Q 1. Which hose diameter does the HGZ45RP suit?

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 HGZ45RP 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. What torque should the HGZ45RP be tightened to?

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. Can I use this clip on a boat?

A. No - JCS itself cautions that zinc-coated clamps can quickly corrode or seize around salt water. The marine specification is Hi-Grip Stainless: 18/8 304 stainless throughout, with Lloyd's Register Type Approval.

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

A. JCS recommends asking three questions: what is the hose carrying (water, fuel, chemicals, air)? What pressure and temperature will it see? And is the environment corrosive? The answers drive material choice - zinc plated for general non-corrosive use, stainless for corrosive environments - then match the clip's range to the fitted hose diameter.

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 10 clips, all 35-45mm 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.
