Prevost Treated Steel Double Ear Clamp

The Professional Choice for Permanent, Tamper-Proof Hose Connections

The Prevost Double Ear Clamp (also known as an “Oetiker” style clamp) is a rugged, high-security fastening solution designed for permanent hose assemblies. Unlike standard worm-gear clamps that can loosen over time or snag on clothing, these dual-ear clamps provide a uniform, high-tension squeeze around the entire circumference of the hose.

Engineered for the demands of industrial pneumatic systems, these clamps are the ideal choice for creating custom air leads, whip hoses, and permanent shop-floor installations.

Key Features

• 360° Uniform Compression: The “double ear” design allows the clamp to deform symmetrically when crimped. This provides a constant, even pressure around the hose, ensuring a 100% leak-proof seal even under high-vibration conditions.
• Zinc-Plated Treated Steel: Manufactured from high-tensile steel and treated with a protective zinc coating to resist corrosion, oxidation, and chemicals found in shop environments.
• Tamper-Proof Security: Once crimped, these clamps cannot be loosened or removed without being cut. This prevents accidental adjustments and ensures the integrity of your pressurized lines.
• Low-Profile, Snag-Free Finish: With no protruding screws or sharp tails, these clamps are significantly safer for operators. They won’t catch on skin, clothing, or other hoses when being dragged across a workspace.
• Vibration Resistant: The mechanical tension of the crimped “ear” acts as a spring, absorbing pulses from the air compressor and maintaining a tight seal where traditional screw clamps might back off.

Installation Tips for a Perfect Seal

1. Selection: Choose a clamp size where the hose’s outer diameter (OD) is roughly in the middle of the clamp’s range.
2. Crimping: Use a pair of pneumatic or manual ear-clamp pincers. For the best results, squeeze both ears simultaneously (if using a specialized tool) or one after the other to ensure even deformation.
3. Check: Once crimped, the “ear” should have a small gap at the top, indicating that it is maintaining constant spring tension on the hose.

Why Choose Treated Steel Over Stainless?

While stainless steel is excellent for marine environments, Prevost Treated Steel clamps offer a higher “clamping force-to-cost” ratio for indoor industrial applications. They provide superior mechanical strength and a “bite” that is perfect for heavy-duty rubber or reinforced PVC hoses.
