Encapsulated O-ring Fep Silicon / Viton® - Pfa Silicon / Viton®

Encapsulated O-rings are consisting of an inner core elastomer perfectly coated with FEP or PFA fluoropolymer. Basically the two types of products differ for a different resistance to temperature and abrasion. The inner core is Viton® or Silicone. They are used where is required a high chemical resistance and purity product.

Used in industries::
• Chemical.
• Petrochemical.
• Food.
• Pharmaceutical.

Encapsulated O-rings are available in sections from 1.78 mm to 25.4 mm. The only size limitations are for small diameters.

FEP operating temperature:
• FEP / Silicon: -60 ° C to + 200 ° C
• FEP / Viton®: -20 ° C to + 200 ° C

PFA operating temperature::
• PFA / Silicon: -60 ° C to + 260 ° C • PFA / Viton®: -20 ° C to + 200 ° C
this type of O-ring provides a greater resistance to abrasion.
