Q 1. How do I know whether the HGS40RP will fit my hose?

A. It adjusts between 30-40mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 30-40mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps. In imperial terms that is roughly 1 3/16 to 1 9/16 in, covering common 1 1/4 and 1 1/2 in hose sizes.

Q 2. What torque should the HGS40RP 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. Will the screw rust before the band does?

A. Yes - every component is the same grade of stainless steel, verified through JCS's salt mist testing, so there is no mixed-metal weak point to corrode first.

Q 4. Are these suited to water and drainage plant?

A. That is one of their core applications: JCS stainless clips serve temporary and permanent pumping, stormwater and overflow systems, wastewater treatment works, and agricultural irrigation networks, where corrosion resistance decides service life.

Q 5. Is 304 stainless good enough for marine use, or do I need 316?

A. For most marine and wet industrial duty, this 304 (18/8) clip with its Lloyd's Register Type Approval is the standard answer. JCS reserves its 316 grade for the most demanding settings - offshore, food and pharmaceutical - so if that is your application, ask us about options.

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 30-40mm adjustment range. Other pack formats of the same clip are listed separately.

Q 8. What if my order arrives damaged or incorrect?

A. WhatsApp us on 07754 288583 with photos of the item and packaging.
