German Thorsman rubber gaskets specialize in complete dust-proof and waterproof sealing for cables, conduits, and pipes, serving as experts in cable and pipe sealing for mechanical equipment. The ingress protection rating of mechanical equipment reflects its resistance to moisture and dust. This is particularly critical for outdoor applications exposed to harsh environments with high humidity or dust and sand, where effective sealing and waterproofing are essential to ensure safe operation and equipment longevity.

In 1957, a man named Oswald Thorsman (Oswald Thorsman) had an idea for better mounting of lamps and similar items. He molded the first sample of what is now known as the rubber gasket in his kitchen oven. This innovation led to the founding of the Thorsman company, and soon after, junction boxes, cable trunking, and other essentials for electricians followed.

Thorsman gaskets are used in automobiles, aircraft, ships, electrical and hydraulic equipment, enclosed equipment, and luminaires to prevent dust and water from entering machinery. The gaskets are approved by Lloyds Shipping Register (Lloyds Shipping Register) and Det Norske Veritas (Det Norske Veritas) for marine and offshore applications, and their watertightness is recognized by the national accreditation bodies of Sweden, Norway, Denmark, and Finland. Thorsman gaskets are available in two materials: ethylene propylene (EPDM) rubber and chloroprene (CR) rubber. Protection rating IP67, compliant with IEC. Both materials are weather-resistant and heat-resistant, suitable for indoor and outdoor use.

Advantages of German Thorsman rubber gaskets

1) Quick installation – sealing without tightening the grommet

2) Allows vibration of cables, conduits, and pipes without compromising the seal

3) The sealing membrane is pierced only when the cable passes through – acts as a blind plug and is ready for installation

4) Approved for installation on ships

5) Very wide sealing range for each size.

6) High protection rating – IP67

Thorsman gaskets protect against dust ingestion (complete protection against contact and dust penetration) and temporary water immersion (protection against dipping). In addition, the waterproof and dustproof performance of the gaskets must consider factors such as temperature and vibration resistance in other harsh environments. Not all systems with high protection ratings are entirely problem-free. High levels of waterproofing and dustproofing usually require completely sealed installations, which often cause heat dissipation issues. System errors caused by overheating may occur, necessitating additional cooling devices.
