Exceptional sealing solutions for the most challenging food, dairy, and water applications.

Food contact seals

Our sealing specialists are experts in the development and manufacture of chemically resistant food grade O-rings, seals, and gaskets, for use with aggressive media seen in Clean in Place (CIP) and Sterilization in Place (SIP) practices, and high temperature steam.

PPE’s food and dairy material grades have been engineered to provide high performance with excellent mechanical capabilities, combined with thermal and chemical resistance. Elastomers are available in several grades compliant with the requirements of:

Additionally, PPE has pioneered the development of Detectaseal®, a range of metal-detectable elastomers safeguarding against contamination events.

Food grade O-rings

PPE offers a range of food-safe O-rings in elastomer materials compliant with the aforementioned standards.

Elastomer O-Rings

Fully molded elastomer O-rings for critical sealing applications. Standard and custom sizes available.

RJT O-Rings

RJT O-rings are designed to fit RJT hygienic union connectors, and are available in EPDM, NBR, Silicone, FKM, and FFKM grades.

DIN11864 O-Rings

Aseptic O-rings are commonly used in DIN 11866 pipe couplings in a wide range of hygienic processing applications.

Food grade gaskets and seals

PPE is a specialist in high performance food grade gaskets, seals, and custom rubber components, designed specifically for the challenges of food, dairy, and water industries.

HyClamp™ Sanitary Gaskets

HyClamp™ sanitary gaskets provide excellent long-term sealing performance in pipe couplings, delivering almost universal chemical resistance.

HyClamp™ Mini Gaskets

PPE manufactures Hyclamp™ gaskets to DIN32676 in metric and imperial sizes, including a range of mini clamp gaskets.

DIN11851 D-Seals

PPE manufactures elastomer D-seals to fit DIN 11851 fittings, and aseptic pipe couplings including HyClamp sanitary gaskets.

IDF Gaskets

PPE manufactures hygienic connector gaskets for use in IDF (International Dairy Federation) pipe fittings.

SMS Seals (SS 1149)

SMS seals are square section rings typically used in SMS (Swedish Metric Standard) sanitary unions.

Custom Seals

PPE designs and manufactures custom molded rubber parts and bespoke engineered components to meet any sealing requirement.

Potable water seals

PPE has a selection of WRAS approved elastomer materials certified for use in potable water systems.

Our sealing specialists have decades of experience in food grade rubber manufacturing to European Hygienic Equipment Design Group (EHEDG) guidelines. These guidelines look beyond the seal material, and consider the seal in its operating environment. PPE routinely uses Finite Element Analysis (FEA) simulation techniques to develop hygienic seals which do not pose a contamination risk through their potential to ‘trap’ particles or bacteria.

FAQs

An arrangement of white O-rings on a blue background

Food grade gaskets are seal profiles used in food, beverage, and dairy production to prevent contamination and maintain the sterility of consumable products.

They are used in a wide range of process equipment, from blenders and mixers through to packaging machinery.

Materials used in the manufacture of food grade gaskets, like Perlast® at PPE, must comply with a series of strict regulations such as the FDA and USP Class VI.

Perlast perfluorolastomer O-rings

Sealing materials used in food process environments need to be both fit for their intended use, and not pose any health risk to the consumable product.

This means that the sealing material must be resistant to degradation from not only the process media, but also aggressive chemicals and temperatures typical of industrial cleaning regimes.

Food safe seal materials can demonstrate they are fit for purpose through compliance with FDA and USP Class VI regulations.

Food grade O-rings need to demonstrate excellent resistance to high and low temperatures, aggressive chemicals, and rigorous mechanical stresses – while ensuring the total safety of the consumable product.

Depending on the process media, different materials can perform to a high standard, but may have notable weaknesses in other environments.

Perfluoroelastomer (FFKM) material grades – like Perlast® – maintain exceptional sealing effect under all conditions, for total peace of mind in any food production or process environment.
