Product Description

The 5x8x2.5 O-Ring (Motor Shaft Seal 5x8x2.5) is a compact oil-resistant sealing solution designed for motor shafts, featuring 5mm inner diameter, 8mm outer diameter, and 2.5mm thickness. Crafted from durable oil-resistant elastomer, it operates across -40°C to +120°C withstanding industrial oils and lubricants. This 5x8x2.5 Oil Resistant Seal provides reliable leak prevention for rotating components in automotive, machinery, and industrial equipment. Key advantages include wear resistance, compression recovery, and compatibility with dynamic motion, though prolonged exposure to aggressive chemicals may degrade performance. Its precise dimensions ensure tight shaft sealing without auxiliary connections, ideal for compact motor assemblies requiring maintenance-free operation in demanding environments.
