Gasket manufacturing

Gasket manufacturing is a process that determines the reliability of machines, installations, and equipment in many industries. In industrial practice, leakage is one of the most common causes of failures and at the same time one of the most costly. Even a slight deformation of rubber, a microcrack in a flange gasket, or wear of an O-ring can lead to loss of medium, pressure drop, or destabilization of device operation. In such situations, standard catalog gaskets are often insufficient — they may not fit dimensionally, may not be resistant to the given medium, or may not meet temperature requirements. Therefore, custom gasket manufacturing has become a key service for industry, workshops, and technical services.

At Power Rubber, gasket manufacturing is treated as a process requiring material knowledge, precise measurements, and appropriate technology selection. It is a deliberate design of a component that must operate under specific conditions and ensure full tightness, not just quick cutting of a shape from rubber.

Why is gasket manufacturing so important?

In many production facilities, a gasket is a small element, but its role is crucial. It is responsible for maintaining the medium in circulation, pressure stability, operational safety, and protection against leaks. When a gasket stops functioning properly, the consequences can be serious: from production line shutdown, through equipment damage, to risks for employees.

Gasket manufacturing is particularly important when:

• the part is not available on the market

• dimensions are non-standard

• operating conditions have changed

• delivery time for the original part is too long

• it is necessary to match the material to a specific medium

In such cases, custom gasket manufacturing allows obtaining a component perfectly matched to a specific application, not just the “closest possible”.

What does the gasket manufacturing process look like?

The gasket manufacturing process consists of several stages, each of which affects the durability and effectiveness of the final component.

Analysis of operating conditions

This is a key stage, as operating conditions determine the material selection. At Power Rubber, the process always starts with collecting information about:

• medium (water, oil, fuel, steam, chemicals, air, food)

• minimum and maximum temperature

• static and dynamic pressure

• type of movement (static or dynamic)

• exposure to UV, ozone, and weather conditions

• special requirements (e.g., food certifications)

Without this data, material selection would be random, which could lead to rapid gasket wear.

Measurements and documentation

A gasket can be recreated based on:

• an old element (even damaged)

• a technical drawing

• measurements taken directly from the device

The most important parameters are:

• inner and outer diameter

• thickness

• spacing and diameter of holes (for flange gaskets)

• profile shape (for frame and door gaskets)

• dimensional tolerances

In practice, it often turns out that the old gasket is deformed — therefore it is important to consider its original dimensions, not only those after years of operation.

Material selection

Material selection is the foundation of gasket durability. Each elastomer has different properties and resistance.

SBR
Used in general applications — water, air, standard conditions.

NBR (nitrile rubber)
Best choice for oils, fuels, and lubricants.

EPDM
Resistant to hot water, steam, UV, ozone, and weather conditions.

FKM / Viton
Elastomer with the highest chemical and thermal resistance.

Silicone
Flexible over a very wide temperature range.

Micro rubber and foams
Used in doors, covers, housings, insulation.

Selection of manufacturing technology

Depending on shape and quantity, different methods are used:

• cutting from sheets

• CNC cutting

• die cutting

• profile bonding

• molding or vulcanization

Each method is selected according to the specific project.

Quality control

The finished gasket must:

• meet dimensional tolerances

• be made of the correct material

• maintain appropriate hardness

• ensure tightness under operating conditions

Common mistakes when ordering gaskets

• providing only dimensions without medium information

• sending a worn gasket without considering original dimensions

• lack of information about type of movement

• too general description of the medium

• selecting material “by eye”

Avoiding these mistakes significantly extends gasket lifespan.
