A. This size spans 45-60mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 45-60mm and the HGZ60BG is the right clip. One JCS size covers a span that would take two fixed nut-and-bolt clamps. In imperial terms that is roughly 1 3/4 to 2 3/8 in, covering common 2 in hose sizes.
A. For this size band JCS publishes a recommended torque of 6.0 Nm (54 lb-in). Work up to it gradually with the clip seated centrally on the barb; going past it risks damaging the hose rather than improving the seal.
A. JCS electro zinc plates and passivates the mild steel band after it is cut to size, so even the cut edges carry coating - and the finish is tested to EN9227. That suits dry and general duty; once salt or standing moisture is involved, the stainless range is the correct specification.
A. No - JCS itself cautions that zinc-coated clamps can quickly corrode or seize around salt water. The marine specification is Hi-Grip Stainless: 18/8 304 stainless throughout, with Lloyd's Register Type Approval.
A. Anywhere a flexible hose seals onto a rigid fitting in dry or general conditions - vehicles, garden and grounds machinery, air lines, workshop and light industrial pipework. JCS supplies the automotive sector and leading agricultural machinery manufacturers.
A. The screw is cold-headed and work-hardened with a sharply defined hexagon and rolled threads to resist slipping and rounding. For high-vibration applications JCS recommends rechecking the clip after use to maintain seal integrity.
A. This is a pack of 5 clips, all 45-60mm adjustment range. Other pack formats of the same clip are listed separately.
