What is a gasket?

A gasket is a mechanical seal, which fills the space between two mating surfaces, generally to prevent leakage by filling in the irregularities between “less than perfect” mating surfaces.The choice of its material depends on the specific application and the conditions it will be subjected to. Some factors that are considered when selecting a gasket material include the temperature, pressure, and chemical resistance required.

Purpose of Gasket:

1. To confine gas, oil, water, vacuum or exhaust.

2. Seal out foreign objects such as dirt or water.

3. Must withstand heat, cold, pressure, erosion, corrosion, moisture & oil.

Classifications: Gaskets are classified into two types

1. Hard gaskets -Made of steel, copper or composite of metal & fibre.

2. Soft gaskets:-Made of cork paper or rubber.

The thickness of the gasket is not same. it will vary as required and where it will be fitted.

How to cut a gasket?

Cutting a gasket can be a simple process if you have the right tools and materials. Here are the general steps to cut a gasket: 

Determine the gasket material: The first step is to determine the material you want to use for your gasket. Common materials include rubber, cork, and paper. 

Measure the dimensions: Measure the dimensions of the gasket you need to cut. Use a ruler or tape measure to determine the length, width, and thickness of the gasket. 

Mark the material: Use a pencil or marker to mark the outline of the gasket onto the material. Or make a sample paper drawing. You can do this by placing the part that needs a gasket onto the material and tracing around it. 

Cut the material: Use a sharp cutting tool such as a razor blade, scissors, or a gasket cutter to cut along the marked outline. It’s important to use a sharp blade to ensure a clean and accurate cut. 

Clean up the edges: Once you have cut the gasket, use sandpaper or a file to smooth any rough edges. This will ensure a tight seal and prevent leaks. 

Install the gasket: Once you have cut and cleaned the gasket, you can install it onto the part that requires it. Make sure to align it properly and use the appropriate sealant if needed.  Remember, always wear protective gear such as gloves and eye protection when cutting gaskets to prevent injury.


What is Devcon putty?

Devcon Putty is the original metal-filled epoxy putty for economical maintenance and repair work. It is recommended for repairing cracks and breaks in equipment, machinery or castings. It consists of resin and hardener, which are mixed in a particular ratio and applied.

Why are Devcon products used onboard Ship?

It is a repair kit which can be used anywhere on Ship, where permanent repairs are not possible for time being. Like there is a leak in the seawater line & welding is not possible right now, then for time being Devcon putty will carry out temporary repairs for the safe operation of the Vessel. Welding of the pipe will be carried out at the next convenient opportunity.

Devcon putty applying process:

Clean the surface using, Devcon surface cleaner. Then 2.5 parts of resin with 1 part hardener. Then apply putty and push onto the surface to be repaired. After the metal is repaired it may be sanded, filed or machined as needed

Various kinds of Devcon Putty Used On Ship:

Plastic steel putty – Most commonly used on Ships. It is a steel-filled epoxy putty which hardens in an hour.

2. Devcon Plastic Steel 5-minute putty — As the name suggests, this putty hardens much faster than normal Plastic steel putty. It is a steel-filled epoxy putty for emergency repairs in less than an hour.


3. Devcon Underwater repair putty.

4. Devcon Stainless steel putty.

5. Devcon Aluminium putty.

6. Devcon Bronze putty.

7. Devcon Titanium putty.
