Product Number: HGS320BP
Around water - pumped, sprayed or salt-laden - clip corrosion is the failure mode; the cure is marine-quality stainless in every component.
The HGS320BP is a Hi-Grip worm drive clip adjusting between 290-320mm. Its band edges are fully rounded to protect the hose, and the hex screw is cold-headed and work-hardened with rolled threads, so it resists slipping or rounding under the driver. Tighten incrementally to the recommended 6.0 Nm (54 lb-in); over-tightening is what damages hoses. The range is manufactured to exceed BS5315 and carries the BSI Kitemark and NATO approval.
At 5 clips per box this is the standardisation format for treatment works, boatyards and pump engineers. Specification: 304 stainless (EN 1.4301) throughout, verified by salt mist testing, Lloyd's Register Type Approved. Size each joint by the fitted outside diameter of the hose and tighten in stages to the recommended torque.
Also available - the 270-300mm size (HGS300BP); the 310-340mm size (HGS340BP); a zinc plated version in the same size and pack (HGZ320BP).
All-stainless construction verified by salt mist testing - made and batch-tested in-house in Sudbury, Suffolk under ISO 9001:2015.

A. This size spans 290-320mm of fitted hose outside diameter. Measure the hose over its fitting, not the bare bore - anywhere inside 290-320mm and the HGS320BP is the right clip. One JCS size covers a span that would take two fixed nut-and-bolt clamps.
A. JCS recommends 6.0 Nm (54 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. No mixed metals here - band, housing and screw are all the same stainless grade, and JCS verifies that through salt mist testing. Cheaper clips often pair a stainless band with a plated screw, which is the part that fails 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. 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.
A. This is a pack of 5 clips, all 290-320mm adjustment range. Other pack formats of the same clip are listed separately.
A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
