3M 7000000787 Roto Peen Flap Assembly 1x2 in Tc 330

Product Description

The 3M 7000000787 is a Roto Peen Flap Assembly designed for precision peening, surface cleaning, and descaling on metal and other industrial substrates. The assembly measures 1 inch wide by 2 inches in diameter and is built around the TC 330 configuration, making it a compact, portable option for controlled peening operations. It delivers consistent surface treatment without the mess associated with traditional shot or abrasive blasting methods. Licensed HVAC technicians, plumbers, pipefitters, and general maintenance professionals reach for this assembly when preparing pipe ends, fittings, and metal surfaces for bonding, coating, or inspection.

This flap assembly is suited for light to medium industrial and mechanical maintenance applications. It is particularly useful for descaling oxidized pipe surfaces, cleaning weld zones, and conditioning metal prior to coating or sealing. The small 1 inch by 2 inch form factor allows access to tight spaces and confined areas where larger grinding or blasting equipment cannot operate effectively. It is sold individually and is appropriate for both shop use and field service work.

Key Features

• Precision peening action delivers repeatable, controlled surface treatment
• Portable and clean alternative to shot blasting or abrasive media blasting
• Compact 1 inch x 2 inch size for use in confined or hard-to-reach areas
• TC 330 flap configuration for consistent coverage and surface contact
• Effective for descaling, rust removal, and surface preparation on metal substrates

Compatibility

Designed as an OEM-style replacement flap assembly for use with compatible Roto Peen rotary peening systems that accept TC 330 configuration assemblies.

Installation Notes

This assembly is installed by maintenance technicians, pipefitters, and metalworkers using compatible rotary tool or drive systems. Ensure the drive tool is powered off and fully stopped before mounting or removing the flap assembly. Operators should wear appropriate PPE including eye protection and gloves during peening and descaling operations. Follow applicable workplace safety standards and tool manufacturer guidelines for maximum RPM ratings.
