Oetiker® 155 Series Ear Clamps, Mechanical Interlock, 5-9mm Band Width




Oetiker® 155 Series Ear Clamps with Mechanical Interlock, 5-9mm Band Width

Oetiker Logo

These single ear clamps provide a mechanical interlock, rather than a standard spot weld.

This mechanical interlock furthers enhances durability and corrosion resistance.

  • Burr-free edges reduce damage to hoses being clamped
  • Narrow width concentrates clamping force
  • Suitable for Tubing or Hose
  • Composed of Stainless Steel

Selection: Measure the outside diameter (O.D.) of the hose to be clamped. Select a clamp with an average size range that is close to the hose’s O.D. An optimal clamp size will allow the hose’s O.D. to fall in the middle of the clamp’s size range.

Clamping Procedure: After assembling the hose, use an Oetiker® ear clamping tool to compress the clamp’s first ear, followed by clamping the second.  The clamp’s ears should be reduced in size by at least 40% to provide enough clamping force. If sized correctly, the clamp’s ears should not close completely during compression.

Note: All Clamps sold in Bag Quantities of 100
