There have been lots of changes in the materials and technologies of manufacturing O-rings and sealing kits. Such is the latest creation, PFA or FEP encapsulated O-ring. It merges the brilliant chemical and wear resistance of PTFE O-rings and the great elasticity of an elastomer.
These encapsulated O-rings are a great choice, since they possess the elastic capacity of seals and are better resistant than elastomers. A2Z Seals has brought forth an exclusive collection of O-rings with AJAX Seals that are long lasting and performance-oriented. Considering the numerous applications where traditional elastomers have failed, these encapsulated range of O-rings have been introduced. They are a great foil to conventional O-rings. PFA and FEP materials make for great resistant to chemical damages. Even PTFE seals are unable to provide lasting media resistance and good elasticity at the same time.
Here are some benefits of encapsulated O-rings-
- Outstanding resistance power against almost all media (except some fluorine substances and alkali metals)
- Comes to use in various applications in extreme temperatures
- Suitable for pharmaceutical, food and chemical industries
- Low chances of contamination
- Low permeation
- Goes with FDA materials
- Highly performance-oriented, cost-effective seals for various critical applications
Despite the use of encapsulated O-rings in multitude of applications, there are some restrictions to them. They are as follows-
- Do not use them in dynamic applications
- Do not bring them in close contact with abrasive media
- Do not put them under high pressure
- Do not use them when they are too elongated
If you remember these things while using encapsulated O-rings, they will last longer and perform better than normal sealing tools.
Availability in multiple sizes, shapes and designs
Based on the cross-section diameter, these encapsulated O-rings come with a lower limit to their inner diameter. However, if this is taken care of, then these O-rings can be made in any size, shape and design.
Cross-section is the most sought-after designs used for encapsulated O-rings. But rectangular, oval and square designs can also be tailor-made as per request.
