Q 1. Which hose diameter does the HGZ70BP suit?

A. It adjusts between 50-70mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 50-70mm, this clip fits. JCS clips offer a larger adjustment range per size than typical 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.

Q 2. Can you over-tighten a hose clip?

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.

Q 3. Are zinc plated hose clips rust resistant?

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.

Q 4. Can I use this clip on a boat?

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.

Q 5. What are these clips used for?

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.

Q 6. Will vibration loosen this clip?

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.

Q 7. How many clips are in this pack?

A. This is a pack of 10 clips, all 50-70mm adjustment range. Other pack formats of the same clip are listed separately.

A. Yes - WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.

A. We accept all major credit and debit cards, along with PayPal.
