TOP Sealing FEP/PFA ENCAPSULATED O-RING
Description:
FEP-/PFA-encapsulated O-rings consist of an elastomer core and a seamlessly closed casing of modified PTFE. The elastomer core made of FKM or VMQ (silicone) guarantees an even pretensioning at the sealing point. The seamless casing is composed of FEP (fluorinated ethylene propylene) or PFA (perfluoroalkoxy-copolymer). It ensures reliable sealing and high resistance to aggressive media. This produces performance similar to that of a PTFE material. Encapsulated O-rings are exclusively used in static applications since movement or abrasive media can destroy the casing. Aggressive chemicals or extreme temperatures can destroy conventional O-rings and will ultimately leads to leakage. FEP-/PFA-encapsulated O-rings can be used wherever an elastomer's chemical resistance is insufficient. Here FEP and PFA materials offer chemical resistance while the elastomer core provides elasticity. Seals made of PTFE are not an option in this case. The material does offer outstanding media resistance, but is not associated with elasticity.
Profiles and dimensions:
Depending on the cross-section diameter, encapsulated O-rings have a lower limit to their inner diameter. If this is taken into account, practically any size can be man manufactured. The most used profile is the circular cross-section. Oval, rectangular and square profiles can be produced on request. Varying cross-sections are possible in both round and angular profiles. Since there are additional tooling costs for elaborate encapsulations, deviations involving small quantities are not always economical. Encapsulated O-rings can basically be offered in all the metric and imperial cross-section thicknesses. Customer-specific solutions can also be realized without difficulty. The minimum manufacturing size of the inner diameter depends on the cross-section thickness of the O-ring. At a cross- section thickness of 1.5 mm, the smallest possible inner diameter works out to 5.3 mm. This is a special size for which a production period of 25 work days must be budgeted. There are no limits on the maximum size of the inner diameter. Since encapsulated O-rings are only slightly extendable and compressible, the installation space must be oriented to these characteristics when diameters are small.
Encapsulated Camlock Gaskets:
Product description:
PTFE FEP Encapsulated Silicone Gasket, FEP Encapsulated VMQ Gasket, PFA Encapsulated Silicone Gasket, Teflon PFA Encapsulated VMQ Gasket. The cross sectional shape of encapsulated gaskets is rectangle or square, material is same as encapsulated o-rings,consist of transparent seamless FEP or PFA shell and VMQ or FKM elastomer core. Encapsulated gasket is mostly used in cam lock couplings, suitable for nearly all chemicals, liquids and gaseous,shows good properties even in the worst conditions. Advantage and standard material choosing, please refer encapsulated o-ring.
