Q 1. Which hose diameter does the HGZ16BP suit?

A. It adjusts between 11-16mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 11-16mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps. In imperial terms that is roughly 7/16 to 5/8 in, covering common 1/2 and 5/8 in hose sizes.

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

A. For this size band JCS publishes a recommended torque of 3.0 Nm (26 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. 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.

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. 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. 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 11-16mm adjustment range. Other pack formats of the same clip are listed separately.

Q 8. What payment methods do you accept?

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

Q 9. When will my order be dispatched?

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