Part number SV70105 is an AS568-105 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 0.143 in (3.63 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.349 in (8.86 mm). A square-cut ring provides an economical lathe-cut alternative where a moulded o-ring is not required.
As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. It resists chlorinated solvents, aggressive chemicals, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. The profile itself contributes simple lathe-cut manufacture at low tooling cost and greater resistance to extrusion than a round section of the same size. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.
It sees regular use in chemical processing, semiconductor equipment, and high-temperature process equipment.
This item is sold individually under part number SV70105. Nominal inside diameter is listed as 5/32 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
