OET10100022 - Oetiker 1517 Double Ear Clamp, 14mm-17mm Range, Zinc Plated

Reliable Industrial Sealing with Oetiker 2-Ear Clamps

The Oetiker 2-Ear Zinc-Plated Hose Clamp (Model 1517) is an industry-standard solution for creating permanent, leak-proof connections in fluid and gas lines. Engineered for critical applications where vibration, thermal cycling, and pressure fluctuations are common, this clamp offers superior performance over traditional worm-gear clamps. The defining feature of this model is its "2-Ear" design. Unlike single-ear variants, the double-ear configuration provides an extended clamping range (0.551 inches to 0.669 inches) and increased elasticity. This elasticity acts as a built-in spring, accommodating changes in hose size due to thermal expansion or contraction, ensuring the seal remains tight over time.

Manufactured from high-quality zinc-plated steel, this clamp is designed to resist corrosion in standard industrial environments. The material selection balances strength and ductility, allowing the ears to be crimped securely without fracturing. A critical detail in Oetiker's manufacturing process is the treatment of the band edges. The edges are carefully deburred to prevent them from cutting into the hose material during installation or operation, protecting the integrity of the underlying tubing. This is particularly important for softer hose materials often used in pneumatic and hydraulic low-pressure systems.

Installation of the Oetiker 1517 is fast and efficient, requiring only a standard pair of pincers to close the ears. Once crimped, the clamp provides a tamper-proof seal; it cannot be loosened or adjusted, which prevents accidental disconnection or unauthorized modification. The visible deformation of the ears serves as a clear quality control indicator, allowing inspectors to visually verify that the clamp has been properly closed. With a band width of 0.315 inches, it provides ample surface area to distribute clamping force evenly, minimizing the risk of leak paths.

This clamp is ideal for OEM applications, maintenance repair operations (MRO), and assembly lines requiring consistent, repeatable sealing results. Whether securing coolant lines, air hoses, or fuel lines, the Oetiker 2-Ear clamp delivers a robust connection you can trust.
