Prevost Solid Band Worm Drive Clamps (PBS12 Series)

Description

Prevost Solid Band Worm Drive Clamps (PBS12 Series)

The Industrial Standard for High-Torque, Hose-Safe Fastening

The Prevost PBS12 Series represents a significant upgrade over standard perforated hose clamps. Engineered with a 1/2″ (12.7 mm) solid band, these worm drive clamps are designed for heavy-duty industrial applications where a permanent, leak-proof seal is required.

Unlike common hardware-store clamps that “cheese-grate” your hoses through perforated slots, the PBS12 features a smooth internal surface and rolled edges, ensuring that your high-pressure air, water, or oil lines remain undamaged even under extreme tension.

Key Features

• Non-Perforated (Solid) Band: The band is stamped rather than perforated. This eliminates the “slots” that allow hose material to extrude and shear under pressure, significantly extending the life of your hose assemblies.
• Rolled Edges for Hose Protection: The edges of the 1/2″ band are specially flared outward. This design ensures the clamp will not cut into the hose cover, which is critical for vibration-heavy environments or when using softer rubber and silicone hoses.
• High-Torque Housing: The worm gear housing is mechanically interlocked (not welded) to the band. This construction allows for higher tightening torques without the housing tilting or failing, providing a more uniform 360° seal.
• Superior Corrosion Resistance: Constructed from high-quality galvanized steel (or stainless steel depending on specific model suffix), the PBS12 is built to withstand shop oils, moisture, and chemical exposure without seizing.
• Versatile Hex-Head Screw: The 7mm hex-head screw features a deep slot, allowing for tightening with a socket wrench, nut driver, or screwdriver for maximum installation flexibility.

Technical Specifications

Why the PBS12 is the Professional Choice

In compressed air systems, a loose or “leaking” clamp is a constant drain on your compressor and your wallet. Standard clamps often loosen over time due to thermal expansion or vibration. The Prevost PBS12 provides a wider footprint (1/2″) than mini-clamps, distributing the clamping force over a larger area. This makes it the ideal companion for Prevost Hose Barb fittings, ensuring that the hose is locked into the barbs with enough force to handle the standard 174 PSI of industrial air systems.

Ideal Applications

• Main Air Lines: Securing 1/2″ and larger rubber or hybrid air hoses to couplers and manifolds.
• Industrial Cooling: Managing water lines for machinery and welding equipment where leaks can be catastrophic.
• Automotive Repair: Heavy-duty coolant hoses and air intake boots where high vibration is present.
• Agriculture & Construction: Field repairs on pressurized fluid lines that require rugged, reliable hardware.

Sizing Guide

The PBS12 series is available in a wide range of diameters. To select the correct size, always measure the Outside Diameter (OD) of your hose after it has been pushed onto the barb or fitting.
