While O-rings are versatile, specialized applications demand specialized seals. K&G Machinery engineers advanced sealing solutions for your toughest challenges. Flat Gaskets (PTFE, Grafoil®): Ideal for extreme temperatures and highly corrosive media where elastomers fail. Used in our high-temperature series. Lip Seals: Provide superior sealing for powders and granular materials in pneumatic conveying, preventing particle ingress into the groove. Diaphragm Seals: A critical innovation for sterile processing. This seal acts like a valve, ensuring the fluid path is never exposed to the environment during connection/disconnection. Metal-to-Metal Seals: For ultra-high vacuum or extreme pressure applications. Choosing the right seal is as important as choosing the coupling material. Our technical team can guide you to the optimal seal for your specific media and process conditions.
