Description
Genuine Jubilee® · British Engineering Since 1921 · Professional Trade Pack
Size 2A Worm Drive Hose Clip
35–50mm | 304 Stainless Steel
Box of 10 · Grade 304 Austenitic SS · BS EN 10088-2 Certified · UK Stock
The Standard
Over a Century of Clamping Precision
Since 1921, the Jubilee® worm drive clip has been the reference standard against which every other hose clip is measured. The Size 2A is the workhorse of professional workshops — engineered for the 35–50 mm diameter range that covers the majority of pneumatic discharge lines, hydraulic return circuits, and automotive cooling hoses encountered in daily trade use.
Manufactured from 304 grade austenitic stainless steel — 18% chromium, 8% nickel — these clips resist corrosion from moisture, oils, coolants, and mild process chemicals without compromise. When a connection must hold under pressure, vibration, and thermal cycling, genuine Jubilee® is the only rational choice.

Why Jubilee®
Engineering Advantages
-
✦Genuine Jubilee® manufacture — not a pattern copy. Consistent material composition, traceable quality assurance, and proven performance in critical applications worldwide.
-
✦304 stainless steel construction — 18% Cr / 8% Ni austenitic alloy delivers superior corrosion resistance in workshop, marine, and process environments.
-
✦Precision worm drive mechanism — infinite adjustment within the 35–50 mm range ensures optimal, even contact pressure around the full hose circumference.
-
✦Rolled band edges — Jubilee®'s proprietary edge treatment eliminates sharp surfaces that damage hose materials during installation or thermal cycling, extending hose service life.
-
✦Captive hex-head screw — 7 mm hex drive; screw cannot be lost during installation. Compatible with standard spanners and nut drivers.
-
✦Rated −50°C to +250°C — suitable for high-temperature automotive and industrial applications where inferior clips fail prematurely.
-
✦Professional trade pack of 10 — workshop-ready quantity for ongoing maintenance, fleet servicing, or installation projects.
Applications
Where Size 2A Performs
| Application | Typical Hose / Pipe | Notes |
|---|---|---|
| Pneumatic Systems | 32 mm rubber air hose (1¼") | Compressor discharge lines, tool supply, pressure vessel connections |
| Hydraulic Circuits | 38–50 mm reinforced hose | Low-pressure return lines, reservoir connections, filter housings |
| Automotive Workshop | 35–45 mm silicone coolant hose | Cooling systems, breather pipes, vacuum lines |
| Industrial Maintenance | 40 mm reinforced PVC | Extraction ducting, dust collection, fluid transfer |
| Marine & Coastal | 38 mm rubber / PVC | Bilge pumps, engine cooling, deck wash — 304 SS resists salt spray |
Installation
Professional Fitting Procedure
-
01
Hose Preparation
Cut hose ends square and inspect for damage. Clean the connection area to remove oils, grit, or contaminants that could compromise the seal integrity.
-
02
Clip Positioning
Slide the clip over the hose and position 6–10 mm from the hose end. Ensure the screw housing is oriented away from adjacent components. The band must sit centrally on the barbed fitting.
-
03
Tightening
Using a 7 mm spanner or nut driver, tighten progressively. Apply 3–4 Nm for standard rubber hoses; 4–4.5 Nm for reinforced hoses. Do not exceed 4.5 Nm — over-tightening cuts into hose material and voids the connection.
-
04
Post-Installation Verification
Pressurise the system gradually and inspect all connections for leaks. Re-torque after the first thermal cycle if operating above 80°C.
Service & Maintenance
Inspection Schedule
| Check | Interval | Action |
|---|---|---|
| Visual inspection | Every 6–12 months | Check for band corrosion, screw thread damage, or hose deterioration |
| Torque verification | After first thermal cycle; annually thereafter | Re-check tightness with calibrated torque driver |
| Replacement criteria | As required | Replace if band shows pitting, threads are damaged, or clip has been over-torqued |
| Expected service life | — | 5–10 years (workshop); 3–5 years (marine / coastal) |
