Metal endcap seals

Rubber to metal bonded seal for wellheads.

  • Wellheads

Our metal endcap seals are hybrid metal / elastomer products with a high level of the extrusion resistance necessary for high pressure casing and tubing applications. We have a long history of successfully designing these seals for ISO 10423 F.1.11 (pressure and thermal cycling) accreditation.

These products are often custom designed and manufactured to suit specific wellhead sealing environments and are available in a range of sections, sizes and materials.

Metal end caps are chemically bonded to an element of high performance elastomer. The elastomer element energises the system for efficient sealing, whilst intimate metal-to-metal contact is maintained between the end cap and the sealing surface.

End caps provide extrusion resistance and support for the elastomeric element.

Metal end cap seals are available in a range of elastomers suitable for the most arduous oil and gas environments.

HNBR elastomers: Elast-O-Lion 101 and Vermilion Seven or Elast-O-Lion 985 and Vermilion Five, all these grades are well proven for toughness, wear resistance, rapid gas decompression resistance and a broad temperature capability.

Elast-O-Lion 101 and Vermilion Seven are robust, rapid gas decompression resistant materials, whilst Elast-O-Lion 985 and Vermilion Five are proven for use in very low temperature applications and also exhibit good rapid gas decompression resistance.

FKM elastomers: available options include FR25/90, Vermilion Two, Vermilion Three, and Vermilion Four. These materials offer RGD resistance, extrusion resistance, good mechanical properties and the typically excellent chemical resistance associated with FKM elastomers.

Metal components are typically manufactured in stainless steel or nickel alloys for corrosion resistance.
