Why consider encapsulated o-ring

Encapsulated O-rings are recommended which they are chemically resistant and used to prevent the corrosive fluids or gasses from getting through to the elastomer in an application.

Encapusulated O-rings have excellent resistance to almost all types of media. They worked in a wide temperature range and made from FDA approved materials to suit food and drugs processing applications.

Types of encapsulated O-rings

Two types of cores are available, which enables them to be used in different application.

1. Solid Core

These are standard which usually made of either a silicone energiser ore or a core made from Viton.

Viton cores have excellent elasticity.

Sillicode has similar benefit but because of softer core, it has higher standard of heat resistance. Therefore it is recommended to use in lower temperature application.

2. Hollow Core

For fragile applications where extreme elasticity is required, it is best to use Viton and silicone cores.

Although they may come with a compromise in terms of compression set and recovery.

Outer Jackets

1. PFA Outer Jackets

Excellent at resisting a range of corrosive chemicals.

Compression set is low, and their operating temperatures range from -60°C to +260°

Compared to FEP, they have higher mechanical strength and improved resistance to cracking and stress.

2. FEP Outer Jackets

Compared to PFA, slightly weaker mechanically.

Narrower operating temperature range, of -60°C up to +205°

Their service life is slightly shorter, but they are generally lower cost.

PTFE Encapsulated O-Rings ( Teflon O-Rings )

The PTFE O-Rings for use in applications which require a chemically resistant and non-compressible material. PTFE is the chemically inert of the O-ring materials.

  1. Teflon Encapsulated Viton O-Ring

  2. Teflon Encapsulated Silicone O-Ring

They are generally manufactured from Viton or Silicone core and are coated in a thin moulded layer of Teflon FEP or PFA.

Teflon encapsulated O-Rings are primarily used as a static seal (axial or radial).

Benefit

  • Very good resistance to nearly almost all types of media

  • Applications in broad range of temperatures

  • Non-contaminating material make it superbly suited for use in the food, chemical and pharmaceutical industries

  • Non contamination

  • Low permeation

  • Low coefficient of friction prevents the stick-slip effect

  • FDA-compliant

  • Cost-effective, high-performance seal for many critical application areas

Common Applications

FEP and PFA Teflon shell delivers excellent chemical resistance with the energizing resiliency of a rubber elastomer core combines the best of both materials for o-rings with extreme chemical and temperature resistance.
