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.

High performance materials
With an unrivalled range of elastomer materials available, PPE has an elastomer for every application, with performance characteristics that meet high temperature, high pressure and aggressive chemical applications.

For O-rings used in food, dairy and pharmaceutical applications PPE offers a variety of elastomer material grades compliant with many international requirements such as FDA, USP Class VI, WRAS, KTW and 3-A in addition to metal detectable O-rings, all of which are free from Animal Derived Ingredients.

For non-standard O-ring seals we can produce bespoke tooling very quickly (92% of O-ring tools are produced same day) providing cost effective solutions and a responsive service.

Pre-formed 'shaped' rubber O-rings are used to assist assembly and prevent unnecessary stresses being placed upon the seals. Such rubber O-rings are often used for rectangular path door seals or to navigate around pipe-work. By removing permanent stresses from the O-ring, PPE pre-formed O-rings can extend the life of the part in your application.

Jointed rubber O-rings - PPE offers the largest fully moulded, formed elastomer O-rings manufactured on a single tool, in one pressing operation. However, for O-rings larger than 2.5m (8ft) in diameter, lengths of cord can be joined to produce O-rings of limitless size.
