Housing: New compact housing – one-piece pressed, mechanically locked, no weld spots
Traceability: Code on each clamp
Application: Hose connections in industry, vehicle manufacturing, and domestic installations
Item Description▼
The ABA Nova C7 worm drive hose clamp is the new generation of proven ABA clamps, offering reliable, tight connections for maximum safety. The newly designed compact housing ensures even clamping force and secure band guiding. The short housing saddle provides optimal contact pressure on the hose.
ABA Nova clamps have been extensively tested and exceed the requirements of standard DIN 3017. They also comply with standard SS 2298 and combine low idle tightening torque with high clamping force. Available in material versions W1 (standard with Aluzinc band), W4 (stainless steel) and W5 (acid-resistant stainless steel).
Product Advantages
New compact housing – stronger and more evenly distributed clamping force
Special screw design – lower idle tightening torque
Mechanically locked – no weld spots, prevents contact corrosion
Housing base lock – secures against band slipping due to impacts
New band marking – indicates material & size of the clamp
Traceability code on each clamp
Hose-friendly – rounded edges and housing bottom reduce risk of leakage
Clamping force reserve – high breaking strength combined with high clamping force
Areas of Application
Industry and mechanical engineering
Vehicle manufacturing and commercial vehicles
Domestic installations and plumbing
Wherever reliable and tight hose connections are required
