3M 7000118703 Valve Stem Assembly for Orbital Sanders

Product Description

The 3M 7000118703 is a replacement valve stem assembly designed for pneumatic orbital and random orbital sanders. The push-pin style valve opens the air supply when the lever is depressed, controlling airflow to the sander motor. This assembly includes three components: the valve stem pin, an o-ring seal, and a rubber boot dust cover. It is a direct OEM-style replacement intended for use by tool technicians and service professionals performing routine maintenance or repair on 3M pneumatic sanding equipment.

This assembly fits the standard air valve configuration found across the 3M random orbital sander and orbital sander product lines. It is a common wear item replaced during scheduled tool servicing or after air-leak diagnosis. The rubber boot provides dust ingress protection for the valve mechanism, making it suitable for use in production and finishing environments where particulate contamination is a concern.

Key Features

• Push-pin lever-actuated valve stem opens airflow when depressed
• Includes valve stem pin, o-ring, and rubber boot dust cover as a complete assembly
• OEM-style replacement for standard air valve configuration on 3M orbital sanders
• Rubber boot dust cover protects valve internals from particulate contamination
• Sold as individual assembly unit

Compatibility

Designed as an OEM-style replacement for the air valve assembly used in 3M random orbital sanders and orbital sanders equipped with the standard push-pin lever air valve.

Installation Notes

Installation should be performed by a qualified tool technician or service professional. Disconnect the air supply line and depressurize the tool completely before beginning any disassembly. Replace the o-ring carefully to ensure a proper seal and prevent air leaks after reassembly. Inspect the valve bore for wear or debris before installing the new assembly.
