Prevost Solid Band Worm Drive Clamps (PBS9 Series)

Description

Prevost Solid Band Worm Drive Clamps (PBS9 Series)

Precision Clamping with a Slim Profile and Maximum Protection

The Prevost PBS9 Series is a professional-grade fastening solution designed for applications where space is limited but a high-performance seal is non-negotiable. Featuring a 1/3″ (9 mm) solid band, these clamps offer a narrower footprint than standard industrial clamps, making them the perfect choice for small-to-medium diameter hoses and tight engine or machine bays.

Like the larger PBS12 series, the PBS9 is engineered with a non-perforated band to protect your hoses from the “cheese-grater” effect caused by traditional slotted clamps.

Key Features

• 9 mm (1/3″) Slim Band: The reduced width allows for installation in narrow spaces where a standard 1/2″ clamp won’t fit, without sacrificing the structural integrity required for pressurized lines.
• Solid, Non-Perforated Interior: The band is smooth on the inside. This prevents hose extrusion—the process where the hose material is squeezed through the holes of a standard clamp—effectively eliminating the primary cause of leaks and hose failure.
• Rolled Safety Edges: The edges of the band are flared outward to prevent the clamp from cutting into the hose cover. This is especially important for thin-walled polyurethane, silicone, or soft rubber hoses.
• Vibration-Proof Locking: The precision-engineered worm gear housing ensures that once the clamp is tightened, it stays tightened. It resists loosening even when subjected to the constant vibration of pneumatic tools or industrial machinery.
• High-Quality Galvanized Steel: Built to resist corrosion in demanding shop environments, ensuring the screw remains turnable for future maintenance or adjustments.

Technical Specifications

The Performance Advantage

While standard “hardware store” clamps are designed for low-stakes home irrigation, the Prevost PBS9 is a true industrial component. The combination of a solid band and a high-torque housing provides a concentric, 360° seal that is vital for compressed air systems. By distributing the clamping force evenly around the hose, it ensures that the connection to your Prevost Hose Barbs is airtight and permanent.

Ideal Applications

• Pneumatic Tool Hoses: Perfect for 1/4″ and 3/8″ ID hoses where a compact, snag-free clamp is preferred.
• Fuel and Oil Lines: The narrow band is ideal for automotive fuel systems and oil return lines.
• Coolant and Vacuum Lines: Provides a reliable seal for small-diameter cooling systems and vacuum-assist circuits.
• Machine Plumbing: Ideal for internal air lines within CNC cabinets or automated assembly stations where space is at a premium.

Installation Tip

For the most secure fit, use a 7 mm nut driver. This prevents the slipping often associated with flat-head screwdrivers and allows you to reach the optimal torque setting to “seat” the hose into the barb without over-tightening.
