Encapsulated O Rings
Encapsulated O Rings that are proven to protect the core
M Barnwell Services, the UK’s leading manufacturer, stockist and distributor of Fluid Sealing Products offers a comprehensive range of quality Fluorinated ethylene propylene (Teflon® FEP), PTFE and Perfluoroether (PFA) Encapsulated O Rings.
The design completely encloses a core material and acts as a barrier if any pressure is exerted on the seal. The encapsulated O Ring is widely used across a range of industries, including Food and Drink (FDA), Chemical Processing, Petrochemical, Pharmaceutical, Paints and Dyes, Refrigeration and Cosmetics.
Available in a wide range of standard Metric and Imperial sizes the Encapsulated O Rings can be supplied as small as 4.5mm ID and with no maximum size. M Barnwell Services Encapsulated O Rings are compliant with FDA, ADI-Free, 3A Sanitary Standards, EU Reg. 1935/2004 and USP Class VI.

Fluorinated ethylene propylene (Teflon® FEP), Perfluoroether (PFA), and PTFE.
Silicone and FKM are used as the material for the core of the encapsulated O Ring whilst EPDM is not recommended due to heat-related variations during the production process. FKM and silicone withstand these variations during manufacturing without a decrease in execution.
Silicone core – The silicone core is notably tender than an FKM. It’s also more temperature resistant (great flexibility in both high and low temperatures)
FKM core – FKM attributes great rubber manufacturing qualities. Its outstanding compression set allow it to re-assume to its original form after its deformation
FEP encapsulation – FEP (Fluorinated Ethylene Propylene) provides an O Ring with its immense features regarding its resistance to most games, chemicals and liquids (except liquid alkali metals and various fluorine compounds)
PFA encapsulation – PFA (Perfluoroalkoxy Copolymer) is similar to FEP in its application. It is remarkable due to superior cold flow attributes and improved mechanical features at risen temperatures.
Encapsulated O Rings cannot be manufactured with the same tolerances as standard O Rings. They can deform due to the fluctuating inflexibility of the casino and the core because of temperature impacts.
