The M83248/1-012 O-Ring is a precision elastomer sealing component manufactured to military specification M83248. It is supplied in a pack of 100 pieces and used in aircraft hydraulic, pneumatic, fuel, and lubrication systems to ensure reliable sealing performance.

This O-ring is designed for consistent performance under pressure, temperature variation, and exposure to aviation fluids, maintaining elasticity and sealing integrity over long service life.

Its primary functions include:

Providing pressure-tight sealing in aircraft systems
Preventing fluid or gas leakage in hydraulic and pneumatic applications
Maintaining elasticity under thermal and pressure cycling

M83248 O-rings like the -012 size are critical safety components in aviation, ensuring system reliability and preventing leaks that could affect aircraft operation or safety.
