RS PRO Nitrile Rubber (NBR) Rotary Shaft Seal, 12 mm ID, 25 mm OD, 7 mm Thickness 229-5229

RS PRO 229-5229 is a high-quality Nitrile Rubber (NBR) Rotary Shaft Seal engineered for reliable sealing performance in industrial and manufacturing settings. Featuring a 12 mm inside diameter, 25 mm outside diameter, and 7 mm thickness, this seal is crafted to provide a long-lasting and robust barrier against fluid and air leaks.

Made from durable nitrile rubber, the seal exhibits excellent resistance to lubrication oils, hydraulic fluids, and grease. Its chemical resistance extends to most hydrocarbons, oils, and fuels, ensuring optimal performance and longevity even in harsh operating conditions. The operating temperature range of -20°C to 90°C makes it suitable for diverse applications including hydraulics, pneumatics, and general mechanical engineering.

This rotary shaft seal is designed for use in pumps, drive belts, and other general engineering applications where reliable sealing is critical for safety and efficiency. It effectively prevents fluid and vapor leakage, protects equipment from contaminants, and maintains system pressure for optimal functionality.

The seal’s versatility is demonstrated by its wide usage in industrial manufacturing, automotive repair, hydraulics, and power transmission technologies. Available in a compact and standardized metric size, it easily integrates into various mechanical assemblies.

The 12 mm ID and 25 mm OD dimensions support precise fitting on rotary shafts. 7 mm thickness enhances sealing strength and durability under operational stress. Nitrile rubber composition ensures chemical and oil resistance for extended seal life.

Wide temperature tolerance supports usage in typical industrial and hydraulic environments.

This seal is part of RS PRO’s range of high-performance O-rings and seals, suitable for rotary and linear movements in mechanical systems. Its robust design and material choice make it ideal for maintaining performance in fluid power and mechanical tool assemblies.
