Key Features

Food-Safe and Compliant

Formulated to meet FDA standards, our silicone O-rings are non-toxic, odorless, and suitable for direct or incidental contact with food and beverages.

Wide Temperature Range

Maintain reliable sealing from low to high temperatures, ideal for hot-fill, pasteurization, and cold storage processes.

Flexible and Durable

Excellent elasticity ensures tight sealing even under repeated compression. Low compression set and long service life reduce downtime and replacement costs.
