OET10100016 - Oetiker 1113 Double Ear Clamp for 1/4 Inch ID Hose

Precision Sealing with Oetiker 2-Ear Technology

The Oetiker 2-Ear Zinc-Plated Hose Clamp (SKU: OET1113) represents a standard of excellence in permanent hose sealing solutions. Engineered for critical industrial and automotive applications, this clamp features a specific clamping range of 0.425 inches to 0.512 inches (approximately 10.8mm to 13.0mm), making it suitable for hoses with a nominal 1/4-inch inner diameter and standard wall thickness. The defining feature of this component is its 2-ear configuration. Unlike standard worm-gear clamps, the 2-ear design provides an extended range of clamping force and, crucially, adds a degree of elasticity to the connection. This spring-like action allows the clamp to breathe with the application, accommodating changes in hose size due to thermal expansion, contraction, or vibration without losing seal integrity.

Manufactured from high-quality zinc-plated steel, this clamp offers robust corrosion resistance suitable for most indoor and general industrial environments. The manufacturing process pays close attention to the band edges; they are carefully deburred to prevent the steel from cutting into the soft hose material during crimping or operation. This is particularly vital for silicone or soft rubber hoses often found in pneumatic and fluid transfer systems. The installation process creates a permanent, tamper-proof seal that cannot be easily loosened by vibration or accidental contact, ensuring system reliability. The visible deformation of the ear upon crimping serves as an immediate visual quality control check, confirming that the clamp has been properly installed.

This clamp is an essential component for MRO professionals requiring reliable, low-profile connections. Its compact one-piece design eliminates bulky housings that can snag on surrounding equipment, making it ideal for tight spaces within machinery or complex piping assemblies. Whether used for air lines, fluid lines, or low-pressure hydraulic systems, the Oetiker 2-Ear clamp delivers consistent, leak-free performance.
