Hose Clamp Norma Opaska ślimakowa 110–130 mm, stainless steel, model 735770

Norma Opaska ślimakowa hose clamp model 735770 is a stainless steel worm-drive clamp designed for secure fastening of hoses, pipes and ducting with diameters in the 110–130 mm range. The clamp uses a threaded worm gear that engages a perforated band to provide adjustable and repeatable clamping force. Constructed from corrosion-resistant stainless steel, it is intended for environments where durability and resistance to rust are required.

Advantages

The stainless steel construction offers corrosion resistance and dimensional stability over time, while the worm-drive mechanism enables precise adjustment and secure tightening with common hand tools such as a screwdriver or socket. Its adjustable diameter range makes it versatile for different hose and pipe sizes within the specified span, and the continuous band design distributes clamping pressure evenly to reduce leakage risk and material damage.

Suitable for

• Automotive hose connections (air intake, coolant lines, exhaust systems where applicable)
• Industrial and manufacturing hose lines and ducting
• Plumbing and HVAC connections requiring corrosion-resistant clamps
• Temporary or permanent repairs and assembly tasks involving flexible tubing

Key specifications

• Material: stainless steel (band and housing)
• Type: worm-drive (screw) hose clamp
• Adjustable diameter range: 110–130 mm
• Band style: continuous perforated band for even pressure distribution
• Drive interface: standard slotted or hex head suitable for screwdriver or socket

How to use

Position the clamp over the hose or duct so the band lies evenly around the circumference and the hose end seats properly on its mating fitting or pipe. Engage the screw drive using a screwdriver or compatible socket and turn clockwise to tighten until the clamp provides a firm, leak-free seal without deforming the hose. To remove or loosen, turn the screw counterclockwise. Inspect the clamp and hose after installation to ensure proper seating and no pinching or over-compression of the hose material.

Usage recommendations

For best results, select the clamp size that places the operating diameter near the middle of the 110–130 mm range. Avoid over-tightening to prevent damage to hose walls; apply torque gradually and check the seal under operating pressure. Use stainless steel clamps in corrosive or outdoor environments and replace clamps that show significant wear, galling, or thread damage.
