Cast Urethane O-Ring AS568 Size 2-019 with 90A Durometer

The Cast Urethane O-Ring AS568 Size 2-019 with 90A Durometer is a high-performance sealing solution designed for demanding industrial applications. Engineered from premium cast urethane material known for its exceptional abrasion resistance and resilience, this o-ring ensures durable sealing even under harsh conditions like fluctuating pressures or exposure to chemicals. Perfect for engineers and technicians seeking precise fitment per military-grade standards, its AS568 Size 2-019 dimensions (ID: 1/2”, OD: 7/8”, thickness: 3/16”) align with critical industry specifications for compatibility with standard hydraulic and pneumatic systems.

With a firm yet flexible 90A durometer rating, this o-ring strikes an optimal balance between compressive sealing force and elasticity—ideal for dynamic environments requiring consistent pressure retention without premature wear. Whether securing hydraulic cylinders in construction machinery or maintaining fluid integrity in automotive assemblies, its durable construction minimizes leaks and extends equipment longevity compared to standard rubber seals prone to swelling or hardening over time.

Designed to outperform competitive offerings through superior chemical resistance (including oils and solvents) and thermal stability up to -40°F to +300°F (-40°C to +150°C), it’s trusted in aerospace components where precision and reliability are non-negotiable. Unlike generic o-rings that fail under cyclic stress or environmental exposure, this engineered seal maintains structural integrity across prolonged use—saving time spent on frequent replacements while reducing costly downtime in critical operations.

Tailored for professionals who demand exact specs coupled with rugged performance, this Cast Urethane O-Ring delivers unmatched value in high-stakes industrial sealing solutions where precision meets durability head-on.
