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.

154 Series 1 Ear Clamps With Insert

Hose clamps with an insert (like Oetiker 154 Series stainless steel one ear clamps) are ideal for clamping hoses where a more secure hold is required, as compared to conventional clamps. These single ear clamps feature a thin walled insert ring to ensure near uniform compression around the circumference of the clamp and are suitable for applications involving soft or hard rubbers & plastics. The dimple or indentation on the ear of these clamps increases the clamping force to provide a tighter hold.
They are incorporated with a mechanical interlock for easily closing the clamps, and offer greater corrosion resistance than spot welded clamps. Additionally, these clamps are made from stainless steel, so they can resist corrosion and scaling. They are useful for applications such as food processing and commercial fishing, which involve exposure to corrosive elements, especially salt water. Models without inserts (Oetiker 153 Series single ear clamps) are also available on Raptor Supplies.

153 Series 1 Ear Clamps, Stainless Steel

What are Oetiker ear clamps?
Oetiker ear clamps are designed to connect a tube to a pipe or fitting (like a hose barb connection) without an adhesive. These non greased clamps are ideal for applications where leakage is a concern. By maintaining very low geometry, the closed ear increases clamping force and creates a spring effect when the hose material expands or contracts in response to thermal or mechanical influences such as temperature & vibration. These ear clamps are a great alternative to plastic securing clamps and zip ties.
Oetiker 153 Series single ear clamps are made of stainless steel and are spot welded instead of using a mechanical interlock, to offer superior structural stability and corrosion resistance. Once the bands have been pinched around the hose, the clamps are placed over the end of the connecting hose, tightening the band around the hose & creating a secure fit. To ensure that you have a proper fit, make sure that the ear clamp size is only slightly larger than the hose size. There should be a difference of 0.4 mm between the inside diameter of the clip and the overall diameter of the tube & fitting. It is recommended to use a single ear clamp when space is limited, and a double ear clamp when there is enough space. These Oetiker stainless steel ear clamps are integrated with a mechanical interlock for keeping the clamps securely closed and preventing corrosion due to spot welding closure of the clamps. They have uniquely formed, burr free strip edges for reducing the risk of damage to hoses or other parts being clamped. Raptor Supplies offers these Oetiker ear clamps in sizes ranging from 2.9 to 17.5 inches.

151 Series Stainless Steel 2 Ear Clamps

Oetiker 151 Series ear clamps are medium-pressure clamps that feature a double-ear design for extra grip and providing constant pressure around the hose, thereby making them suitable for handling thermal and vibrational expansion or contraction. They are made from anti-corrosive stainless steel to offer increased clamping range as compared to standard ear clamps, as well as provide additional durability. Oetiker stainless steel ear clamps feature deburred edges to prevent damage to the hose and have the capacity to deliver a degree of elasticity owing to thermal expansion or vibration, to accommodate changes in the size of the components or parts being joined. The visible deformation of these ear clamps provides evidence of their proper closure and the one piece configuration ensures a positive & tamper resistant seal. These steel ear clamps are available in sizes ranging from 3.1 mm to 46 mm and band thicknesses up to 0.394 inches. Raptor Supplies is a trusted supplier of Oetiker clamps.

Frequently Asked Questions

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 do we tighten a clamp?

To tighten a clamp, squeeze the clamp with one hand so that the end opposite the driver slides into the sleeve holding. Then, turn the driver clockwise with a wrench or screwdriver so that the threads present on the driver engage the slots on the clamp. Continue turning the driver until the clamp securely tightens around the hose.

How to size an ear clamp?

Simply analyse and measure the outside diameter (OD) of the hose installed on fitting. Then, choose a hose clamp in such a way that the outer diameter of the hose is approximately in the middle of the clamping range of the clamp.

Are Oetiker clamps reusable?

Raptor Supplies also offers Oetiker stepless low profile clamps that are reusable in nature. They can be opened and installed multiple times and can be mounted both radially & axially. Oetiker's low profile, universal, screw & profile clamps are also reusable in nature.

How do you remove an Oetiker clamp?

Tools like a rotating or bowl nose cutter or side cutter can be used for removing Oetiker clamps. However, rotating cutters are not recommended as they might tamper or damage the hose while cutting the clamp.

What is the difference between 1 and 2-Ear clamps?

Oetiker 2 ear clamps have a larger clamping range as compared to 1 ear clamps. These 2 ear clamps offer high clamping force and create a spring effect during contraction and extension of the hose.

What types of clamps does Oetiker offer?

Oetiker offers a wide range of clamps including screw, ear, spring, wire, worm gear and plastic clamps.

Which types of ear clamps offer enhanced resistance against corrosion?

Clamps made of stainless steel are corrosion-resistant. So, if you're looking forward to using these clamps in outdoor settings, you should opt for the ones made of stainless steel.

What is the difference between ear clamps and worm gear clamps?

Worm gear clamps use a screw to tighten which may not evenly distribute pressure, whereas ear clamps have a crimping mechanism that provides a more uniform and secure seal.
