A Metal Gasket

Metal Shims & Washers

Metal Shim washers are used to make height adjustments, prevent leaks, and eliminate unnecessary movement between machine parts to help prolong equipment lifetime.

Composition and physical specification are key factors when selecting a shim, with their ability to withstand cryogenic temperatures as low as -250°C (Copper, Stainless Steel 321 & 347, Nickel) and extreme temperatures up to 950°C (Inconel) making them ideal for a wide range of applications.

We are vastly experienced gasket manufacturers and can produce bespoke metal shims and washers in a wide range of popular standard materials including Copper, Brass, and Stainless Steel, or specialist metal alloys including Monel, Hastelloy and Inconel.

Metal Shims

Metal Shims

Commonly used to align the spacing, height and levels between components, metal shims can be precision-manufactured in a range of square and rectangular configurations.

Metal Washers

Metal Washers

Flat metal washers are used for leak protection, sealing, and pressure distribution across numerous applications and can be manufactured to any size and depth in a wide range of materials.

Bonded Washers

Bonded Washers

Bonded or sealing washers often include a rubber or neoprene backing for a stronger seal in conditions where metal corrosion may be an issue, such as in areas exposed to liquids.

Custom Shims

Custom Shims

We precision manufacture custom shim washers in both long and short runs to suit requirements. From simple bespoke washers to complex multi-faceted shims in specialist materials.

The Manufacture of Metal Shims

With over 50 years of experience in gasket manufacture and material conversion, shims can be precision-cut in a range of thicknesses, shapes and sizes to suit customer requirements at our base in West Yorkshire. 

Our turnkey gasket manufacturing service encompasses CAD gasket design, prototyping and worldwide distribution, and is a popular choice with clients. Utilising state-of-the-art jet and laser cutters alongside tried and tested techniques, our skilled team manufacture high-quality gaskets in compliance with recognised national and international standards.

Shim and Washer Selection

Highly resistant to chemicals and corrosion, Metal Shims and washers can be utilised across a wide range of applications, from the motor vehicle industry to marine environments and processing plants. For example, it is common to use Stainless Steel shims in steam processes due to their ability to operate effectively at high temperatures and pressures.
