Precision Polymer Engineering Ltd | Perfluoroelastomer Products | Silicone Rubber Moulders | Specialist Seals

PPE manufactures and supplies CNC machined and fully molded elastomer O-rings from 1.5mm (0.06") to 2.5 metres (8ft) outer diameter. All of the rubber O-rings that we manufacture are available in both small quantities and large volumes.

Standard and non-standard O-ring sizes
We hold a comprehensive range of standard O-ring moulds to BS1806, BS4518, AS568 and ISO3601. For non-standard custom O-rings we can manufacture any size as all our tooling is designed and manufactured in-house using the latest CAD and CNC machine techniques. 

PPE designs and manufactures custom moulded rubber components to customer specifications.  Using the latest elastomer materials and manufacturing techniques, combined with many years experience, PPE can produce custom sealing solutions utilising a variety of shapes and profiles to meet any sealing requirements.

We work closely with our customers to develop solutions that last longer, require less maintenance and deliver the lowest cost of ownership.

The EnDura® range of elite materials has been specifically developed for use in downhole, surface and subsea oilfield equipment and offers explosive decompression (ED) resistance.  The range includes unique material grades that provide the ultimate in chemical resistance, mechanical properties and low/high temperature capabilities for demanding sealing applications.

• EnDura® materials tested to Norsok M-710, Total GS PVV 142 03/01, NACE TM0297 (ED) & TM0187 (Sour Gas) standards.
• Excellent high pressure, high temperature (HPHT) performance upto +327°C (+620°F). 
• Superior low temperature capability from -46°C (-51°F).
• Outstanding chemical resistance to methanol, sour gas (H2S), hot water, steam and oils.
• Excellent mechanical properties provide long-term sealing capability and improved leak prevention thereby minimising equipment failure.

PPE offers a complete sealing systems solution approach. With our technical expertise at your service, we can design complete sealing systems to meet your requirements, utilising a variety of engineering plastics, to produce PEEK and PTFE seals, in addition to high performance elastomer compounds.

With a wide variety of sealing systems to choose from, CNC machined seals are available in numerous standard seal profiles (too many to list here) including Rod Seals, Guiding Elements, Wipers, Rotary Seals, Piston Seals, Stack-Sets, T-seals, Back-up Rings, Bearings, plus custom designed seals. Sealing systems are available in a range of materials, offering the choice of various elastomer compounds, PEEK, or PTFE seals and composite components.

PPE offers the Perlast® range of high performance perfluoroelastomer materials (FFKM).

Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. Perlast® perfluoroelastomer grades provide other properties which prove most valuable in critical sealing applications where purity, high temperatures and retention of sealing force are paramount.

The Perlast® range of perfluoroelastomer materials are at the leading edge of polymer technology. They have been developed to offer superior sealing solutions with enhanced performance and improved functionality, which is proven in the field (see case studies).

Features of Perlast® FFKM seals include:

• High temperature stability up to 327°C (620°F)
• Ulmost universal chemical resistance
• Outstanding mechanical properties
• High purity materials
• FDA, USP Class VI and 3A compliance
• Highest quality parts - quality assured to ISO9001 and AS9100

The latest advance in contamination detection and containment

PPE has worked closely with leading industrial organisations to develop an exciting new range of metal detectable elastomer compounds designed specifically to meet the stringent demands of the pharmaceutical and food processing industries.

The new DETECTASEAL® range includes FDA compliant grades of EPDM, Nitrile, Silicone and Fluorocarbon (FKM) compounds.

Available in blue and black, DETECTASEAL® O-rings have been tested and proven in use at leading pharmaceutical and food manufacturing plants. Fragments of DETECTASEAL® as small as 2mm can be identified by in-line metal detection equipment in process lines.

The HyClamp™ range of hygienic pipe gaskets/seals from PPE is specifically designed to meet the needs of pipe coupling and pipe clamps in food, beverage and pharmaceutical process lines.

Engineered to deliver optimal chemical resistance to meet the requirements of aseptic conditions, CIP (clean-in-place) and SIP (sterilization-in-place) processes, HyClamp™ perfluoroelastomer pipe gaskets/seals provide excellent long-term sealing performance, therefore extending planned maintenance intervals and minimizing downtime.

HyClamp™ perfluoroelastomer seals are manufactured to several size standards of pipe clamps (BS4825, ISO2852 and DIN32676 as lipped or unlipped gaskets) and are supplied with full manufacturing batch traceability and certificates of conformity on request.
