Jubilee® O Clips Size 0709
Professional Two-Ear Clamps for Precision Pneumatic Connections
Why Jubilee® O Clips Are the Professional's Choice
When pneumatic connections demand absolute reliability, Jubilee® O Clips deliver uncompromising performance. Engineered with precision two-ear clamping technology, these professional-grade fasteners provide 360° uniform compression around the entire hose circumference—eliminating the weak points and pressure inconsistencies common with traditional worm-drive clamps.
The Size 0709 is specifically designed for 7–9mm diameter applications, making it ideal for small-bore pneumatic hoses, fuel lines, coolant systems, and precision instrumentation connections where space is limited and reliability is non-negotiable.
Technical Advantages
🔧 Two-Ear Clamping Technology
Dual compression ears distribute clamping force evenly, creating a gas-tight seal without crushing or deforming thin-walled hoses.
⚡ Single-Action Installation
Install in seconds using standard pincer tools—no threading, no adjustment, no slippage. Once crimped, the connection is permanent and tamper-proof.
🛡️ Corrosion-Resistant Finish
Zinc-plated steel construction resists rust and oxidation in workshop environments, ensuring long-term durability even in humid or chemical-exposed conditions.
📐 Precision Sizing
Manufactured to tight tolerances for consistent clamping diameter—no guesswork, no over-tightening, no hose damage.
Common Applications
- Pneumatic Air Lines: Low-pressure air tool connections, compressor manifolds, and quick-coupler assemblies
- Automotive Systems: Fuel injection hoses, vacuum lines, coolant bypass tubes, and breather hoses
- Hydraulic Circuits: Low-pressure return lines and reservoir connections
- Instrumentation: Sensor tubing, sampling lines, and analytical equipment connections
- Marine & Outdoor: Bilge pump hoses, washdown systems, and portable equipment

Installation Best Practices
- Select the Correct Size: Measure the outer diameter of your assembled hose and fitting. The O-clip should slide over the connection with minimal resistance.
- Position the Clip: Slide the O-clip over the hose end, positioning it so both ears are accessible and the band sits squarely over the barb or fitting ridge.
- Crimp Both Ears: Using O-clip pincer pliers, compress each ear fully until it flattens and locks. You'll feel a distinct "snap" as the ear closes.
- Inspect the Connection: Verify that the band has contracted evenly around the hose and that no gaps or twists are visible.
- Pressure Test: Before putting the system into service, pressure-test the connection to your working pressure plus 50% safety margin.
Pro Tip: For critical applications, apply a thin film of compatible lubricant to the hose before sliding it onto the fitting—this ensures even seating and prevents hose tearing during installation.

Compatibility & Sizing Guide
The Size 0709 O-clip is designed for hose outer diameters between 7.0mm and 9.0mm when fitted over a barbed or stepped fitting. For best results:
- Hose ID should be slightly smaller than fitting OD for a snug push-fit
- Hose wall thickness typically 1.5–2.5mm for pneumatic applications
- Fitting barb or ridge should be positioned 8–12mm from hose end
