MS Pressure Relief Grease Fittings are manufactured to meet Military (MIL-SPEC) Standards, which require detailed performance testing, extensive documentation, sampling, dimensional checks and traceability of materials. Commonly used on gear box housings and bearings, where excessive lubricant pressures are not desirable. These safety valves open at pre-determined pressures shown in the table below and can be used with either oil or grease.
