A leaking hose joint on a mower, compressor or van engine usually traces back to one part - the clip that stopped gripping.
This is the 50-70mm size of the Hi-Grip worm drive range. Where cheaper clips cut their threads and leave sharp band edges, JCS rolls the screw threads for strength and fully rounds the band edges so the hose is protected as the clip bites. JCS publishes a recommended torque of 6.0 Nm (54 lb-in) for this size - seat the clip centrally on the barb and work up to it gradually. Hi-Grip exceeds BS5315 and holds BSI Kitemark and NATO approvals.
Uniquely, JCS applies the zinc plating after the steel is cut, so even the cut edges of the band are coated. That makes it a dependable general purpose clip for domestic, automotive and industrial use in non-corrosive conditions. Size it by the fitted outside diameter of the hose, and recheck after sustained vibration - the 10-clip pack keeps spares on hand for the next service.
Also available - the same clip as a trade bag (HGZ70BG); the same clip as a bulk pack (HGZ70BP); the 45-60mm size (HGZ60RP); a 304 stainless version in the same size and pack (HGS70RP).
Few clips at this level carry a Kitemark, NATO approval and 180-plus years of British manufacturing behind them.

A. This size spans 50-70mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 50-70mm and the HGZ70RP 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 15/16 to 2 3/4 in, covering common 2 and 2 1/2 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. JCS advises against zinc plated clips in marine conditions, where they can corrode or seize. For boats and other saltwater environments use Hi-Grip Stainless, which is 18/8 marine-quality 304 stainless steel 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. JCS designs against it: the hex screw is cold-headed and work-hardened with rolled threads, so it holds its setting and will not round off. On high-vibration equipment, JCS's guidance is to recheck the clip after service to keep the seal intact.
A. This is a pack of 10 clips, all 50-70mm adjustment range. Other pack formats of the same clip are listed separately.
