Encapsulated O Rings

Product Details:

We are known in the industry for the manufacturing of wide range of FEP & Viton Encapsulated O Rings. Our team of trained professionals enable us to provide a customised range of these products as per the demands of the clients. Elastomeric, rubber O-rings suffer from high friction and limited resistance to aggressive chemicals and gas permeation. Solid Teflon O-rings are rigid with no effective memory and high compression set. Our range of Teflon Encapsulated O-rings combine the resilience and sealing force of an elastomer with the chemical resistance of Teflon. This is accomplished by the use of an elastomeric core of silicone or Viton, with a relatively thin encapsulation of Teflon FEP or PFA polymer. This produces an elastomeric PTFE seal with maximum sealing capability. FEP Encapsulated O-rings are solvent resistant and chemically inert (except for attack by alkaline metals, fluorine and some halogenated compounds at high temperatures) yet have an elastomeric memory near that of rubber O-rings. FEP polymer, also, has an extremely low coefficient of friction (.1 to .2) and very low permeability to gases, making CHEM-RINGS a virtually universal seal for use in hostile environments.

Sizes Available: ID FROM 5.3 MM TO VIRTUALLY ANY SIZE.

CROSS SECTION : 1.5, 1.6, 1.78, 2, 2.4, 2.5, 2.62, 3, 3.15, 3.5, 3.53, 3.8, 4, 4.3, 4.5, 4.75, 5, 5.33, 5.5, 5.7, 6, 6.3, 6.44, 6.5, 7, 7.5, 8, 8.4, 9, 14, 15, 16, 18.

PFA (Perfluoroalkoxy):

• Clear with light blue tint
• Upper temperature limit: 5000F (260)
• Excellent heat and chemical resistance
• Better crack and stress resistance than FEP
• Extremely smooth surface
• Low vapor permeation
• FDA Compliant
• USP Class VI approved

Encapsulation wall thickness ranges from .010"(0.25 mm) to .045" (1.14 mm) depending on the cross section of the elastomeric core.

Features:

• High Chemical Resistance: Chemical attack and swelling are the primary causes of o-ring failure. Encapsulated o-rings are virtually chemically inert.
• Outperforms Solid PTFE O-Rings: Encapsulated o-rings match the chemical and temperature resistance of solid ptfe o-rings, encapsulated o-rings possess properties of elasticity and recovery which are crucial in many sealing applications.
• Economical: Encapsulated o-rings economically and effectively replace kalrez and other exotic o-ring compounds. Encapsulated o-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause premature seal failure.
