Q 1. How do I know whether the HGZ90BG 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. How tight should this hose clip be?

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. 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 4. 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 5. How do I choose the right hose clip?

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.

Q 6. Will vibration loosen this clip?

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.

Q 7. What does the HGZ90BG pack contain?

A. This is a pack of 10 clips, all 70-90mm adjustment range. Other pack formats of the same clip are listed separately.
