Metal Gaskets, Metallic & Semi-Metallic

Metal and semi-metallic gaskets are designed to withstand extreme temperatures, pressures and chemical exposure. Available in standard and custom configurations, these rugged metal gaskets are made of a wide range of materials to accommodate all types of process applications.

A semi-metallic gasket is a composite gasket, which consists of both non-metallic and metallic materials. The metal generally provides the strength and resilience of the gasket. These gasket types are suitable for both low and high temperature / pressure applications. A wide range of materials are available.

We supply and manufacture gaskets, joints and rings from materials including copper, mild and Stainless steel, brass, Monel, Soft Iron, Titanium, Carbon Steel, Nickel, Hastelloy, Inconel and Incoloy. We also offer machined metal components.

Our facilities enable us to manufacture metallic shims to suit your requirements. No matter how simple or complex the components and no matter the quantity required PTM supply all industry’s with metal shims for applications including Pump shim sets, gearbox packings etc.

A wide range of Taylor rings, washers and RTJ’s (Ring Type Joints) are also available from stock.

Our years’ of experience in the sealing industry coupled with the lastest manufacturing equipment mean we can supply your bespoke or off the shelf metallic seals quickly and competitively.

Below we highlight the main styles of metal and semi-metallic gaskets that we manufature and supply.

Spiral Wound Gaskets

Spiral wound gaskets are widely used in many industries to seal a vast array of media across a wide range of temperatures and pressures. The key to the gaskets versatility is the inherently resilient sealing element.

Metal Shim Sets

We manufacture metal shims in a wide range of materials and thicknesses, with parts offered as thin as 0.05mm (0.002 ”). If you require individual shims or as a shim set comprising of different thicknesses, we can supply. Shims can be manufactured to your drawing or specified dimensions.

Metal Jacketed/Clad Gaskets

The most basic type of semi-metallic gasket has a compressible insert enclosed within a metallic jacket. The insert material forces the metal to deform to suit the flange surface and effect a seal.

Metal Eyelet Gaskets

Eyelet gaskets offer protection against blowout. In addition to our range of PTFE envelope gaskets, we offer a range of metal eyelet and envelope gaskets in materials such as stainless steel, soft iron, copper, brass, Monel and titanium. Please contact us with your requirement.

Data Sheet

Machined Rings/Washers

From a simple laser cut copper or stainless steel washer to a more complex CNC machined ring, we offer a wide range of solutions in materials ranging from mild steel to high temperature Inconel and Hastelloy. Please contact us with your requirement.

Data Sheet

Dowty/Bonded Seals

Our Bonded Seals (or Dowty Seals) consist of a rubber sealing element that is bonded to the inner wall of a metal washer. They are commonly used in applications where high pressures demand greater sealing capacity than can be obtained with Copper or other metallic washers.

Data Sheet

Corrugated Metal Gaskets

There are a wide variety of corrugated metal gaskets which are used as a versatile seal when bolt loads are low. The are comprised of concentric grooves on both sides and can be coated with other materials to make a seal on distorted or uneven faces. We stock a range of gaskets from leading worldwide manufacturers.

Data Sheet

Camprofile/Kammprofile Gaskets

Camprofile/Kammprofile gaskets are used in many older seals since they have both a flexible nature and reliable performance. Camprofiles work by having a solid corrugated core with a flexible covering layer. We stock a wide range of Garlock and Flexitallic Kammprofile gaskets.

As with all materials, we are happy to advise on any application, but final responsibility lies with the customer.
