The Gasket & Joint Sealing Experts

One of the advantages you’ll benefit from when working with Cotter Marketing Ltd., is the amount of exposure the company has had, initially in the many aspects of the shipping industry, and then, as time moved on, in land-based industries. For sealing solutions, you need look no further than Cotter Marketing, for the experience, the expertise, the quality of the products from top manufacturers, and the technological guidance you may need for your sealing and packing solutions. Specifically, the listings below offer you an extensive selection of gaskets and joint sealing products.

Gaskets are produced from a number of different materials, both metallic, and non-metallic. Asbestos was used for many years because of its fire- and heat-resistant characteristics, but this has ceased because of the toxic nature of the material. Today, gaskets are produced from a number of different materials, or from a combination of materials. These include graphite, different types of rubber, silicone, cork, paper, stainless steel, polyester, and nylon. This is where the Cotter Marketing Solutions Team comes into the picture. We are ready to advise and to prepare solutions for you. Different gaskets suit different applications.

For your gasket requirements – benefits of Partnerships with Cotter Marketing

Frequently Asked Questions

What is the difference between a gasket and a mechanical seal?

Gaskets and seals are both designed to prevent leaks, but the two products perform somewhat differently. Mechanical seals function in rotating machinery and are typically integral parts of the machinery. Gaskets are more static, even if they are form-in-place gaskets or joint sealants. Gaskets need to be fitted to the sizes and positions of the bolts that extend through them, but are easier to replace even if they are customised for a particular function or machine. Some mechanical seals are easily replaceable, but many of them need to be repaired or reinstalled if they break down, often together with the machine itself.

I need a gasket to be cut with very strict specifications. How can this be done?

You need look no further than Cotter Marketing’s computerised gasket cutting service. Using state-of-the-art technology, we cut gaskets from all materials, complying with required standards, and at very exacting tolerances where needed. We use templates that are pre-programmed, or we can create one from a sample. Our technology supports virtually any file format.

What’s the story with manway gaskets?

There is a known issue from the traditional usage of manway door gasket seals. The gasket tends to weaken at the point of start up, and then again during cooldown, resulting in leaks. Our partner, Chesterton, has come up with a solution for the manway door gaskets for these giant steam drums. We would be pleased to discuss these solutions with you if this issue relates to your plant.
