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).
- 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
- Industry and mechanical engineering
- Vehicle manufacturing and commercial vehicles
- Domestic installations and plumbing
- Wherever reliable and tight hose connections are required
- ABA Nova C7 worm drive hose clamp in the selected variant (material & clamping range)
