Food, Dairy & Water
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), United States Pharmacopeia (USP Class VI), 3A 18-03 Sanitary Standards (3A) and EC Regulations 1935/2004 and 2023/2006. In addition, PPE has pioneered the development of Detectaseal®, a range of innovative metal detectable elastomers.
PPE food grade rubber components for the Food and Dairy industry include:
- Standard and non-standard sized O-rings
- RJT O-rings
- IDF seals
- DIN11851 D-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.

Products for Food, Dairy & Water
Below is a selection of the most common products we supply to the Food, Dairy and Water industry. Visit the Products page to see the full range.
Custom Rubber Seals
PPE designs and manufactures custom molded rubber parts and bespoke engineered components in infinite shapes and profiles to meet any sealing requirements.
With a specialist elastomer for every sealing application, our engineers can identify an elastomer O-ring to perform perfectly in your operating environment.
HyClamp Sanitary Gaskets
Sanitary gasket seals for pipe couplings used in food, beverage and pharmaceutical process lines in FDA, USP, 3A & metal detectable elastomer materials.
T-seals comprise of an elastomer T-shaped cross section and two backup rings, offering an excellent sealing solution for static or dynamic applications.
An elastomer L-shaped cross section using a single backup ring for use in static or dynamic, single direction pressure applications, where high gland fill may be a concern with T-seals.
Energized lip seals provide a versatile sealing system for uni-directional pressure applications in either static or reciprocating dynamic conditions, in rod or piston grooves.
Wiper Seals - Scraper Seals
Wiper seals (scraper seals) provide a physical barrier to limit the ingress of moisture, dirt and other contaminants from piston rods used in hydraulic systems into the primary sealing system.
