MS28775-213 - HYDRAULIC O-RING, STATIC, BLACK RUBBER BUTADIENE-ACRYLONITRILE

New, Sold Per Each

Type: Hydraulic O-Ring, Static
A hydraulic O-ring is a circular elastomeric sealing device with a round cross-section, engineered specifically for hydraulic systems to prevent fluid leakage between two joined components. It ensures a reliable seal under high pressure, making it vital for maintaining efficiency and performance in both static and dynamic hydraulic applications.

Lubricate all O-rings before installation, and ensure running seals stay lubricated to prevent wear. Avoid installing O-rings over sharp edges, threads, or cross-drilled ports. AN6227B and AN6230B O-rings are made to MIL-P-25732 specs for use with MIL-0-5606 hydraulic oils. MS28775 O-rings meet MIL-P-5510A specs and perform well with MIL-0-5606 hydraulic fluid up to 160°F.
Standard: Military Standard / MS Standard
MS standards are developed by the U.S. Department of Defense to ensure uniformity and reliability in military and aerospace components, covering a wide range of specifications for fasteners, connectors, and other critical parts.
