Testo 5m Silicone Connection Hose for Pitot Tubes

This Testo silicone connection hose is a crucial link for accurate airflow measurements, designed to connect your Pitot tube to a pressure probe without leaks. At 5 metres long, it gives you the reach needed for those tricky rooftop or ceiling void installs.

Running tight lines for duct pressure or velocity readings in Australian conditions means you need reliable connections that won't kink or crack under a bit of sun. This hose handles up to 700 hPa, perfect for typical HVAC applications.

Best For

• HVAC technicians
• Airflow balancing specialists
• Building commissioning teams
• Anyone performing duct velocity or static pressure tests

Compatibility

This 5-metre silicone hose is specifically designed for connecting Pitot tubes (like the Testo 0635 series) to compatible pressure probes or differential pressure measuring instruments. Its 7mm outer diameter ensures a snug fit for most standard Pitot tube connections.

If you're running a different model, check fittings and specs before ordering.

Features

• Flexible Silicone Construction: Ensures durability and resistance to kinking, even in tight spaces.
• Generous 5m Length: Provides ample reach for testing in large ducts or elevated positions.
• Pressure Rated to 700 hPa (281 inH₂O): Suitable for a wide range of HVAC airflow and static pressure measurements.
• Standard 7mm Diameter: Ensures compatibility with common Pitot tubes and pressure probes.
• Lightweight Design: At only 154g, it won't add significant bulk to your measurement kit.

Using It on the Job

1. Check for Damage: Before each use, inspect the hose for any cuts, cracks, or kinking that could affect readings.
2. Connect Securely: Firmly attach one end to your Pitot tube and the other to your differential pressure probe or manometer. Ensure a leak-free connection.
3. Calibrate Your Instrument: Perform any necessary zeroing or calibration procedures on your pressure instrument before taking measurements.
4. Avoid Kinks: Route the hose carefully to prevent sharp bends that could restrict airflow and give inaccurate readings.
5. Clean After Use: Wipe down the hose with a damp cloth if it gets dirty to maintain its condition.

Limitations & Safety Notes

• Only for use with non-corrosive, non-condensing gases and within its specified pressure rating.
• Not suitable for high-pressure pneumatic or hydraulic systems.
• Avoid exposing the hose to sharp objects or abrasive surfaces to prevent damage.
• Always follow the operating instructions for your Pitot tube and pressure measurement device.

Tradie Pro Tip

When you're trying to measure airflow in a tight duct run, especially in a ceiling space on a hot day, a flexible silicone hose like this is a lifesaver. Keep it coiled neatly in your kit so it doesn't get stretched or damaged.
