Hose Clamp Norma Opaska ślimakowa 12–22 mm, stainless steel adjustable worm-drive

Norma Opaska ślimakowa 12–22 mm is an adjustable worm-drive hose clamp designed to secure hoses and tubing with an inner diameter range of 12–22 mm. Made of stainless steel, the clamp provides consistent clamping force and resistance to corrosion, making it suitable for applications that require a reliable, adjustable seal. The slim profile and rolled edges reduce risk of hose damage while the worm-drive mechanism enables precise tightening and re-adjustment as needed.

Advantages

The stainless steel construction offers long-term corrosion resistance and durability in wet or corrosive environments. The worm-drive design allows for fine incremental tightening and secure retention under pressure or vibration. Its adjustable range of 12–22 mm covers a variety of small-diameter hoses and tubing, and the design minimizes sharp edges to protect hose material during installation and service.

Suitable for (tasks / use cases)

• Securing plumbing hoses and flexible pipe connections
• Automotive vacuum, coolant and small fluid line connections
• Industrial equipment with small-diameter tubing and pneumatic or fluid fittings
• Repair and maintenance tasks where a tight, adjustable seal is required

Key specifications

• Material: stainless steel
• Clamping mechanism: worm-drive (screw tightening)
• Adjustable clamp diameter range: suitable for hoses with inner diameters from 12 mm to 22 mm
• Profile: narrow band with rolled edges to reduce hose abrasion
• Torque control: allows incremental tightening for precise sealing

How to use

Position the clamp over the hose end, ensuring the hose is fully seated on the fitting. Engage the worm-drive screw and tighten slowly with a suitable screwdriver or nut driver until the clamp compresses the hose evenly against the fitting. Avoid over-tightening; tighten until a secure, leak-free connection is achieved and the hose outer surface is not visibly deformed. For rework or disassembly, loosen the screw to relieve pressure and remove the clamp.

Usage recommendations

Use the clamp within its specified diameter range (12–22 mm) and check compatibility of stainless steel with the fluids and environment in the application. For critical fluid systems, verify clamping torque and inspect periodically for corrosion, loosening, or hose wear, especially in applications with vibration or thermal cycling.
