Vertex FC 02: Firm-Grade FKM Seals for High-Heat Oil Service

Vertex FC 02 is a copolymer fluoroelastomer (FKM) compound built for applications where high temperature and oil resistance are critical. With a firmer Shore A hardness than standard FKM grades, this compound holds its shape and sealing force under sustained thermal and mechanical stress, making it a dependable choice for valves, pumps, compressors and automotive systems that demand consistent performance over long duty cycles.

Vertex FC 02 FKM Properties

ISMAT manufactures Vertex FC 02 using premium raw materials and validates every batch through in-house testing to meet strict performance benchmarks. With a Shore A hardness of 80±5, this compound is firmer than our standard FKM grades, giving it an edge in applications where extrusion resistance and dimensional stability matter just as much as chemical resistance.

This higher-hardness FKM suits valves, pumps, compressors and automotive components operating in oil-rich, high-heat environments. Its lower volumetric swell and very good chemical compatibility help extend service life, reducing the frequency of seal replacement and unplanned downtime.

For engineers evaluating sealing materials for tougher mechanical loads alongside thermal and oil exposure, Vertex FC 02 offers a firmer, more robust option within the Vertex FC family. Get in touch with ISMAT to discuss which grade best fits your operating conditions.
