O-ring 307x5.3 FPM 70 ShA - FKM Viton Fluor Technical Seal

Construction and material

O-ring 307x5.3 FPM 70 ShA is a high performance technical sealing element made from fluorocarbon rubber FPM, also known as FKM or Viton.

This material is engineered for extreme industrial environments where standard elastomers such as NBR or EPDM are not sufficient. FPM provides outstanding resistance to aggressive chemicals, fuels, oils and elevated temperatures.

The hardness of 70 ShA ensures an optimal balance between elasticity and mechanical strength, delivering reliable sealing performance and long service life.

Industrial applications

O-ring 307x5.3 FPM is widely used in chemical processing systems, oil and gas installations, automotive components and heavy industrial machinery.

The large size 307x5.3 mm is typically applied in industrial systems, tanks, pipelines and equipment operating under high pressure and temperature.

FPM O-rings are especially recommended for applications exposed to aggressive media, fuels and hydraulic fluids.
