Peter Huber Metal Hose Connection Tubing, NW20 M30x1.5, 300cm

The Peter Huber is a premium-grade flexible metal hose designed for high-performance thermoregulation in demanding laboratory and industrial environments. This tubing features a nominal width of NW20 and is equipped with M30x1.5 threaded connections, ensuring a secure and reliable fit for medium-to-high flow systems. Engineered to withstand extreme thermal conditions, it supports a maximum working temperature of up to 350°C, making it an essential accessory for high-temperature reactors, distillation units, and pilot plant setups. At 300cm in length, this hose provides exceptional reach and flexibility for complex laboratory configurations while maintaining the structural integrity required to handle high-pressure thermal fluids.

Key Features:

• Brand: Peter Huber
• Connection Type: NW20 with M30x1.5 threading
• Length: 300 cm (3 meters)
• Maximum Temperature: Up to 350°C
• Material: High-quality flexible stainless steel/metal construction for superior chemical and thermal resistance
• Application: Optimized for external closed-loop thermoregulation with high-temperature circulators
• Compatibility: Designed for Huber Unistats and other high-capacity circulation thermostats requiring M30 connections

This metal hose is specifically designed to minimize flow resistance while preventing the degradation common in polymer-based tubing when exposed to extreme silicone oils or synthetic heat transfer fluids. The 3-meter length offers versatility for connecting equipment across larger distances or within walk-in fume hoods. Its robust construction ensures a long service life and maintains the safety of your temperature control process even under continuous high-heat operation.

Frequently Asked Questions

1. Why is a metal hose necessary for temperatures up to 350°C?
Standard plastic or rubber hoses will melt or become dangerously brittle at high temperatures. Metal hoses maintain their structural integrity and flexibility even at the 350°C limit of high-performance thermal fluids.

2. Does the 300cm length affect heating or cooling performance?
Longer hoses can lead to slightly higher heat loss to the environment. For optimal efficiency at 350°C, it is highly recommended to use Huber's specialized thermal insulation sleeves over the entire 3-meter length.

3. Can I use this hose with M16 or M24 connections?
This hose uses M30x1.5 threads. To connect it to units with different thread sizes, you will need the appropriate Huber thread adapters (e.g., M30 to M24 or M30 to M16).

4. Is this hose suitable for use with flammable thermal fluids?
Yes, the metal construction is non-combustible and designed to safely contain flammable high-temperature silicone oils within a closed-loop system.

5. How flexible is the NW20 metal hose?
While more rigid than small-bore plastic tubing, the metal bellows design provides sufficient flexibility for routing around laboratory equipment and making secure connections without kinking.
