155 Series Stainless 1 Ear Clamps With Mechanical Interlock
Oetiker ear clamps are designed to provide dependable and semi-permanent clamping of hoses in the petrochemical, hydraulic & automotive industries. These ear clamps are ideal for use in cross linked polyethene (PEX) tubing & water supply piping systems. They feature visible deformation to provide indication of proper closure and a dimple to deliver maximum clamping force. They are available in variants having single or double ears. Users should choose a single ear clamp if they want to achieve uniform compression around the hose / tube, and a double ear variant for extended clamping range, when dealing with materials that are vulnerable to thermal expansion or contraction.
Oetiker 155 Series ear clamps are equipped with a single ear for quick installation & clamping. They are made of stainless steel, chromium & nickel for structural strength, corrosion resistance & durability. These 155 Series ear clamps are integrated with a mechanical interlock for securely closing the clamps and preventing corrosion associated with spot welding closure of the clamps. They have specially formed, burr free strip edges with 7 mm band width & 0.6 mm thickness to reduce damage to the hoses being clamped. Raptor Supplies offers these Oetiker stainless steel clamps in clamping width range of 8.9 to 99.5 inches. We also supply these ear clamps in galvanised steel construction for mild corrosion resistance & ductility.
Oetiker 155 Series stainless steel single ear clamps are suitable for clamping hoses for leak proof operation in agricultural, heating, automobile & cooling applications. These clamps prevent the disconnection of hoses on applying high clamping pressure, without damaging the hoses.
Oetiker 155 Series stainless steel ear clamps are placed over a hose and closed using a mechanical interlock. These clamps are crimped across their ear width by drawing together their lower radius using a constant force pincer. The decrease in open ear width results in reduction of clamp diameter and hence, leads to tightening of the applied clamp around a hose.
Frequently Asked Questions
Are other variants of Oetiker 155 Series ear clamps available on Raptor Supplies?
Raptor Supplies offers these ear clamps in variants having two clamp ears for maximum clamping force while adjusting to thermal expansion / contraction. We also offer these ear clamps in galvanised steel variants (105 Series clamps) for mild corrosion resistance & ductility.
What is the significance of burr free strip edges?
Oetiker 155 Series ear clamps have burr free strip edges for complete protection of clamped parts against scarring or mechanical damage due to high clamping pressure.
How can users select the right ear clamp for their needs?
- Application: Single ear clamps are used in thermally stable environments where the hose & clamp diameter remain constant. Double ear clamps are ideal for environments where the hose diameter can fluctuate (increase or decrease) due to temperature change.
- Construction: Ear clamps are available in variants having galvanised or stainless steel construction. Zinc plated steel ear clamps have slightly lesser resistance to corrosion than stainless steel ear clamps.
- Outside diameter: Select a clamp that has the hose diameter in the middle of the clamping range.
What types of clamps does Oetikar offer?
Oetiker offers a wide range of hose clamps like screw, ear, spring, wire, worm gear and plastic clamps.
How to properly position a hose clamp?
Hose clamps come in diverse shapes, styles & sizes. However, the majority of them follow the same process for proper fitting on a hose and tube / pipe fitting. Once the hose is pressed securely onto the mating part, the hose clamp is positioned toward the end of the hose, with approximately 1/4 inch space between the clamp and the end of the hose.
How can users remove an Oetiker clamp?
Customers can use tools such as a side or bowl nose cutter to remove clamps from hoses. It is not recommended to use rotating cutters as they can cause damage to the hose while cutting the clamp.
Can Oetiker clamps be reused after removal?
Selected models of Oetiker clamps, like low profile, universal & screw clamps, can be reused after removing them from hoses that do not require clamping.
