Stainless Steel Hose Clamp AWTools W4 20–32 mm, pack of 25

Stainless Steel Hose Clamp AWTools W4 20–32 mm, pack of 25 is a worm-gear hose clamp made of W4 stainless steel, sized to fit hose diameters from 20 to 32 mm and supplied as a set of 25 identical clamps. The clamp uses a threaded worm screw mechanism for adjustable tightening and is designed to provide reliable clamping force for hoses, pipes and duct connectors where corrosion resistance and mechanical durability are required. Its construction is intended for repeated installation and adjustment and for environments that demand improved resistance to moisture and chemicals compared with standard galvanized clamps.

Advantages

The W4 stainless construction offers enhanced corrosion resistance suitable for wet and humid conditions. The worm-gear design enables stepless, precise adjustment and a secure fit across the nominal 20–32 mm diameter range. Delivered in a pack of 25, the product supports multiple installations and replacements, reducing downtime and simplifying inventory management for professionals and DIY users alike.

Suitable for

• Plumbing hose and pipe connections
• HVAC duct and flexible hose fastening
• Automotive coolant and intake hoses
• General industrial and workshop hose securing

Key specifications

• Material: W4 stainless steel construction for shell and screw
• Type: Worm-gear (worm screw) hose clamp
• Clamping range: 20–32 mm nominal hose diameter
• Supply: Pack of 25 identical clamps
• Adjustment: Stepless tightening via threaded screw

How to use

Position the clamp over the hose end and the mating fitting so the band sits evenly around the connection. Turn the worm screw clockwise to tighten until the hose is held firmly against the fitting without crushing the hose material. For removal or readjustment, turn the screw counterclockwise. Use an appropriate screwdriver or nut driver that matches the screw head to avoid cam-out and to ensure controlled torque during installation.

Usage recommendations

Before installation, check that the hose and fitting are clean and free of sharp edges. Select clamps from the pack that match the hose outer diameter within the 20–32 mm range and avoid over-tightening to prevent hose deformation. For applications exposed to aggressive chemicals or marine conditions, inspect clamps periodically and replace if corrosion or mechanical degradation is observed.
