Q 1. Which hose diameter does the HGZ300BP suit?

A. It adjusts between 270-300mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 270-300mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps.

Q 2. What torque should the HGZ300BP be tightened to?

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. How well does the zinc plating resist corrosion?

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. 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 5. What are these clips used for?

A. Anywhere a flexible hose seals onto a rigid fitting in dry or general conditions - vehicles, garden and grounds machinery, air lines, workshop and light industrial pipework. JCS supplies the automotive sector and 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 5 clips, all 270-300mm 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.

Q 9. Can I ask questions about this product before ordering?

A. Yes - WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.
