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 HGS20RP 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.
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.
A. Yes - this is the specification JCS makes for exactly that duty: 18/8 marine-quality 304 stainless with Lloyd's Register Type Approval covering marine, offshore and industrial service, suited to salt water and other highly corrosive environments.
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.
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.
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.
A. This is a pack of 10 clips, all 13-20mm adjustment range. Other pack formats of the same clip are listed separately.
