Are your gaskets completely compliant?

In industries where gaskets are not just important but essential, there are numerous challenges to be faced and considerations to take on board.  This is especially true when it comes to making sure this “essential” element is also compliant.  With the implementation...

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...

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...

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...

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...

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...

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...

Why Colour Matters When Choosing Gaskets?

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 the centre gasket ring; the colour stripes placed at intervals on the outside designate what non-metallic winding filler materials were used 

These not only help to identify and choose products, but they also set an industry standard so that the correct gasket is selected for an application. 

A limited colour selection can no longer satisfy consumers who seek more diversity to match the multitudes of applications. The colours range from standard grey all the way to the most vibrant hues. Thus, it is possible to match the colour of the seals and gaskets to doors and windows where they will hide in plain sight. 

Any queries about the use of gaskets, gasket colours or seal colours, can be expertly answered by the technicians at Specialist Sealing Products. The training and long-term association with seals and gaskets guarantees the staff can swiftly understand any application requirements and solutions 

How a Spiral Wound Gasket Colours Will Look 

The standard used for the fabrication of spiral wound gaskets is called ASME B-16.20. It requires an inner ring to be placed on all PTFE manufactured gaskets in all available classes. 

These colours denote the materials used, the temperatures they have been manufactured to withstand, and will have an abbreviation of the material stamped on the ring. 

When looking at the gasket from a transverse section so that it looks like the rings around the planet Saturn and starting from the innermost centre (otter) ring, there is a stamp with numbers and letters that indicate the materials used to make the gasket. 

Looking at the outer ring, there will be a gasket manufacturer’s stamp with their registered name. This will help anyone looking for a particular brand. 

There are four other stamps on the outer ring that help identify the gasket properties and specs.  

  • Stamps with plain numbers and a letter indicate the material when it is something other than carbon steel. 
  • Stamp that looks the same as the one listed above but with a forward stroke / followed by letters indicates the gasket filler material. 
  • Stamps also have the standard manufacturing rating such as ASME B-16.20. 
  • A stamp with measurements indicates the nominated pipe size and pressure rating.

Gasket Identification Using Colour Guide 

For even better ways of being able to tell the materials used in a gasket, there are colours to guide the buyer. There is sure to be a colour coded chart that will assist in choice, as even seasoned engineers sometimes struggle to remember the properties of the many different colours and what they denote.  

Some gaskets have no colourThis is not deliberate; the defining properties of the gasket will be able to be understood from reading the stamps as demonstrated in the previous section. Staff at Specialist Sealing Products will be on hand to assist any colour or stamp queries.
