Product Description

FEP O ring

PTFE FEP PFA Encapsulated Solid Silicone Cord O Ring

Encap o-ring coated with plastic chemical resistance and rubber elasticity, the outer plastic wrap the inner rubber ring, mainly for pumps,valves, pipe flanges, boilers, heat exchangers, gas compressors, Mechanical Seals, Filters, reaction

vessels, pressure vessels, extraction equipment and more.

Outer plastic: Inner rubber:

1.FEP (-20 ~ 200 ℃) 1.Silicone

2.PFA (-20 ~ 260 ℃) 2.FKM / FPM

Specification of Round Flat Silicone O Ring Gasket

1. Duro: 30-90 Shore A

2. Size: Standard,Customized or Samples OEM

PTFE FEP Encapsulated O Rings

O-Ring with a FEP or PFA (PTFE) outer layer encapsulating a Silicone core. The PTFE shell offers excellent chemical and temperature resistance while the Silicone core provides the resiliency needed to provide effective sealing. Readily available in common USA and metric cross-sections and nearly unlimited diameters. FEP encapsulated Solid Silicone with improved chemical resistance up to 205℃. PFA encapsulated Solid Silicone up to 260.

Shore A Hardness:


FKM: 70A

Hollow Silicone: 75-80°A

PTFE coated encapsulated O-rings are designed to combine the sealing properties of the rubber O-ring with the chemical resistance of PTFE. They are generally manufactured from FKM or silicone rubber and are coated in a thin molded layer of PTFE FEP or PFA. This provides a unique seal popular for high friction and aggressive chemical applications. FEP encapsulated O-rings are our most common and are resistant to solvents and chemicals (except for alkaline metals, fluorine and some halogenated compounds at high temperatures). They have a low coefficient of friction and a very low permeability to gases making them suitable for harsh environments. PTFE coated encapsulated o-rings also have a good elastomeric memory.We can also supply rigid PTFE o-rings which have a high compression set.

Perfluoro O-ring perfluoroelastomer seals capability more than 1600 kinds Chemical corrosion, temperature up to 315 ℃, called Kalrez, Japan's Daikin Corporation and the former Soviet Union also developed such products, the rubber has a PTFE heat resistance, chemical stability, the ability of the fluorine solvent everything other than the solvent, the Kalrez seal products processed long-term use at 260-290 ℃. Intermittent use temperature can reach 315 ℃. It is currently the best thermal performance fluorine rubber.
Coated cam lock fittings for rectangle ring, suitable for almost all chemical media, even in the harshest corrosive environments can also be used.
Excellent chemical resistance: FEP / PFA almost all industrial chemicals and solvents are chemically inert, even under high temperature and pressure conditions as well.
Wide temperature range:
-60 ° C to + 205 ° C)
Low friction coefficient: smooth FEP / PFA easier to insert the gasket surface.
Non-stick surface:almost all substances are easy to loose off, easy to clean.
Universal Seal: it can be used to handle almost all the liquid.
Cleaning of: eliminating pollution associated with spring washers.
Benefits of Encapsulated 'O'-Rings and Seals
· Exceptional resistance to aggressive chemicals and gas permeability
· Cost efficient alternative to Kalrez and similar perfluoroelastomer 'O'-Rings
· Low coefficient of friction allowing reduced wear of equipment
· Adaptive sealing force of an elastomeric 'O'-Ring
· Resistant to compression set/cold flow issues of solid 'O'-Rings
Encapsulation Options
· FEP Encapsulation
Standard material for all applications up to 205°C, resistant to virtually all chemicals and joined by an advanced heat moulding process to give a seamless encapsulation.
· PFA Encapsulation
Same properties as FEP encapsulation but with greater heat resistance for applications above 205°C. Also resistant to virtually all chemicals and joined seamlessly via advanced heat moulding process.
Silicone Inner Core Encapsulated o ring
Commercially best material option combined with lower Shore Hardness and greater elasticity than fkm, providing an excellent material choice for the majority of applications.
fkm Inner Core Encapsulated o ring
Greater chemical resistance than Silicone. If encapsulation is damaged, fkm provides greater resilience to chemical attack.
The main advantages :
1, outstanding chemical resistance, suitable for almost all chemical media
2, excellent corrosion resistance
3, the wide range of temperatures applicable
4, good resistance to compression
5, anti-friction
6, good anti-swelling properties
7, high pressure
8. excellent sealing durability, long life
