Sealing & Gasket Technology

Sealing & Gasket Technology prevents leakage of liquids and gases and protects equipment against dirt or water. The category includes O-rings, gaskets, flange gaskets, shaft seals, hydraulic and pneumatic seals, mechanical seals and compression packing.

A seal closes the space between components in a static joint or during linear and rotary movement. The sealing principle depends on the function: a flange gasket seals a joint, a linear seal works with a rod or piston, and a mechanical seal retains the medium where a shaft passes through rotating equipment.

Seals are used across industrial sectors. Named applications include pumps, mixers, rotating shafts, hydraulic and pneumatic equipment, flange joints, machine building, chemical installations and power plants. ERIKS also supports custom production through SealXpress and advice on the appropriate sealing function.

First determine whether sealing is static, linear or rotary. Then specify the medium, equipment and sealing location, such as a flange, rod, piston or shaft. Select the product type and decide whether a standard item, machined seal or fully customised product is required. Treat compression packing separately from mechanical seals.

Key attributes are sealing function, static or dynamic movement, medium, equipment, sealing location, product type and standard or custom manufacture.

Frequently asked questions

A product belongs in this category when its primary function is to seal liquid, gas, dirt or water. Select the underlying group according to a static joint, linear movement, rotating shaft or flange connection.

Hydraulic and pneumatic seals operate with linear movement in cylinders and comparable equipment. This function includes sealing around rods and pistons and the associated guiding and dirt-exclusion functions.

Mechanical seals retain liquid or gaseous media in pumps and mixers where the shaft passes through the equipment. Shaft seals form a separate group for rotating shafts, including oil seals and types that keep dirt or water out.

SealXpress supports the production of custom seals. Select a custom product where a standard item does not match the sealing function or required dimensions; define the application, movement and sealing location for the request.
