressure conditions and temperatures.

Applications:
An O-Ring Seal is used to prevent leakage of fluids between regulator housing and its components, mostly used in CAT 320D Excavators.
