Benefits & Applications

This EPDM flange gasket creates a dependable seal that reduces leaks and maintenance downtime. Its flexibility compensates for minor flange irregularities, improving sealing performance and making installation straightforward. Typical applications include municipal and industrial water and wastewater systems, HVAC systems, pumping systems, and food & beverage processing where resistance to cleaning chemicals and sanitary performance are important. By preventing leaks and corrosion at flange joints, the AF300G helps lower operational costs and extend system life.

Installation & Maintenance

For best results: clean flange faces before installation, align flanges carefully, and tighten bolts in a star pattern to the manufacturer’s recommended torque. Avoid over‑compressing the gasket to preserve elasticity and sealing ability. Inspect gaskets periodically and replace them if you see cracking, deformation, or chemical degradation.
