Product catalog summary
Overview
Oetiker's Stepless® Ear Clamps from Product Groups 123 and 193 are advanced clamping solutions designed for uniform compression and surface pressure. They are available in various sizes and materials, offering high strength and corrosion resistance.

Materials and Corrosion Resistance
PG 123 clamps are made from high-strength steel with zinc-plated or galfan coating, providing corrosion resistance of ≥ 96 hours for zinc-plated and ≥ 144 hours for galvanized. PG 193 clamps are made from stainless steel with corrosion resistance of ≥ 1000 hours.

Specifications
The clamps are available in standard and heavy-duty series with varying size ranges, widths, and thicknesses. The standard series includes sizes from 25.0 to 120.5 mm, while the heavy-duty series ranges from 24.5 to 120.5 mm. Ear widths are available in 10.7 mm and 13.0 mm.

Design Features
The Stepless® design ensures uniform compression, with features like closed interlock, teardrop embossment, and dimple to increase clamping force and accommodate component tolerances. Burr-free strip edges reduce damage risk, and a security hook prevents unintended opening.

Assembly Recommendations
Clamps should be closed with a uniform closing force to maintain constant tension without overloading components. The use of Oetiker ELC electronically controlled pneumatic pincers is recommended for process monitoring and documentation.

Installation Data
Installation tools and maximum closing forces vary by material and size. For PG 123, closing forces range from 2400 N to 5000 N, while PG 193 ranges from 2600 N to 8000 N. Specific tools are recommended for each configuration.

Order Information
Clamps are available in various size ranges and configurations, with specific item numbers and reference numbers provided for ordering. The catalog includes detailed size ranges and specifications for each clamp type.

Important Notes
The data provided is based on extensive experience and is intended for reference, not as design specifications. Functional tests are recommended to ensure optimal clamp selection.

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)...
