-019 BROWN FKM 90D O-RING

Ordered as VB90019, this is an AS568-019 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 0.801 in (20.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.941 in (23.9 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. The compound resists chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across oil and gas, high-temperature process equipment, and semiconductor equipment.

Reference part number VB90019 when ordering; the item is sold individually. Unit weight is approximately 0.3841 g. Review your operating media and conditions against this specification before installation.
