Product Number: HGZ340BP
For workshops standardising on one clip brand across the fleet, batch consistency matters as much as the clip itself.
This is the 310-340mm 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.
Made from heavily electro zinc plated and passivated mild steel, tested to EN9227, it suits general purpose work in non-corrosive environments. The 5-clip bulk format suits maintenance teams and assemblers fitting the same size daily. Measure the fitted outside diameter of the hose, seat the clip centrally on the barb, and recheck after sustained vibration.
Also available - the 290-320mm size (HGZ320BP); the 330-360mm size (HGZ360BP); a 304 stainless version in the same size and pack (HGS340BP).
Few clips at this level carry a Kitemark, NATO approval and 180-plus years of British manufacturing behind them.

A. It adjusts between 310-340mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 310-340mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps.
A. JCS recommends 6.0 Nm (54 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. 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. Start from the application, as JCS's own guidance does: what the hose carries, the temperature and pressure involved, and whether the environment is corrosive. Dry, general duty points to this zinc plated clip; wet, salty or chemical exposure points to the stainless range. Then size by the fitted hose diameter.
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 5 clips, all 310-340mm adjustment range. Other pack formats of the same clip are listed separately.
