Butterfly Clamp DeLOCK 400 SS 8 - 12 mm 5 pieces black

The DeLOCK Butterfly Clamp 400 SS is a set of five stainless steel hose clamps designed for hose diameters from 8 to 12 mm. Each clamp is 9 mm wide and finished in black, combining a corrosion-resistant stainless steel band with plastic components to allow tool-free installation on pipe ends. The clamps hold hoses securely under pressure and are suitable for a range of DIY, home and garden, automotive and plumbing tasks.

Advantages

Made from stainless steel with plastic parts for ease of handling, these butterfly hose clamps offer corrosion resistance and a compact 9 mm width. The tool-free butterfly tightening mechanism enables quick installation and removal while ensuring a firm grip that prevents hose slippage under pressure. Supplied as a set of five, they provide consistent performance across multiple fittings.

Recommendations

Ensure the hose diameter falls within the 8–12 mm range for a secure fit. Inspect clamps periodically for damage or corrosion, and replace if the plastic head shows wear or the stainless band is deformed. Avoid overtightening on soft hoses to prevent damage to the hose wall.
