Screw (Worm Gear) Hose Clamp BRADAS BSW2 50–70/9 Stainless Steel, 50–70 mm

BRADAS BSW2 50–70/9 is a stainless steel screw (worm gear) hose clamp with an adjustable diameter range of 50–70 mm. The clamp features a 9 mm wide band and a worm-drive screw mechanism that converts rotational movement into uniform clamping force. Manufactured to ISO9001-aligned quality standards, this clamp is intended to secure hoses, pipes and ducts while minimising the risk of damage to the hose material and offering resistance to corrosion.

Advantages

The worm-drive design delivers consistent, controllable tension across the band for reliable sealing. Stainless steel construction improves durability and corrosion resistance in humid or chemically active environments. The 9 mm band width balances contact area and flexibility to reduce point loading on hose walls, lowering the chance of cuts or deformation. Precision machining and standardised dimensions ensure repeatable performance and compatibility with a wide range of hose types.

Suitable for

• Plumbing connections and water lines
• Automotive hose assemblies (coolant, air, vacuum lines)
• HVAC duct and ventilation hose fastening
• General repair, workshop and industrial hose clamping tasks

Key specifications

• Material: stainless steel band and housing for enhanced corrosion resistance
• Clamping range: adjustable from 50 mm to 70 mm
• Band width: 9 mm for balanced contact and strength
• Drive type: screw (worm gear) mechanism providing uniform clamping torque
• Construction: perforated band with captive screw assembly for secure operation

How to use

Position the clamp around the hose and the mating fitting so the band sits evenly over the connection. Ensure the hose is fully seated on the barb or spigot before tightening. Use a screwdriver or appropriate driver on the worm screw and rotate clockwise to tighten until the desired compression and seal are achieved; avoid over-tightening which could deform the hose. To loosen, rotate the screw counterclockwise until the band can be removed. Inspect the clamped joint after initial use and periodically during service life to confirm continued tension and integrity.

Usage recommendations

Choose the clamp size that allows the band to sit within the middle of its adjustable range on the hose and avoid extreme tightening. For corrosive environments, verify compatibility of stainless steel with the specific media. Replace clamps that show visible deformation, stripped threads, or loss of clamping force.
