Product catalog summary
Overview: The document is a technical catalog from Oetiker, detailing specifications and ordering information for Stepless® Ear Clamps, specifically Product Groups 123 and 193. These clamps are designed for uniform compression and surface pressure, ensuring secure and reliable connections.
Materials:
  • PG 123: Made from high strength steel (material no. 1.0934), zinc-plated with optional galfan coating.
  • PG 193: Made from stainless steel (material no. 1.4301/UNS S30400), offering the highest corrosion resistance (≥ 1000 hours).
Specifications:
  • Standard Series: Sizes range from 25.0 to 120.5 mm, with varying band widths and thicknesses.
  • Heavy Duty Series: Sizes range from 24.5 to 120.5 mm, with thicker bands for increased durability.
Design Features:
  • 360° Stepless® design for uniform compression.
  • Closed interlock for high radial loads.
  • Teardrop embossment for higher radial loads with compressible materials.
  • Clamp ear for compensating component tolerances.
  • Burr-free strip edges to reduce damage risk.
  • Security hook to prevent unintended opening during transport.
Assembly Recommendations:
  • Use tools recommended by Oetiker for closing clamps.
  • Ensure uniform closing force to maintain tension loading and tolerance compensation.
  • Process monitoring is advised when using Oetiker ELC electronically controlled pneumatic pincers.
Installation Data:
  • Detailed closing force requirements are provided for different material dimensions and clamp sizes.
  • Maximum closing forces depend on material hardness and are specified for thermoplastics and other materials.
Order Information:
  • Comprehensive list of item numbers, reference numbers, and specifications for ordering clamps in various sizes and materials.
Important Notes:
  • Figures are intended as a guide and may vary based on part tolerances.
  • Functional tests are recommended to ensure optimal clamp selection.
Contact Information: The catalog includes contact details for Oetiker offices in various countries, including Switzerland, Austria, Canada, China, Czech Republic, France, Germany, Hong Kong, Hungary, India, Japan, Netherlands, Spain, South Korea, United Kingdom, and USA.
Additional Notes: The data provided in the catalog is based on extensive experience and is intended for reference purposes, not as design specifications.

Note: the above sketch shows the appearance of a closed “ear” (s’); it does not necessarily indicate an effective closed assembly. The following applies as a guideline: To determine the correct clamp diameter, push the hose onto the attaching material, (e.g. the nipple), and then measure the outer diameter of the hose. The value of the outer diameter must be slightly above the average value of the diameter range of the clamp to be selected. The clamp is only sufficiently closed (minimal diameter reduction) if the original ear width is reduced by at least 40% (for an ear with a 10.7 mm width)...
