O RING-210-NTRLE-90 - OTC Tools and Equipment

The OTC Tools and Equipment 12550 O RING-210-NTRLE-90 is a high-performance sealing solution engineered for demanding automotive and industrial applications. This professional-grade O-ring, crafted from 90 durometer Nitrile (Buna-N) rubber, is designed to provide reliable, leak-free seals in systems exposed to petroleum-based fluids and high pressures. It delivers enhanced durability and extrusion resistance, crucial for maintaining system integrity in challenging operational environments.

Key Features

• Premium Nitrile (Buna-N) Construction: Manufactured from Nitrile rubber, known for excellent resistance to petroleum products, oils, fuels, and hydraulic fluids.
• 90 Shore A Durometer Hardness: A harder compound (90 Shore A) specifically designed for high-pressure systems, offering superior resistance to extrusion and deformation compared to softer O-rings.
• Optimal Temperature Range: Performs effectively across a wide temperature spectrum, typically from -40°F to +250°F (-40°C to +121°C), ensuring reliability in various thermal conditions.
• Enhanced Durability: Provides improved resistance to abrasion, mechanical wear, and repeated compression cycles, extending service life in dynamic and demanding assemblies.
• Standard AS568-210 Size: Conforms to AS568-210 dimensions, featuring an Inside Diameter (ID) of 0.734 inches (18.64 mm) and a Cross Section (CS) of 0.139 inches (3.53 mm), ensuring compatibility with standard grooves.

Applications

This OTC Tools O-ring is an essential component for professional technicians and mechanics requiring robust seals in critical systems. It is ideally suited for high-pressure hydraulic and pneumatic applications, including pumps, valve assemblies, and hydraulic fittings where extrusion and deformation are a concern. Its strong resistance to oils and fuels makes it perfect for various automotive components, such as engine oil systems, fuel lines, and gearbox assemblies. Additionally, its durability extends its utility to industrial machinery, compressors, and heavy equipment where reliable sealing under stress is paramount.
