Also known as Serflex, the hose clamp creates sufficient and radially proportional force around the outer circumference of the hose, preventing leaks between the fitting and the hose. Our 8 mm open band hose clamp offers a wide clamping range. It is manufactured according to the NF E 27 851 standard certified by AFNOR. +Stainless steel hose clamp with openwork band 32-52 mm SOLD IN PACKS OF 3 CLAMPS The openwork in the band provides great flexibility and allows for compensation for common pipe thickness tolerances. The screw is machined so that the angle of attack of its serrations is perfectly perpendicular to the openwork and thus the band does not slip. The hexagonal screw head allows for assembly and disassembly using standard tools.
