The Evolution of Gasket Solutions

When we talk about gaskets and the history of a gasket, we must start at the very beginning.  What is a gasket?  Ultimately, a gasket is a manufactured seal that is used to fill the gap/space between two or more surfaces.  Gaskets are typically manufactured by cutting...

How to preserve your gasket

Gaskets and seals don’t last forever. However, they are designed, or they should be, last for a considerable period.  In this sense, it is vital to look at ways to preserve your gaskets in order to avoid any application downtime.  Downtime that involves additional...

Important Design Features of Rubber Sealings

When it comes to designing the perfect rubber sealing, there are a few design features to bear in mind to help achieve the optimum solution.  In this post, we explore these rubber sealing features further and provide information on the benefits and best uses for these...

Optimal Squeeze for an O Ring to be effective

A doughnut-shaped seal that is primarily used to stop liquids and air from escaping or getting into specific spaces is the function and role of an O Ring.  Also known as a mechanical gasket, O rings are designed to fit between a groove and a compression during the...

High-temperatures and O Rings, what you need to know

Fluctuations in temperature and indeed heat is a significant factor across many applications that make use of o rings.  However, what is well known is how destructive heat can be when it comes to compound deterioration.  You are making choosing the ideal o ring...

How to restore your damaged rubber seals

Under the right circumstances and having the right tools to hand, you can restore rubber gasket seals and have them working as good as new in no time.  Rubber gasket seals provide a seal between two separate mechanisms, providing airtight seals to keep liquids and...

The importance of backup rings to O rings

Backup rings are ultimately used to help stop o ring migration, and they achieve this in both static and dynamic fluid power applications as the pressure cycles occur, preventing the extrusion of an o ring in the gap.  Ultimately a backup ring is a rigid ring that...

Gasket manufacturing process explained

Specialist Sealing Products have been providing high-quality gaskets to customers throughout the UK for many years. We pride ourselves in the range of gaskets we have available, suitable for a variety of applications across a range of industries.  Rubber gaskets are...

Designing seals for the food industry

There’s a number of factors to take into consideration when designing seals for the food industry. That’s because seals used within this sector need to work exceptionally hard in all food processing environments where hygiene and health and safety are of the utmost...

Storing your gaskets!

A strange headline for a gasket article, we know.  However, it’s an important area and one, which in this sector is often overlooked.  When we think about most products or items in and around our homes and business, we will recognise that most come with manufacturing...

VEE PACKINGS/CHEVRON SETS

Vee Packings, also referred to as Chevron Sets are universal multi-part seals that are highly regarded for their long working life and ability to operate under adverse mechanical conditions in rod and piston locations. 

This robust packing set, specially designed for up and down movement of plunges and axels in pumps and valves, comprises of three different elements, the gland ring/female adaptor, the header/male adaptor and multiple intermediate ‘V’ shaped rings. Activation is by lip sealing as the intermediate ‘V’ rings are tapered to give an initial interference when confined in the seal housing. The resulting radial force ensures good sealing. 

Vee Packings are used for both low and high-pressure applications with single or double acting cylinders with each single intermediate ‘V’ ring reacting to pressure to create an effective seal along the shaft. 

Vee packings are designed and available in a wide range of different material configurations and combinations in order to give best and most effective sealing results based and dependent upon different media and chemicals, temperaturespressures and surface speeds in any given specific application.
