Prevost Mini Worm Clamps

Precision Compression for Small-Diameter Lines

The Prevost Mini Worm Clamp (often referred to as a Nut and Bolt or Fuel Line clamp) is a specialized fastening solution designed for small-diameter hoses where standard, bulky gear clamps fail to provide a uniform seal. Unlike traditional worm-gear clamps that can “oval” or pinch thin-walled tubing, the Prevost Mini Clamp provides a consistent, 360° concentric squeeze.

These are the professional choice for securing polyurethane, PVC, and thin-walled rubber hoses to barbs, ensuring a leak-free connection that stands up to industrial vibrations.

Key Features

• Non-Perforated Band: The interior of the band is smooth and free of the “slots” found in standard gear clamps. This prevents the hose material from extruding through the band under pressure, which is the leading cause of hose failure and leaks in small lines.
• Rolled Edge Design: The edges of the band are slightly flared or rolled outward. This ensures that the clamp never “bites” or cuts into the hose cover, even when tightened to maximum torque.
• Nut and Bolt Mechanism: Instead of a long, perforated track, these clamps use a high-strength nut and bolt system. This provides a much higher clamping force relative to their size and prevents the “stripping” common in cheap hardware store clamps.
• Zinc-Plated Steel Construction: Treated for superior corrosion resistance, these clamps are built to survive in oily, humid, and demanding shop environments without rusting or seizing.
• Compact Profile: The small footprint makes these ideal for tight spaces, such as inside machine cabinets, under vehicle dashboards, or on compact pneumatic manifolds.

Technical Specifications

The “Leak-Proof” Advantage

Small air lines (under 1/2″ OD) are notoriously difficult to seal with standard clamps because the “flat spot” under the gear housing creates a leak path. The Prevost Mini Worm Clamp eliminates this issue with its circular geometry, ensuring that the hose is pressed firmly against every barb of the fitting. This is especially critical for automated machinery where even a microscopic “hissing” leak can cause pressure drops and sensor errors.

Ideal Applications

• Pneumatic Control Lines: Securing 6mm, 8mm, or 10mm tubing to barb fittings in control panels.
• Fuel & Oil Lines: Perfect for small engine repair and automotive fuel return lines.
• Coolant Overflows: Managing small-diameter cooling hoses in industrial or automotive settings.
• Lab & Medical Air: Providing a clean, professional finish on clear vinyl or silicone tubing.

Installation Tip

For the best results, use a nut driver or socket rather than a screwdriver. This allows you to apply precise torque without slipping, ensuring the bolt is tight enough to “seat” the hose into the barb without over-compressing the material.
