Zoro Select M32 Copper Sealing Washers

This pack contains ten annealed copper sealing washers sized for M32 fasteners. Each washer has a 32 mm inside diameter, a 40 mm outside diameter and a uniform 2 mm thickness with a ±0.2 mm tolerance. The plain finish provides a soft, malleable sealing surface for threaded connections. Supplied in a small pack of ten pieces.

Who should use these washers

They suit maintenance and assembly work where a copper crush washer is specified for M32 threads, such as hydraulic fittings, pipe unions or equipment flanges. The annealed temper allows the washer to deform and seal under torque. Buyers who need a different bolt size, a non-metallic seal or a larger quantity per pack should look elsewhere.

Critical specification: M32 fit and 2 mm thickness

The washer is made for M32 screw size with a 32 mm bore and 40 mm outer diameter. Thickness is fixed at 2 mm with a ±0.2 mm tolerance, so the joint design must accommodate this exact dimension. Copper material and annealed heat treatment give the required compressibility for a reliable seal.

Questions about this item

What is included in the pack and do I need any additional fixings?

How do I confirm these are the right size for my application?

Match the washer to an M32 thread; the inside diameter is 32 mm, the outside diameter is 40 mm and the thickness is 2 mm with a tolerance of +/- 0.2 mm.

What does the copper material mean for sealing performance once installed?

The annealed copper crushes under torque to form a reliable metal-to-metal seal that resists heat and corrosion in hydraulic or automotive systems.
