Hose clamp Norma Opaska ślimakowa 70–90 mm, stainless steel, adjustable worm-gear

Norma Opaska ślimakowa 70–90 mm is an adjustable worm-gear hose clamp designed to fasten hoses and pipes with diameters from 70 to 90 mm. Made from stainless steel, the clamp resists corrosion and provides consistent compression around flexible and semi-rigid hoses. The worm-gear mechanism enables precise adjustment and secure locking, making it suitable for repeated use in maintenance and installation tasks across automotive, plumbing, HVAC and light industrial settings.

Advantages

The stainless steel construction ensures improved corrosion resistance compared with standard plated clamps, extending service life in damp or chemically active environments. The worm-gear design delivers fine adjustment and reliable clamping force, while the adjustable range of 70–90 mm covers common hose diameters used in ventilation ducts, coolant lines and drainage systems. Its reusable nature allows easy removal and reinstallation during repairs or component replacements.

Suitable for

• Securing automotive coolant and air intake hoses with 70–90 mm diameter
• Washing machine, dishwasher and appliance drainage hoses
• HVAC duct connectors and flexible ventilation conduits
• Plumbing connections on non-pressurized or low-pressure lines
• Light industrial tubing and temporary hose assemblies

Key specifications

• Material: stainless steel for housing and band
• Adjustment range: 70–90 mm diameter
• Clamping mechanism: adjustable worm-gear screw
• Typical applications: hoses and pipes with circular cross-section
• Reusability: designed for multiple assembly/disassembly cycles

How to use

Place the clamp around the hose end and position it over the connection point or barb. Turn the worm-gear screw clockwise using a screwdriver or nut driver until the band provides firm but not excessive compression; avoid overtightening that could damage the hose. To remove or reposition, turn the screw counterclockwise until the band loosens and can be slid off. Inspect the clamped joint after initial run-in and re-torque if needed to maintain a leak-free seal.

Usage recommendations

For best results, select clamp placement over a smooth section of hose near the fitting shoulder, and use the appropriate torque to prevent material deformation. In corrosive or marine environments, periodically inspect the clamp and surrounding components for signs of wear or corrosion and replace as necessary.
