Copper M8 sealing washers 100 pack

These Zoro Select copper sealing washers suit M8 bolts and come in a pack of one hundred. The annealed copper construction provides reliable sealing for plumbing, automotive and general industrial joints. They are supplied new and ready for immediate use.

8 mm inner 14 mm outer 1.5 mm thick

Each washer has an 8 mm inside diameter and a 14 mm outside diameter with a uniform 1.5 mm thickness. The copper material compresses evenly to seal fluid or gas passages under moderate pressure. The plain finish avoids added coatings that could affect torque readings.

Annealed copper plain finish metric pack

The annealed heat treatment keeps the washers soft enough to conform to flange faces without cracking. Packaged in quantities of one hundred, they support repeated maintenance tasks without frequent reordering. Metric sizing ensures direct compatibility with standard M8 hardware.

Questions about this item

Will the 1.5 mm thickness and M8 fit work with my existing M8 bolts and flanges?

Yes, the washers are made for M8 fasteners with an 8 mm inner diameter, 14 mm outer diameter and a 1.5 mm nominal thickness held to a ±0.2 mm tolerance.

How can I confirm the copper washers are sealing properly once installed?

After torquing the joint, check for any fluid or gas leaks; the annealed copper should deform evenly around the 8 mm bore to create a tight seal.

What comes in the pack and is anything else needed for installation?

The box contains 100 copper sealing washers; no additional components are included, so you only need the matching M8 bolts or studs.
