Norma W3 Worm Drive Stainless Steel Hose Clamp 20-32mm 210231

The Norma W3 Worm Drive Hose Clamp delivers professional-grade performance with innovative design features that ensure secure, reliable connections for hoses ranging from 20mm to 32mm in diameter. Constructed from durable stainless steel (430), this 12mm-wide clamp features an improved asymmetric housing that distributes forces evenly during assembly and tightening, preventing housing tilt and ensuring consistent clamping pressure across the entire hose circumference.

Engineered for ease of installation, the W3 includes screw support for safe guidance of the band end during assembly, while the material and clamping range are conveniently stamped on the band to prevent sizing errors. The short housing saddle provides even contact pressure for improved efficiency, and the smooth or stamped band interior offers optimal hose protection, preventing damage to delicate hose materials during installation and use.
