Caterpillar Seal O-ring | 1090072

Description

The 1090072 seal/O-ring is a valuable component with a wide range of applications. Designed as a standard seal/O-ring type, it is constructed from durable rubber material, providing reliable sealing performance. Its impressive temperature range of -40° F to 275° F makes it suitable for various conditions. This seal/O-ring finds use in applications like automotive, air conditioner seals, high-temperature flex boot seals, power steering, hydraulic seals and more. Notably, it is compatible with substances such as diesel fuels, diester lubricants, ozone and water-based engine coolants, while being incompatible with certain fluids like aromatic and oxygenated gasolines and brake fluids. With a dash size of 326, a cross-section diameter of 0.21 inches, inside diameter of 1.6 inches and an outside diameter of 2.02 inches, it offers a reliable sealing solution. Its HNBR (78) material description highlights its resistance to fuel, oils and abrasion, while the PTFE coating enhances its longevity and ease of assembly. The seal/O-ring is color-coded orange for easy identification.
