Hose Clamp Topex 37D505, stainless steel W2, adjustable diameter 20–32 mm

Topex 37D505 is a worm-drive hose clamp made from W2 stainless steel, offering an adjustable diameter range of 20–32 mm. It secures hose-to-pipe and hose-to-fitting connections by applying uniform pressure through a threaded worm gear that engages a slotted band. The clamp is suitable for tasks that require a compact, adjustable fastener resistant to light corrosion and mechanical wear.

Advantages

The W2 stainless steel construction provides improved resistance to corrosion compared with plain steel, making the clamp suitable for intermittent exposure to moisture. The worm-drive mechanism allows for precise diameter adjustment and repeatable clamping torque, while the slotted band design distributes pressure evenly around the hose to reduce the risk of leaks. Its compact profile and simple screw adjustment make installation and removal quick using common hand tools.

Suitable for

• Securing rubber and silicone hoses to barbed fittings
• Plumbing connections with small-diameter pipes and tubing
• Automotive vacuum lines and coolant hoses (non-high-pressure systems)
• General repair, maintenance and DIY projects requiring adjustable clamping

Key specifications

• Material: W2 stainless steel band and housing
• Clamping range: 20–32 mm adjustable diameter
• Drive type: worm-drive screw
• Band type: slotted metal band for uniform pressure distribution
• Typical tool: flathead or cross-head screwdriver for adjustment
• Profile: low/standard profile suitable for confined spaces

How to use

Place the clamp over the hose end and slide the hose onto the fitting or pipe until it seats fully. Position the slotted band so it overlies the fitting barb or the thickest part of the hose, then tighten the worm-drive screw clockwise until the clamp exerts firm, even pressure without deforming the hose. To remove or adjust, turn the screw counterclockwise until the band loosens and slides off. Use a compatible screwdriver and avoid excessive torque to prevent damage to the clamp or hose.

Usage recommendations

For long-term outdoor or marine use select a higher-grade stainless steel clamp; for applications involving high pressure or critical safety requirements use clamps specified for that service. Inspect clamps periodically for signs of corrosion, thread wear or loss of tension and retighten after initial service if necessary.
