Q 1. How do I know whether the HGZ90BP will fit my hose?

A. It adjusts between 70-90mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 70-90mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps. In imperial terms that is roughly 2 3/4 to 3 9/16 in, covering common 3 and 3 1/2 in hose sizes.

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

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.

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. Is a zinc plated clip OK for marine use?

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. Where are zinc Hi-Grip clips typically fitted?

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. Do worm drive hose clips come loose over time?

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 70-90mm adjustment range. Other pack formats of the same clip are listed separately.

Q 8. When will my order be dispatched?

A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
