Prevost Treated Steel Single Ear Clamp with Ring

The Professional Choice for High-Integrity, Leak-Free Connections

The Prevost Treated Steel Single Ear Clamp with Ring takes the reliability of a standard ear clamp and adds an internal “dimpled” ring for enhanced sealing performance. This internal ring is designed to bridge the gap under the “ear” of the clamp, providing a full 360-degree seal without any gaps or “steps.”¹

This specialized design ensures that even the most difficult-to-seal hoses—such as thin-walled tubing or hard, reinforced plastics—receive uniform radial pressure, making it the go-to choice for high-pressure pneumatic and hydraulic systems.

Key Features

• Internal Sealing Ring: The integrated ring sits inside the clamp band, providing a smooth, continuous inner surface. This eliminates the small gap that can occur under the ear of standard clamps, ensuring a perfect, leak-proof seal around the entire hose circumference.
• Treated Steel Construction: Manufactured from high-tensile steel that has been specially treated for superior corrosion resistance. This treatment ensures the clamp maintains its structural integrity even in damp, oily, or harsh industrial environments.
• Vibration-Resistant Permanent Seal: Once crimped, the “ear” acts as a spring-loaded tensioning element. It maintains a constant grip on the hose, automatically compensating for the material’s expansion and contraction due to temperature shifts or pressure surges.
• Snag-Free Low Profile: The streamlined design lacks the bulky screws and sharp edges of traditional worm-gear clamps. This makes it ideal for use in tight spaces where hoses might rub against one another or against machinery.
• Safety and Security: These clamps are tamper-proof and cannot be loosened once installed. This ensures that critical air or fluid lines remain connected and prevents accidental disconnection in high-traffic work areas.

Technical Specifications

Common Applications

• Industrial Pneumatics: Securing air tool hoses to quick-connect plugs and hose barbs for a professional, factory-finished look.
• High-Vibration Machinery: Ideal for engine compartments or vibrating factory equipment where traditional screw clamps might vibrate loose over time.
• Thin-Walled Tubing: The internal ring provides the delicate, even pressure required to seal soft or thin-walled tubing without pinching or tearing the material.
• Fluid Distribution: Used in beverage lines, water treatment, and chemical transfer where a 100 percent gap-free seal is required to prevent drips.

Installation Guide

For a successful installation, slide the clamp over the hose before inserting the fitting. Ensure the internal ring is seated flat against the hose. Using a pair of ear clamp pincers (either front or side-closing), squeeze the ear firmly until the clamp is tight. The ring will ensure that the pressure is distributed evenly, even directly under the crimped ear.
