Q 1. How do I know whether the HGS20BP will fit my hose?

A. This size spans 13-20mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 13-20mm and the HGS20BP 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 1/2 to 13/16 in, covering common 5/8 and 3/4 in hose sizes.

Q 2. How tight should this hose clip be?

A. JCS recommends 3.0 Nm (26 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. 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. Hi-Grip 304 stainless is marine-quality 18/8 steel with Lloyd's Register Type Approval and is suited to saltwater service. JCS also makes a 316 grade for maximum corrosion resistance in the most demanding marine, offshore, food and pharmaceutical settings - contact us if your application is in that category.

Q 6. Do worm drive hose clips come loose over time?

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 10 clips, all 13-20mm 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.
