Peter Huber Hose Connection Tubing, Metal NW 12 M16x1, 150 cm, 200°C Max. Temp.

The Peter Huber 9609 is a high-performance insulated metal hose designed for safe and efficient thermoregulation in laboratory environments. Featuring a nominal width of NW12 and M16x1 threaded connections, this flexible tubing is specifically engineered to handle the thermal demands of heating and cooling circulators. It supports a reliable working temperature range from -50 to 200°C, making it suitable for a wide variety of standard temperature control tasks involving silicone oils and other common thermal fluids. At 150cm in length, this hose provides a compact connection for circulators to external reactors, photometers, or viscometers. The hose is constructed from durable stainless steel and features specialized insulation with a smooth silicone outer cover and protective end caps to minimize heat loss and ensure user safety.

This Huber metal hose is a critical accessory for maintaining the precision and safety of your temperature control circuit. The integrated silicone cover not only provides additional insulation but also creates a "wipe-clean" surface that is resistant to chemical splashes. The M16x1 fittings are standardized for a secure, vibration-resistant connection to Huber Ministat, KISS, and Compatible Control (CC) series units, ensuring long-term reliability in daily laboratory operations.

Frequently Asked Questions

1. Why should I use an insulated hose for 200°C applications?
At 200°C, non-insulated hoses lose significant heat to the environment, which forces your circulator to work harder and reduces temperature accuracy at the application. More importantly, the insulation and silicone cover protect laboratory staff from severe burns.

2. Can this hose be used for sub-zero cooling?
Yes, the hose is rated down to -50°C. The specialized insulation prevents the formation of ice and frost on the outside of the hose, which protects the laboratory workspace from water damage and maintains cooling efficiency.

3. What does the "M16x1" connection signify?
M16x1 refers to a metric thread with a 16mm diameter and a 1mm pitch. This is a very common connection size for smaller Huber circulators like the Ministat and KISS series. Always verify your unit's outlet size before ordering.

4. Is there a risk of the hose kinking?
The metal bellows design is quite flexible, but it does have a minimum bending radius of 120 mm. Bending the hose more sharply than this can damage the internal structure and lead to leaks or restricted flow.

5. Is this hose compatible with flammable thermal fluids?
Yes, the stainless steel construction and high-temperature rating make it suitable for use with flammable heat transfer fluids, provided they are used within a closed-loop system and within the hose's temperature specifications.
