Why use Food Grade?

The unique properties of rubber as a strong yet flexible material lead to its widespread use in food processing. Rubber polymers are used for seals, gaskets, hoses and conveyor belts.

Variables such as the fat content of the food, time, temperature and the extent of contact between food and rubber can cause chemicals from the rubber to leach in to the food. Lubricants for machine parts and equipment can carbonise or burn, react with steam or caustic cleaners.

Food Grade Seals

FDA compliant Kalrez® parts offer the food and beverage industries a new level of sealing against process contamination, leaching and seal failure. Kalrez® combines thermal and chemical performance with a rubber like sealing ability. View case study.

Fluid seals also distributes DuPont™ Krytox® NSF certified H-1 and H-2 oils and greases. NSF H-1 compliance means they may be used wherever there is a potential exposure of the lubricated part to food. Krytox® Food Grade lubricants are serviceable at continuous temperatures between –60° and 300° C. They are completely odourless and tasteless.
