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 HGS20PM1 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. For this size band JCS publishes a recommended torque of 3.0 Nm (26 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.
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. 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.
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 5 clips, all 13-20mm adjustment range. Other pack formats of the same clip are listed separately.
