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.
Oetiker 153 Series single ear clamps are used for fastening flexible hoses or tubing to a connection where a permanent joint is required. They are suitable for fuel line systems, air conveying pipes, airbags, water cooling / heating systems and low pressure hydraulic systems.
How do you use Oetiker 153 Series single ear clamps?
Why use Oetiker 153 Series single ear clamps?
Measure the outer diameter of the hose after the hose is attached to the attaching component (for example, the nipple) and then determine the correct clamp diameter. In order to select the correct clamp, the value of the outer diameter must be slightly above the average value of the diameter range.
Raptor Supplies offers an extensive catalogue comprising Oetiker ear, screw, stepless ear, stepless screw & worm gear clamps. We also sell accessories such as straps, clamps, rings, connectors and assembly & disassembly tools from Oetiker.
Customers can use tools such as a side or bowl nose cutter to remove Oetiker clamps from hoses. It is not recommended to use rotating cutters as they can cause damage to the hose while cutting the clamp.
