Mi-t-m 25-0639 O-ring 12mm X 1mm

Product Description

The MI-T-M 25-0639 is a replacement O-ring measuring 12 millimeters in outer diameter with a 1 millimeter cross-section. O-rings of this type form a pressure-tight seal between mating surfaces in fluid or air circuits. This seal is commonly found in pressure washer pump assemblies, valves, and fittings where preventing water or chemical leakage is critical to system performance. Service technicians and maintenance professionals install this part during routine pump rebuilds, seal kit replacements, or any time a damaged or degraded ring is identified during inspection.

This O-ring is suited for use in MI-T-M pressure washing equipment and compatible power cleaning accessories. It is a direct-fit replacement intended to restore proper sealing function in pump heads, unloader valves, chemical injectors, and related fluid-handling components. The small profile makes it a common service item stocked alongside other seal and O-ring assortments for field repair work.

Key Features

• 12mm outer diameter with 1mm cross-section for precise fitment in MI-T-M equipment

Installation Notes

This part is typically installed by service technicians during pump overhaul or seal replacement procedures. Before servicing, shut off and depressurize the unit completely and disconnect the water supply. Inspect the mating groove for debris or damage before seating the new O-ring. Avoid over-stretching the ring during installation, as deformation can compromise the seal.
