568-345 FKM 75 SQUARE CUT RINGS

SV70345 is an AS568-345 black Viton® (FKM) 70 Shore A square profile Quad-Ring built to an inside diameter of 3.975 in (100.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.395 in (111.63 mm). In service, this quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is valued for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The compound resists aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or hot water and steam will shorten service life.

Typical settings include chemical processing, oil and gas, and aerospace.

Order part number SV70345, sold individually. Nominal inside diameter is listed as 4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
