Why Jubilee® Leads the Industry
🔧 Precision Worm Drive Engineering
The signature Jubilee® worm drive mechanism provides infinite adjustment within the size range, ensuring optimal clamping force without over-compression. The precision-cut thread delivers smooth, controlled tightening and prevents band slippage under vibration.
🛡️ Marine-Grade 304 Stainless Steel
Manufactured from premium 304 stainless steel (18% chromium, 8% nickel), this clip offers superior resistance to atmospheric corrosion, moisture, and chemical exposure. Ideal for outdoor installations, marine environments, and food-grade applications.
⚙️ Universal Compatibility
The 158–190mm diameter range accommodates a wide variety of hose and pipe assemblies, from large-bore air compressor lines to industrial coolant systems. The 12.7mm band width distributes clamping pressure evenly, protecting hose integrity.
🔄 Field-Proven Reliability
Jubilee® clips have been the professional's choice since 1921. This Size 7.5 variant is engineered for heavy-duty applications where vibration, thermal cycling, and environmental exposure demand uncompromising performance.
Professional Applications
Air compressor discharge lines, receiver connections, intercooler hoses
Coolant hoses, turbo ducting, fuel lines, radiator connections
Chemical transfer, water treatment, HVAC, food & beverage
Bilge pumps, engine cooling, deck wash systems, saltwater environments
Irrigation systems, spray rigs, hydraulic implements
General hose repair, emergency fixes, equipment servicing
Installation Best Practices
- Hose Preparation: Ensure hose ends are clean, dry, and free from damage or contamination.
- Fitting Engagement: Push hose fully onto barbed or serrated fitting until it reaches the stop.
- Clip Positioning: Position clip 5–10mm back from hose end, centered over the barb or serration.
- Tightening Sequence: Tighten worm screw gradually using a flat-blade or 7mm socket driver. Apply 4–5 Nm torque.
- Inspection: Check for uniform band contact around the full circumference. Hose should not bulge or twist.
- Pressure Test: Pressurize system gradually and inspect for leaks before full operation.

Hose Compatibility Guide
Size 7.5 clips are optimized for hoses with the following outside diameters:
- Minimum OD: 158mm (6.22") – use at maximum tightness
- Optimal Range: 165–185mm (6.5"–7.28") – ideal clamping zone
- Maximum OD: 190mm (7.48") – use at minimum tightness
Note: For hoses at the extreme ends of the range, consider the next size up or down for optimal clamping force and band engagement.

UK Stock – Fast Dispatch
All Jubilee® clips are held in our UK warehouse for same-day dispatch on orders placed before 2 PM. We ship via tracked courier services to ensure your components arrive quickly and safely.
Maintenance & Care
- Periodic Inspection: Check clip tightness every 6–12 months in high-vibration environments.
- Re-torque: If hose material has compressed, re-tighten to specification.
- Cleaning: Wipe with clean cloth; avoid abrasive cleaners that may scratch stainless finish.
- Storage: Store in dry conditions; stainless steel is corrosion-resistant but not corrosion-proof in extreme environments.
