Endura V91JF

Recognising the demanding challenges in the oil and gas exploration and extraction industry, PPE have developed the most technically advanced range of elastomer materials to meet the needs of sealing applications operating in the most severe conditions.

The EnDura range of elite materials has been specifically formulated for Rapid Gas Decompression (RGD) resistance in downhole, surface and subsea oilfield equipment.

PPE support enhanced responsible fluoropolymer manufacturing practices and have developed Endura® V91JF as an alternative material to the legacy V91J, by leveraging a new FKM manufacturing process that does not require the use of fluorinated surfactants, thus making the whole production cycle more environmentally sustainable.

EnDura V91JF provides outstanding mechanical strength, excellent overall fluid resistance as well as Rapid Gas Decompression (RGD) resistance.
