Sanitary Tri-Clamp Silicone Gasket - Premium Hygienic Seal
Sanitary Tri-Clamp silicone gaskets are engineered sealing solutions for hygienic process connections. Produced from purified, food-grade silicone compounds, these gaskets form contamination-resistant seals for Tri-Clamp ferrules used across food, beverage, pharmaceutical, and biotech industries.
2. Product Overview
Designed for frequent sterilization and rigorous cleaning cycles, our silicone Tri-Clamp gaskets combine excellent elastic recovery with a smooth, non-porous surface finish. They deliver consistent sealing performance and minimize microbial harborage points in sanitary piping networks.
3. Features
3.1 Superior sanitary properties
- Non-porous, easy-to-sanitize surface that reduces contamination risk.
3.2 Wide thermal tolerance
- Performs reliably during high-temperature sterilization and low-temperature processes.
3.3 Durable elasticity
- High compression set resistance and consistent recovery after repeated clamping.
3.4 Chemical and steam resistance
- Compatible with common CIP/SIP detergents, alcohols and mild acids used in sanitary cleaning.
3.5 Food-contact safe
Formulated to meet food-contact regulations and to minimize extractables.
3.6 Low-friction finish
Smooth geometry simplifies assembly and reduces wear on mating stainless-steel ferrules.
