Product Number: HGS340BP
Treatment works, pump fleets and boatyards buy stainless clips by the box because everything plated eventually seizes around water.
This is the 310-340mm size of the Hi-Grip worm drive range. Where cheaper clips cut their threads and leave sharp band edges, JCS rolls the screw threads for strength and fully rounds the band edges so the hose is protected as the clip bites. JCS publishes a recommended torque of 6.0 Nm (54 lb-in) for this size - seat the clip centrally on the barb and work up to it gradually. Hi-Grip exceeds BS5315 and holds BSI Kitemark and NATO approvals.
Built from 18/8 marine-quality 304 stainless steel and Lloyd's Register Type Approved, this is the clip for joints that live wet. The 5-clip bulk pack keeps a full circuit's worth - and its spares - in one box. Measure the hose's fitted outside diameter, pick the range that covers it, and recheck after high-vibration service.
Also available - the 290-320mm size (HGS320BP); the 330-360mm size (HGS360BP); a zinc plated version in the same size and pack (HGZ340BP).
An industry-standard marine clip, sized by honest adjustment ranges and backed by over 180 years of British manufacturing.

A. It adjusts between 310-340mm. Measure the outside diameter of your hose when fitted over its pipe or fitting - if that measurement falls within 310-340mm, this clip fits. JCS clips offer a larger adjustment range per size than typical nut-and-bolt clamps.
A. For this size band JCS publishes a recommended torque of 6.0 Nm (54 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 310-340mm 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.
