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. View our selection below and do contact us with any questions you may have about our products or the solutions you require.

Gaskets are designed to prevent leakage. Industrial gaskets are commonly used as follows:
The nature of your specific operations determines the gasket sealing solution you require.
A partnership with Cotter brings you a combination of excellent products, advice, expertise, and training:
The first gasket was produced two centuries ago! The timing makes sense because the Industrial Revolution was in acceleration mode during this period. The materials that were used to produce gaskets went through a number of iterations. Starting off as solid seals made out of iron filings, sulphur, and water, the gasket materials quickly progressed to treated rope and tar, and were ubiquitously applied in the shipping industry of the time. The need for gaskets and seals in shipping is, of course, an obvious one—one which really defines what gaskets and seals are all about. And Cotter Marketing has been there. This is a result of the company’s early beginnings in the shipping industry, albeit not as far back as 1820!
Different types of gaskets are suited to different industries, and these types of gaskets come in a number of designs.
Our partner, Chesterton, supplies many of our top sealing products. Below are a couple of the company’s popular semi-metallic gaskets that are suitable fits for a variety of sealing processes.
Are you dealing with some tricky sealing situations? The Steel Trap / Graphite Gasket will likely solve your issues. The convoluted concentric design of the steel literally traps the graphite as the flange tightens. The resulting compression forms a tight seal that eliminates the risk of leaks and pressure blow-outs. By reducing vulnerability due to weak compression or too much pressure, this gasket brings you the best of both worlds: leak-proofing and pressure resistance. Its material and design make it less susceptible to temperature and pressure cycling, and when “Live Loaded”, it is similar to a weld.
The cost-effective sealing solution of the spiral wound gasket is quite versatile because it can be configured in a number of different designs and shapes. It consists of metal windings combined with graphite or PTFE material, as well as supporting rings on the inner and outer sides of the gasket.
Gaskets produced from sheet material tend to be more economical. All Chesterton sheet material gaskets that are distributed by Cotter Marketing, are produced from materials of the highest quality.
The Chesterton 455 is a general-purpose Aramid fibre gasket with strong chemical tolerance. However, it should not be used with chlorinated hydrocarbons, or with aromatic and ester ketones. It comes in a sheet composed of a combination of synthetic fibres and a nitrile binder.
The very versatile Chesterton 359 is a general purpose gasket, with a high resistance to chemicals, and it is unlikely to decompose at high temperatures. This is attributed to its strong thermal stability. The gasket material consists of a graphite sheet reinforced with stainless steel and is easy to handle.
The strength of the nylon-reinforced sheet of the Chesterton 122NN is the reason behind its superior performance.
Form-in-place (FIP) gaskets are more unconventional that their standard fitted cousins. They eliminate the need to figure out exact fittings, and are definitely time-savers. Useful for mechanical assemblies, as well as intricate surfaces.
The easy-to-apply Chesterton 860 Mouldable Polymer Gasket is also easy to remove. It forms a very thin gasket, retains its elasticity, and is resistant to vibration.
Example applications: Housings, fittings, turbine casings, vacuum systems
The Chesterton 185 form-in-place joint sealant provides a very easy and fast method of sealing joints. It is resistant to chemicals and is highly stable, even in high-pressure situations. If you’re looking for cost-effectiveness and longevity, the 185 is the solution for you.
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.
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.
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.
A gasket is not a standalone device. Its inner and outer workings are very much dependent on the substance that it has been built to control. The flow of the fluids or other media through the system impact the strengths as well as the weaknesses of the gasket. The media both gives the gasket its life, and depends on it for its containment.
This relationship between a gasket and the flow of media, can be compared to the relationship of Cotter Marketing with both its suppliers and its customers. Our company, together with the quality manufacturers that we work with, enjoys the cohesiveness of our relationship with you, your plant, and your industry.
Cotter Marketing is very solution oriented, and this supports our holistic approach towards assisting our customers. We provide technology and products, not only in sealing, packing, and gaskets, but we also specialise in non-destructive testing, metal and concrete coating, industrial lubricants, and more.
We look forward to providing you with solutions and support. We are happy to respond to any enquiries you may have about our company, our services, and our gaskets.
