High-temperature environments, synthetic lubricants, acids, and aggressive chemicals. Silicone Rubber -55∘Cnegative 55 raised to the composed with power C +150∘Cpositive 150 raised to the composed with power C
Published by the Deutsches Institut für Normung (DIN), the DIN 3760 standard defines the dimensions, material specifications, tolerances, and marking requirements for rotary shaft lip seals. These seals are generally designed to be used in unpressurised equipment or systems with very low differential pressure.
: Often used in large machinery or heavy-duty applications, Type C adds an extra metal reinforcing cap to the standard Type B design for maximum rigidity.
Many universities and corporate engineering departments maintain subscriptions to standards databases. Check your organization’s library. Features a smooth outer elastomer or metal surface
For those interested in learning more about radial lip seals and DIN 3760, the following resources are available:
If you only require dimensions, tolerance charts, or material compatibility data rather than the legal testing framework, downloading a is an excellent alternative. Leading global seal manufacturers (such as Freudenberg Sealing Technologies/Simrit, SKF, Trelleborg, or Dichtomatik) publish exhaustive, free-to-download PDFs. These catalogs replicate the exact DIN 3760 geometric dimensions and offer comprehensive engineering application data. If you need help implementing these standards, tell me: What fluid or chemical will the seal be containing?

The standard provides tables covering shaft diameters from approximately 6 mm up to several hundred millimeters. Common ranges include:
: Retaining fluid/grease in unpressurized or low-pressure equipment.
