Different elastomers for o rings and various applications

An elastomer is a primary raw material used for most o rings. They are typically manufactured as gum rubber or manufactured synthetically, and surprisingly today, there are approximately over 32 different synthetic rubbers now available.  Elastomer compounds will...

Spiral wound gasket thickness – what’s best?

It is often recommended that using a thinner gasket type/material will result in better sealing performance.  Why?  Because thinner gaskets tend to require much less gasket stress to provide applications with the perfect seal, they also have an excellent response to...

Choosing the correct oil seal application

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.  Of course, all rubber materials and seals will provide a range...

Nitrile rubber, NBR, and Buna-N – how well do you know your o ring materials?

A widely used elastomer, Nitrile, Buna-N, or NBR rubber, are all oil and fuel resistant and provide a great level of strength, making them a popular material for seals across various industries.  Suitable for a range of applications, this versatile rubber material,...

Optimum squeezing force for an o ring

It is true that the more squeeze you place on an o ring, the tighter the seal it will provide. In essence, the more squeeze (compression) you apply, the greater the force between the o ring and its mating hardware.  And ensuring you have the perfect seal is all...

O Ring Squeeze

The squeeze and shrinkage on an o ring are vital to understanding as these factors stand in the way of your application either experiencing a perfect seal or your application suffering from leaks.  You can measure the shrinkage of an o ring during...

Keeping your o rings bonded

EMI o rings. Those seal ring gaskets are made of silicone compounds, combining environmental sealing with electromagnetic interference protection.  Consisting of metal or metal-coated particles, silicone o rings are filled with silver, silver aluminium, or nickel...

The importance of mechanical seals when reducing water consumption in mining

Environmental considerations are at the top of most industry's agendas in the 21st century as companies evaluate and improve operations, processes, and systems.  Conserving water in mining is one such area that is now being investigated further with the rotation of...

How choosing the correct gasket reduces risks

Health and Safety across any industry are vital, especially so in industrial facilities and settings.  Why?  Because harmful leaks and emissions must be avoided at all costs to avoid serious accidents or injury to your teams and property.  That’s why having the right...

How to tighten your bolts perfectly

How to tighten your bolts and which tools you should use to achieve the perfect seal is not as seamless and straightforward as we would like. Various factors come into play in these situations, such as bolt grade, size, and even application type.  Tightening torques...

Manufacturing of High-Quality Gaskets

Manufacturing of High-Quality GasketsA large number of engineering and machinery applications use gaskets. This mechanical seal is employed whenever gaps between two or more surfaces are joined together. This process is also required to prevent leakage and withstand the extremes of compression when working.

Depending on the requirements of the application, the seals and gaskets used can be manufactured from a variety of materials. Just in a standard washing machine alone, a cork gasket (to suppress noise) and a watertight gasket, are both essential to the finished product.

Seals and gaskets need to be high-quality, and the process must start with the manufacturer. They need to use the latest technology in making gaskets from the best constituents and to the highest specifications.

Materials Used for Manufacturing

Gaskets can be made from any sheet materials such as paper, rubber, silicone, metals, cork, Neoprene®, PTFE, plastic, fibreglass and asbestos. Technology is continuously discovering new ways to manufacture gaskets from better and more innovative materials.

It is not just the correct sizing that is necessary for perfect gasket mating; the material choice is a vital component as well. Gaskets need to be tough yet flexible enough to allow compression.

Gaskets mate two surfaces that will erode or grind against each other by providing a buffer. Because this can mask any surface irregularities, the gasket must also fill them and ensure that no gas or fluids leak, which often occurs under high compression.

A reputable gasket manufacturer will utilise only the highest quality materials to produce the most precisely made products. The gasket market is global. The best way to source a gasket or seal is to build up a relationship with a supplier who understands how critical these well-made products are to an application.

When a gasket manufactured by the punching process is not suitable, one can be precision made using a cutting process. Depending on the material, the specialised gasket will be cut using lasers or high-pressure water jet. For an even more bespoke gasket service, expert technicians will hand cut one according to the application needs. This is a technique often used for vintage cars.

Gasket suppliers, such as Specialist Sealing Products, stock gaskets and seals that are traditionally manufactured in high volumes. They have a wide selection that incorporates the many different materials, sizes and types that is sure to suit diverse engineering projects.

The Use of Gaskets

A gasket’s primary function is to be reliable in its job to join and seal. This is proof that only the best materials and manufacturing processes produce acceptably high-quality gaskets. Gasket suppliers like Specialist Sealing Products understand this and use only manufacturers that they have carefully vetted.

Many new manufacturers have entered the global gasket market. This is good in that it keeps prices realistic and supply plentiful, but the drawback can be that not every country sets such high standards for overseeing the manufacturing process. Rely on your reputable gasket and seal supplier to know the best products for you.
