Description
Jubilee® Original · Worm Drive Series · Size 12.5
The Industry Standard.
Engineered for Large-Diameter Demands.
For over 90 years, the Jubilee® clip has been the benchmark of clamping integrity. Size 12.5 extends that legacy to large-bore applications — delivering consistent, high-torque clamping across a 286–318mm diameter range in marine-grade 304 stainless steel.
Why Jubilee® Size 12.5
When the diameter exceeds 280mm, the margin for error disappears. Ducting failures, hose blowouts, and fluid leaks at this scale carry real operational cost. The Jubilee® Size 12.5 is purpose-built for exactly these conditions — a precision-rolled 304 stainless steel band, a self-locking worm drive mechanism, and a 20mm band width that distributes clamping load evenly across the full circumference.
Unlike generic clamps that deform under torque or corrode within a season, the Jubilee® original is manufactured to BS EN ISO 9001 standards and trusted by fleet engineers, marine contractors, and industrial maintenance teams across the UK.
Key Features- 286–318mm clamping range — precision-engineered for large-bore hoses, pipes, and ducting
- 304 stainless steel construction — resists salt, moisture, chemicals, and UV degradation
- 20mm wide band — maximises contact area for uniform, leak-free sealing
- Hex-head worm drive — compatible with standard 7mm hex drivers and screwdrivers
- −40°C to +200°C operating range — suitable for high-temperature industrial environments
- Jubilee® original brand — over 90 years of engineering heritage; not a generic imitation
- Reusable and adjustable — re-torque or reposition without replacing the clip
Typical Applications
Industrial Ducting
Securing large-bore flexible ducting in extraction, ventilation, and HVAC systems where vibration resistance is critical.
Marine & Offshore
Bilge hoses, exhaust systems, and through-hull connections in salt-water environments demanding full corrosion immunity.
Fleet & HGV Maintenance
Coolant hoses, intercooler pipes, and air intake ducting on commercial vehicles and heavy plant machinery.
Agricultural Equipment
Hydraulic and irrigation hose connections on tractors, combine harvesters, and field machinery exposed to outdoor conditions.
Installation Guide
- Confirm hose or pipe OD falls within the 286–318mm range before fitting.
- Slide the open clip over the hose end before connecting to the fitting or spigot.
- Position the clip 5–10mm from the hose end, centred over the retaining bead where present.
- Tighten the hex-head screw using a 7mm hex driver or flat-blade screwdriver to the recommended torque.
- Inspect after first pressurisation and re-torque if required — the band will seat fully under load.
