757,943.375,30 excl. VAT

HITEC® FKM O-rings are reliable sealings for applications that require very good ozone, weather and aging resistance, that need to resist harsh conditions and/or exposure to various chemicals. Fluorocarbon elastomers have excellent resistance to oils, aliphatic carbon hydrides, hardly inflammable hydraulic liquids, fuels and other organic solvents and chemicals.

These HITEC® FKM O-rings are typically used in fuel systems, hydraulics, high vacuum systems and other applications where reliability, conformity and approvals are a prerequisite.

The cross section (cord diameter) of this O-ring is 6.99 mm (imperial: 0.275 inch). Please select the AS568/BS1806 size identification number and/or internal diameter to find the right O-rings for your application.

Description

HITEC® FKM* O-rings are reliable sealings for applications that require very good ozone, weather and aging resistance, that need to resist harsh conditions and/or exposure to various chemicals. Fluorocarbon elastomers have excellent resistance to oils, aliphatic carbon hydrides, hardly inflammable hydraulic liquids, fuels and other organic solvents and chemicals. These HITEC FKM O-rings are typically used in fuel systems, hydraulics, high vacuum systems and other applications where reliability, conformity and approvals are a prerequisite.

AS568 is the size standard for O-rings from the Society of Automotive Engineers (SAE). It specifies the inside diameters, cross-sections, tolerances, and size identification numbers for O-rings used in sealing applications. The British Standard BS1806 was issued by the British Standards Institution as an O-ring size guide. It lists all imperial standard sizes and includes the 5 main cross section groups in AS568 plus other “intermediate” sizes. BS1806 has been superseded by ISO-3601, but is still widely used as a cross reference for the identification and selection of O-rings.

The cross section (cord diameter) of this O-ring is 6.99 mm (imperial: 0.275 inch). Please select the AS568/BS1806 size identification number and/or internal diameter to find the right O-rings for your application.

The price specified is per set of 100 O-rings. Please contact us if you need large quantities.

*) Please note that the abbreviation FKM is used as the category for fluoroelastomers according to the American standard ASTM. The international abbreviation according to DIN/ISO is FPM.
