lekdichtingen

Lekdichtingen are components used to prevent leaks at joints and interfaces in machinery, piping and vessels. The term covers a broad family of devices such as gaskets, packing, seals and related elements like O-rings, lip seals and mechanical seals. They can function as static seals between fixed surfaces or as dynamic seals that accommodate movement, rotation or vibration, maintaining leak-tight operation under defined pressures, temperatures and chemical environments.

Common materials and types include elastomers (NBR, EPDM, FKM/Viton, silicone), PTFE, graphite and metals. Static seals often employ flat or ring-shaped gaskets, while dynamic seals include shaft seals, lip seals and mechanical seals. Hygienic variants exist for food and pharmaceutical applications. The choice of lekdichting depends on chemical compatibility, temperature range, pressure, surface finish and installation constraints, as well as the expected service life and ease of maintenance.

Applications span automotive engines, pumps, valves, piping systems, heat exchangers and pressure vessels across industries such as energy, chemical processing, water treatment and food and beverage. Proper selection and installation are essential: ensure compatible material and geometry, prepare mating surfaces, apply correct compression or torque, and avoid damage during assembly. Regular inspection and leak testing help detect wear or degradation; replacement is advised when signs of wear, chemical attack or loss of seal performance occur.
