Product Number: HGZ12PM2
Variations
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 9.5-12mm 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 3.0 Nm (26 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.
The band is mild steel, heavily electro zinc plated, passivated and tested to EN9227 - JCS's general purpose specification for domestic, automotive and industrial duty away from salt and standing moisture. One clip covers a wider span than a typical nut-and-bolt clamp, so fewer sizes cover more hoses. Seat it centrally over the barb when fitting.
Also available - the same clip in a 5-pack (HGZ12PM1); the 11-16mm size (HGZ16PM2).
Designed, made and batch-tested in-house at Sudbury, Suffolk under ISO 9001:2015 - an everyday clip built to an approval list most premium clips cannot match.

A. This size spans 9.5-12mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 9.5-12mm and the HGZ12PM2 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 3/8 to 1/2 in, covering common 3/8 in hose sizes.
A. JCS recommends 3.0 Nm (26 lb-in) for this size. Position the clip centrally over the hose barb and tighten incrementally to that torque - over-tightening can damage the hose.
A. The band is heavily electro zinc plated and passivated, tested to EN9227, and JCS plates the steel after cutting so the cut edges are coated too. It is intended for non-corrosive environments such as domestic and light industrial use - for wet, salty or chemical-exposed duty choose the Hi-Grip Stainless version.
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. The zinc plated Hi-Grip is JCS's general purpose worm drive clip for domestic, automotive and industrial hose connections in non-corrosive environments. JCS clips are used across the automotive sector and by 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 9.5-12mm adjustment range. Other pack formats of the same clip are listed separately.
A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product's tech specs or datasheet where available.
