Product catalog summary
Overview: The document outlines the technical specifications and guidelines for Oetiker's Stepless® Ear Clamps, specifically Product Groups 117 and 167. These clamps are designed for applications requiring a secure seal or load, with material dimensions selected based on the necessary stress.
Material Specifications:
  • PG 117: Made from galvanized or zinc-plated steel.
  • PG 167: Made from stainless steel (Material no. 1.4301/UNS S30400), offering the highest corrosion resistance (≥ 1000 hours).
Size and Dimensions:
  • PG 117: Sizes range from 11.9 mm to 24.9 mm with varying widths and thicknesses.
  • PG 167: Sizes range from 6.5 mm to 120.5 mm, available in standard and heavy-duty series.
Design Features:
  • Narrow band design for concentrated clamping force.
  • Stepless design ensures uniform compression.
  • Clamp ear compensates for component tolerances.
  • Dimple design increases clamping force and compensates for thermal expansion.
  • Burr-free edges reduce damage risk.
Assembly and Installation:
  • Clamps are closed using tools designed by Oetiker, ensuring a consistent closing force.
  • Block closure should be avoided to ensure effective force transfer.
  • Mechanical interlock allows for radial installation before closure.
  • Force priority closure method is recommended for uniform stress application.
Installation Tools and Force:
  • Various manual, pneumatic, and electronically controlled tools are recommended based on clamp size and material.
  • Closing force varies by material and size, with specific tools recommended for each.
Important Considerations:
  • Ear height should not be altered during installation.
  • Single tool stroke closure is recommended.
  • Functional tests are advised to ensure optimal clamp selection.
Order Information: Detailed item numbers and size ranges are provided for both PG 117 and PG 167 clamps, with specific dimensions and ear widths listed.
Specifications: The document provides details on Oetiker clamps, specifically the Stepless® Ear Clamps PG 117 & 167, designed for PEX pipe connections. The clamps are available in various sizes with band widths of 10 mm and thicknesses of 0.8 mm and 1.0 mm. They are available in diameter ranges from 24.5 mm to 120.5 mm, with increments of 0.5 mm upon request.
Standards and Compliance: The clamps comply with ASTM F877/F2098 standards and are suitable for PEX applications. They are listed under the NSF product listing cNSFus-PW and are designed to ensure tamper detection and high radial loads.
Warnings and Recommendations:
  • Use only plastic fittings in high chloride water conditions.
  • Avoid installation in contact with concrete.
  • Use only ASTM F1807 or F2159 insert fittings with Oetiker clamps.
Assembly Recommendations: Proper assembly requires the clamps to be completely closed, using ratchet pincers that only open when the clamp is fully secured. Specific installation tools and force requirements are provided for different PEX sizes.
Order Information: The document lists item numbers, reference numbers, ear widths, and PEX size ranges for ordering purposes.
Contact Information: The document includes contact details for Oetiker offices worldwide, including locations in Switzerland, Austria, Canada, China, Czech Republic, France, Germany, Hong Kong, Hungary, India, Japan, Netherlands, Spain, South Korea, United Kingdom, and USA.

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. A clamp can only be considered adequately closed when the ear width (s) has been reduced by at least 40%, and the correct closing force was used for assembly....
