Food, Dairy & Water Elastomer Seals
Precision Polymer Engineering (PPE) understands the exacting requirements sealing materials must meet in the food and dairy sectors. We specialize in chemically resistant food grade rubber seals for use with aggressive media seen in Clean in Place (CIP) and Steam in Place (SIP) practices and high temperature steam sterilization.
PPE's food and dairy material grades have been specially developed to provide high performance food grade seals with excellent mechanical capabilities and chemical resistance. Elastomer materials are available in several grades compliant with the requirements of the:
- Food and Drug Administration (FDA) - EPDM, HNBR, NBR, Silicone, FKM, FFKM
- United States Pharmacopeia (USP Class VI) - EPDM, Silicone, FKM, FFKM
- 3A 18-03 Sanitary Standards (3A) - EPDM, HNBR, NBR, Silicone, FKM, FFKM
- EC Regulations 1935/2004 and 2023/2006 - NBR, EPDM, Silicone, HNBR, FKM, FFKM
- WRAS (BS 6920) potable water - EPDM, Silicone
In addition, PPE has pioneered the development of Detectaseal®, a range of innovative metal detectable elastomers.
Food grade O-rings
PPE offers a range of O-rings in elastomer materials that are compliant with the aforementioned standards:
PPE food grade rubber components for the Food, Dairy & Water industries also include:
- HyClamp sanitary gaskets
- DIN11851 D-seals
- IDF seals
- SMS 1149 seals
- Specialist inflatable seals
- Custom rubber seals
Manufacturers of process equipment can extend the operating capability of their original equipment without expensive component redesigns. Lower overall cost of ownership can be achieved through a combination of increased seal life and reduced process downtime.

Potable water seals
In addition to food grade elastomers, PPE also offers WRAS approved elastomer materials that have been certified for use in potable water systems.
PPE has over 30 years' experience in food grade rubber manufacturing to the 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.
With food and pharmaceutical sealing, materials need to demonstrate a broad chemical compatibility profile, high temperature resistance, abrasion resistance and the capability to withstand aggressive cleaning regimes. Precision Polymer Engineering molds components from materials which are certified and compliant with various industry standards, including FDA, 3A Sanitary Standard 18-03, WRAS, EC1935-2004 and EC2023-2006.
Unique sealing challenges and solutions
Across an extensive product range of high performance seals, PPE can engineer a sealing solution tailored to the precise nature of your own problem. Working collaboratively with customers, our engineers can design custom parts and sealing solutions to satisfy requirements specific to food and pharmaceutical applications, optimizing your operations and safeguarding your consumers.
Food, Dairy & Water Approvals
The US Food & Drug Administration (FDA) provides guidance for elastomer sealing components used in food contact environments.
3A Sanitary Standard 18-03 defines specifications and best practice for the design, manufacture, installation and use of elastomer seals in hygienic dairy equipment.
EC Regulations EC1935/2004 and EC2023/2006 of the European Parliament and Council are directives that covering elastomer materials intended to come into contact with food.
Elastomer sealing materials approved for drinking water applications in the United Kingdom must satisfy the requirement of BS 6920 of the Water Regulations Advisory Scheme.
