Q 1. What size hose does the HGZ45BG fit?

A. This size spans 35-45mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 35-45mm and the HGZ45BG is the right clip. One JCS size covers a span that would take two fixed nut-and-bolt clamps. In imperial terms that is roughly 1 3/8 to 1 3/4 in, covering common 1 1/2 and 1 3/4 in hose sizes.

Q 2. How tight should this hose clip be?

A. For this size band JCS publishes a recommended torque of 5.0 Nm (45 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. 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. Do worm drive hose clips come loose over time?

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. How many clips are in this pack?

A. This is a pack of 50 clips, all 35-45mm adjustment range. Other pack formats of the same clip are listed separately.

Q 8. What warranty does this product come with?

A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product's tech specs or datasheet where available.
