-329 BROWN FKM 90D O-RING

APG stocks the VB90329, an AS568-329 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. It resists many acids, aromatic hydrocarbons, and aggressive chemicals. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across oil and gas, aerospace, and semiconductor equipment.

This item is sold individually under part number VB90329. Unit weight is approximately 8.7625 g and nominal inside diameter is listed as 2 inch.
