Hygienic clamp gaskets

USP Class VI clamp gaskets manufactured in EPDM and silicone elastomers specifically formulated for biopharmaceutical applications.

  • Biopharmaceutical
  • FDA compliant material
  • Tested and certificated to USP Class VI
  • Compatible with CIP, SIP and WFI systems
  • Low intrusion
  • Exceptionally low extractables
  • ASME BPE Compliant

The Elast-O-Pure range of materials has been developed from first principles to meet the specific requirements of the bioprocessing sector.

Our highly controlled manufacturing process, with fully documented chain of custody, provides a reduced risk of failure due to consistent product quality and full traceability of the raw ingredients.

Our range of hygienic clamp gaskets is available in two high performance materials, Elast-O-Pure EP75B EPDM elastomer and Elast-O-Pure SIL70 VMQ silicone.

Our Elast-O-Pure EP75B material offers 50% lower Total Organic Carbon (TOC) extractables than typical EPDMs used in this application, thereby minimising potential product contamination.

In addition, low adhesion to stainless steel, even after thermal cycling, avoids potential equipment damage and offers an easy, quick change-out.

  • Biocompatibility tested via USP Class VI <87> and <88>
  • Engineered compatibility with common cleaning materials, process fluids and steam
  • Extremely low compression set (~6%) for long-term seal stress retention without retightening
  • Low intrusion provides predictable 'cleanability' throughout seal life
  • Formulae are free of Animal Derived Ingredients (ADI)
  • Longer service life offers extended preventative maintenance cycles

In addition to the features provided by our Elast-O-Pure materials, all our hygienic clamp gaskets offer the following benefits:

  • Long service life for best value and lowest total cost of ownership (TCO) in operation.
  • Sizes available from 1/2" to 12".
  • Full batch traceability - with elastomer compounding and gasket moulding undertaken in house by James Walker.

Supplied in size ranges including:

  • BS4825 part 3, 1991
  • BS4825 Non-Standard
  • BS Schedule 5 Pipe
  • BS Schedule 40
  • ISO 2852
  • ISO 1127
  • ISO 2037
  • Mini Series Ultra Bore

Custom sizes can be manufactured to order.
