Engineering Excellence
304 Stainless Steel Construction
The 304 grade austenitic stainless steel delivers exceptional corrosion resistance across diverse operating environments. With 18% chromium and 8% nickel content, these clips maintain structural integrity when exposed to moisture, oils, coolants, and mild chemicals—essential for pneumatic systems operating in industrial workshops.
Precision Worm Drive Mechanism
The signature Jubilee® worm drive system provides infinite adjustment within the 35-50mm range, ensuring optimal contact pressure distribution around the entire hose circumference. The captive hex-head screw prevents loss during installation and allows controlled tightening with standard 7mm spanners or nut drivers.
Rolled Band Edge Technology
Jubilee®'s proprietary rolled band edges eliminate sharp surfaces that could damage hose materials during installation or thermal cycling. This design feature extends hose service life and reduces the risk of premature failure in high-vibration applications.
Professional Applications
- Pneumatic Systems: Air compressor discharge lines, tool supply hoses, pressure vessel connections
- Hydraulic Circuits: Low-pressure return lines, reservoir connections, filter housing assemblies
- Automotive Workshop: Coolant hoses, breather pipes, vacuum lines, fuel system repairs
- Industrial Maintenance: Process piping, extraction systems, fluid transfer applications
- Marine & Coastal: Bilge pump connections, engine cooling systems, deck wash equipment
Installation Best Practices
1. Hose Preparation
Ensure hose ends are cut square and free from damage. Clean the connection area to remove contaminants that could compromise the seal.
2. Clip Positioning
Position the clip 6-10mm from the hose end, ensuring the screw housing sits away from potential contact points. The band should sit centrally on the barbed fitting.
3. Tightening Procedure
Tighten progressively using a 7mm spanner or nut driver. Apply 3-4 Nm torque for rubber hoses, 4-4.5 Nm for reinforced hoses. Avoid over-tightening which can damage hose materials.
4. Post-Installation Check
Pressurize the system gradually and inspect for leaks. Re-torque after initial thermal cycling if operating above 80°C.
Why Choose Genuine Jubilee®?
Over a century of British engineering heritage has made Jubilee® the benchmark for worm drive hose clips. While pattern alternatives exist, genuine Jubilee® clips deliver measurable advantages:
- Consistent material composition meeting BS EN 10088-2 standards
- Precision-rolled band edges that protect hose integrity
- Captive screw design preventing component loss
- Proven performance in critical applications worldwide
- Traceability and quality assurance documentation
Product Highlights
Compatibility Guide
Size 2A clips are optimized for the following hose and pipe specifications:
| Hose Type | Internal Diameter | Typical Application |
|---|---|---|
| Rubber Air Hose | 32mm (1¼") | Compressor discharge lines |
| PVC Layflat | 38mm (1½") | Water transfer, irrigation |
| Silicone Coolant | 35-45mm | Automotive cooling systems |
| Reinforced PVC | 40mm | Extraction, dust collection |
| Hydraulic Return | 38-50mm | Low-pressure hydraulic circuits |
⚠ Important Sizing Information
The 35-50mm range refers to the outside diameter of the hose when fitted over a barbed connection. For hoses with stated internal diameters, add approximately 3-6mm (depending on wall thickness) to determine the correct clip size. When in doubt, measure the assembled connection with calipers before ordering.
Maintenance & Service Life
While 304 stainless steel offers excellent durability, periodic inspection ensures continued performance:
- Visual Inspection: Check for band corrosion, screw thread damage, or hose deterioration every 6-12 months
- Torque Verification: Re-check tightness after initial thermal cycling and annually thereafter
- Replacement Criteria: Replace if band shows pitting, screw threads are damaged, or clip has been over-torqued
- Expected Service Life: 5-10 years in typical workshop environments; 3-5 years in marine/coastal applications
