Everything you need to know about Manway Gaskets

When it comes to manway gaskets, we want to keep things simple, introducing them as the small sealing ring found in hatches/openings that are constructed for large tanks. Openings which give people access to the inside of the aforementioned tanks and vessels. The...

How Do You Recognise a Quality Gasket?

A gasket is a very simple item that is reasonably inexpensive. Considering how gaskets work, you may be facing a costly bill should a gasket fail. Choosing a quality gasket from Specialist Sealing Products helps to create a seal that will last until well after the...

5 Common Gasket Failures

Common Failure Causes  A blown head gasket in a vehicle is something that needs to be fixed promptly. If left untouched, you run the risk of seriously damaging your engine. Knowing what causes gasket failure or gasket problems is the key to gasket failure prevention,...

O-ring Size Guidelines

The performance of an O-ring seal depends largely on two factors— the right material and the right size. However, determining the right size O-ring is usually the hardest part when it comes to choosing the right O-ring for an application.   Unfortunately, selecting...

Tips for Proper O-Ring Installation

  An O-ring is a crucial component of a fluid system, and how it is installed can make or break that system. To ensure the success of an application, O-ring requires not only careful material selection and design but also proper installation procedures. A small...

Why Colour Matters When Choosing Gaskets?

Gasket manufacturers have turned to colour coding gaskets to make the selection and categorisation of the product more accessible.   It is possible to identify the winding and filler materials that were used for fabrication by the colouring of the outer top side of...

Materials that can be Used in Producing Gaskets

Seals and gaskets are meticulously manufactured to be able to withstand the exacting conditions under which they function. Not only does a gasket seal two distinct parts and allow the containment of extreme temperature fluids, steams and gases, but it must meld the...

Choosing the Perfect Gasket for Your Needs

The perfect gasket choice and fit is an essential component of engines, appliances, and industrial machinery projects. They are a fundamental part when engineering anything from power tools to oil drills. A high-quality manufacturer of gaskets and seals will use only...

Manufacturing of High-Quality Gaskets

A 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...

O Ring Materials Selection

This is a quick overview of the various O-Ring materials that are available for applications and found at select UK O-Ring suppliers. When it comes to Specialist Sealing Products, it is a good idea to be clued into every option that is on the market. The materials can...

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.
