Technical Specifications

Constant tension worm-drive clips are designed to be used primarily in the automotive sector.

The main difference between the W4 constant tension worm-drive and the standard Mikalor worm-drive is to be found in the spring-loaded insert.

This spring-loaded insert maintains constant pressure around the hose in case of variations in temperature and /or vibration thereby guaranteeing performance far superior to conventional worm-drives.

For this reason constant tension worm-drive clips are used mainly with tubes carrying hot air in turbo compressor applications or on engine refrigeration systems.

Moreover, the cold-formed stamped band thread, smoothed on the underside, combined with the beveled band edges protects the hose from any damage.

ASFA W4 CT worm-drive clips are manufactured entirely from stainless steel (AISI 304) thereby ensuring excellent corrosion resistance.

This clip complies fully with the DIN 3017 norm and also with the RoHs directive EU/2002/95/EC dated 1st July 2006.

* The maximum application pressure can vary depending on the type of hose used and the geometry of the coupling.

* The Nominal Ø “A” does not take into account the spring-loaded insert.
