Au-ve-co Products 23910 M18 Copper Flat Washer

Product Description

The AU-VE-CO PRODUCTS 23910 is a standard flat washer manufactured from copper, designed for use with M18 metric fasteners. It provides a bearing surface that distributes load, reduces friction, and protects mating surfaces during assembly. The washer measures 20mm inside diameter, 24mm outside diameter, and 1.5mm in thickness. Copper construction offers corrosion resistance and electrical conductivity, making this washer suitable for plumbing, electrical, and HVAC applications where ferrous hardware would corrode or introduce unwanted galvanic interaction. Trades professionals sourcing metric hardware for copper piping connections, bonding applications, or corrosive environments will find this a direct fit for M18 fastener assemblies.

This washer is intended for metric fastener applications across residential and light commercial systems. It is commonly used in plumbing, refrigeration, and mechanical assemblies where M18 hardware is specified and copper material compatibility is required. The metric sizing makes it appropriate for equipment and systems built to international or metric standards. It ships with a minimum order quantity of 25 pieces, suitable for stocking or job-lot purchasing.

Installation Notes

Installation is performed by the applicable licensed trade based on the system being serviced, including plumbers, HVAC technicians, or electricians. De-energize or shut off the relevant system before disassembly or fastener service. Use appropriate metric tools sized for M18 fastener hardware. Avoid mixing copper washers with incompatible metals in environments prone to galvanic corrosion without proper isolation measures.
