Ordered as SV70341, this is an AS568-341 black Viton® (FKM) 70 Shore A Square-Cut Ring supplied with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.895 in (98.93 mm). The square-cut ring provides an economical lathe-cut alternative where a moulded o-ring is not required.
As a material, Viton® (FKM) is specified for excellent resistance to compression set and permeation, outstanding high-temperature capability. Expect good resistance to many acids, chlorinated solvents, and petroleum oils and fuels. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life. The profile itself contributes simple lathe-cut manufacture at low tooling cost and a rectangular section that will not roll in the groove. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.
Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and high-temperature process equipment.
SV70341 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
