Oetiker - 1" Stainless Steel Crimp Clamp


SKU: 331-SS
  • Clamp ear: fast and simple assembly, visible deformation provides evidence of proper closure
  • Dimple: increases clamping force
  • Burr-free strip edges: reduced risk of damage to parts being clamped

  • Dimple: increases clamping force
  • Burr-free strip edges: reduced risk of damage to parts being clamped

Using tools designed or endorsed by Oetiker, the clamp is closed by drawing together the lower radii of the €œear€. The maximum diameter reduction is proportional to the open €œear€ width.
The theoretical maximum reduction in diameter is given by the formula:

Max. diameter reduction = Ear width (s)
                                                   Ï€

To ensure perfect sealing, clamp ears must be correctly closed during assembly.

Clamp diameter
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. Select a clamp whose average value of the diameter range is slightly greater than the hose€™s outer diameter.

Mechanical interlock
The mechanical interlock is a mechanical connection which keeps the clamp securely closed. By using a mechanical interlock instead of spot-welding, corrosion around the closure elements is reduced.


Assembly recommendations
The clamp ear should be closed with a constant tool jaw force, this practice is referred to as €œforce priority closure€. This assembly method ensures that a uniform and repeatable stress is applied to the application with a constant tensile force on the mechanical interlock.
Employing this methodology when closing 105 & 155 series clamps will compensate for any component tolerance variations, and ensure that the clamp applies a constant radial force to the application. Fluctuations in component tolerances are absorbed by variations in the €œear€ gap (the space between the lower radii after assembly).

Closing force
It is important to realize that there is in a very close relationship between the desired compression of the material being clamped and the closing force selected. The table below gives maximum closing forces in relation to the size of the part being clamped. 

Important
Single tool stroke closure only, do not apply secondary crimping force.
