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.

Working Mechanism

  • The clamping force on these clamps rises and creates a spring function during the expansion or contraction, in response to thermal or mechanical influences such as temperature & vibration.
  • These thin-walled insert rings have an oval protrusion placed in the ear space (over the tube or hose end).
  • They are closed using hand installation pincers, thereby bridging and sealing the ear gap tightly. It also ensures a uniform compression force around the overall circumference of the clamp.
  • Burrs generated during forming and shearing are entirely removed in a barrel finishing process.
  • For a perfect seal, the ears must be closed correctly during the installation process, so the nominal diameter of the clamp must be chosen accordingly.

Features

  • Oetiker 151 Series medium-pressure clamps are thin wall insert rings with a double ear design for extra grip.
  • They are flexible enough to deliver a degree of elasticity owing to thermal expansion or vibration, thereby accommodating changes in the size of the components or parts being joined.

Compatible Accessories

  • Oetiker HO 3000 EL & HO 4000 EL: These electronically controlled pincers are designed for the brand's 151 Series clamps to provide uniform clamp closure.
  • Oetiker HMK 01 / S01: These manual ear clamp pincer tools have clamping jaws sitting straight on the pliers (HMK 01) or on the side of the pliers (HMK S01), for use in constrained spaces.

Standards and Approvals

  • DIN EN ISO 9227
  • IATF 16949:2016 and ISO 9001:2015
  • UNS S30403 (Unified Numbering System) and SAE 1008 (Society of Automotive Engineers)

Frequently Asked Questions

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.

How to measure the size of an ear clamp?

Simply analyse and measure the outer 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.

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.

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 tightens around the hose tightly and securely.

What other ear clamp variants does Raptor Supplies offer?

Besides 2 ear clamps, Raptor Supplies also offers 1 ear and stepless ear clamps.

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.

What types of clamps does Oetiker offer?

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

How to properly position a hose clamp?

Ear hose clamps come in a variety of shapes, styles and sizes. Most of them follow the same guidelines for proper placement on a hose / tube / pipe fitting. Once the hose is pressed securely onto the mating part, position the hose clamp toward the end of the hose, with approximately 1/4 inch space between the clamp and the end of the hose.
