Mi-t-m 25-0609 O-ring Inlet Valve Seal

Product Description

The MI-T-M 25-0609 is a G 55 O-ring designed to seal the first-stage inlet valve on MI-T-M pressure washing equipment. This small-diameter elastomeric ring creates a leak-free barrier between the inlet valve body and adjoining pump components, preventing water bypass and maintaining system pressure integrity. It is a direct-fit replacement part installed during pump rebuilds, routine seal maintenance, or after identifying a weeping inlet connection. Service technicians and pump repair shops handling MI-T-M equipment keep this seal on hand as part of standard pump overhaul kits.

This O-ring fits the first inlet valve position in MI-T-M pressure washer pump assemblies. It is suited for residential and light commercial pressure washing units where the inlet valve assembly requires seal replacement due to wear, cracking, or loss of compression. When a pump shows signs of internal bypass, reduced output pressure, or visible weeping at the inlet manifold, replacing this seal is a standard first step in the diagnostic and repair process.

Key Features

• G 55 O-ring profile sized for the first-stage inlet valve position
• Restores seal integrity at the pump inlet valve to maintain operating pressure
• OEM-specified replacement part for MI-T-M pump service
• Compact form factor simplifies installation during pump disassembly

Compatibility

Designed as an OEM-style replacement seal for the first inlet valve position in MI-T-M pressure washer pump assemblies.

Installation Notes

Installation is typically performed by a pressure washer service technician during pump rebuild or valve service. Before beginning work, relieve all system pressure, shut off the water supply, and disconnect power to the unit. Inspect the valve seat and surrounding bore for scoring or damage before installing the new O-ring, and apply a compatible lubricant to the ring to ease seating and prevent tearing during reassembly.
