Custom Ring Gaskets & Seals

Ring gaskets form a sealed joint between two mating surfaces, preventing leaks of oils, coolants, water, and compressed gases across a wide temperature and pressure range. These simple, durable seals work in static applications where the gasket remains compressed between flanges without rotation or movement.
