Encapsulated Oring Seal

The encapsulated O-ring is designed for use in special cases such as high temperatures or corrosive conditions.

Encapsulated Orings

Encapsulated orings are special seals designed for use in applications where high temperatures and corrosive conditions make it impossible to use traditional elastomeric rings.

Orings are made up of two parts: an inner rubber core, which provides compression and elasticity, and an outer shell made of Teflon®, which provides high corrosion resistance and thermal stability.

They are widely used in chemical, petrochemical, food and pharmaceutical processes where seals are required for reliable performance in extremely harsh environments.

Encapsulation Options

FEP Encapsulation

Standard material for all applications up to 205°C, resistant to virtually all chemicals and joined by an advanced heat molding process to provide uniform encapsulation.

PFA Encapsulation

Same properties as the FEP encapsulation, but with higher heat resistance for applications above 205°C. Also resistant to virtually all chemicals and bonded perfectly through the advanced heat molding process.

Inner Core / Profile Options

Learn about an Oring's inner cores and the profile options it offers.

Silicone Inner Core

Commercially better material choice combined with lower edge hardness and greater elasticity than Viton®, providing an excellent material choice for most applications.

Viton® Inner Core

Higher chemical resistance than silicone. If the package is damaged, Viton® offers greater resilience to chemical attack.

Hollow Silicone Inner Core

Higher compressibility than solid Silicone core, with a hardness similar to a standard elastomer oring. The hollow core's flexibility means less clamping force is required to enable its sealing abilities. Ideal for fragile applications using sensitive materials such as glass or lightweight plastics. Useful where the sealing area may require room for movement during operation.

Square Core / Silicone Rectangle / Viton®

Designed to be a sealing seal, as opposed to an O-Ring. In particular, the rectangular shape is designed to be a non-contaminating, universal fit Kamlock® hose coupling seal. Eliminates the need to specify different elastomers for different applications and stops coupling leakage due to chemical attack or deformation of a solid PTFE seal.

Benefits of Oring Sealing

Exceptional resistance to agressive chemical products and gas permeability.
Baixo coeficiente de atrito, permitindo menor desgaste do equipamento.
Força de vedação adaptativa de um oring elastomérico.
Greater resistance to compression set compared to unencapsulated orings.
