Prevost Treated Steel Single Ear Clamp
The Permanent Solution for High-Pressure Hose Security
The Prevost Treated Steel Single Ear Clamp (also known as an Oetiker style clamp) is a high-performance fastening solution designed for permanent, tamper-proof hose connections. Unlike traditional worm-gear clamps that can be bulky and uneven, the single ear design provides a uniform, 360-degree radial seal that is ideal for compressed air, liquid, and gas lines.
Constructed from specially treated steel, these clamps offer the perfect balance of flexibility during installation and rigid strength once crimped, ensuring your fittings stay secure even under heavy vibration and thermal expansion.
Key Features
- 360-Degree Uniform Compression: Once the “ear” is crimped, the clamp applies equal pressure around the entire circumference of the hose. This eliminates the “flat spots” or gaps often found in screw-type clamps, preventing leaks in high-pressure applications.
- Treated Steel Durability: The steel is specially treated to provide enhanced resistance to corrosion and oxidation. This makes them suitable for use in humid workshop environments and industrial settings where exposure to moisture or oils is common.
- Tamper-Proof Security: Once installed, these clamps cannot be loosened or removed without being cut off. This provides a permanent, “set-it-and-forget-it” connection that prevents unauthorized adjustments or accidental loosening.
- Low-Profile Design: The compact, streamlined shape has no protruding screws or sharp tails. This prevents the clamp from snagging on clothing, machinery, or other hoses in tight engine bays or crowded manifold cabinets.
- Smooth Inner Band: The interior of the clamp is precision-finished to be smooth and burr-free. This protects the hose jacket from being pinched or cut during the crimping process, extending the life of your air lines.

Common Applications
- Pneumatic Assemblies: Securing hose barbs into air hoses for impact wrenches, grinders, and nail guns.
- Automotive Lines: Fastening fuel, vacuum, and coolant lines where space is limited and vibration is high.
- Fluid Transfer: Creating leak-proof seals on water and chemical lines in industrial cleaning systems.
- OEM Equipment: Used in the factory assembly of machinery to ensure air-tight connections that meet long-term reliability standards.
Installation Pro Tip
To achieve a perfect seal, select a clamp size where the hose diameter (with the fitting inserted) falls in the middle of the clamp’s range. Use a pair of side-closing or front-closing pincers to squeeze the “ear” until it is fully closed. The “ear” acts as a built-in spring, maintaining tension as the hose material expands and contracts with temperature changes.
