Peter Huber Metal Hose Connection Tubing, NW20 M30x1.5, 150cm

The Peter Huber 6386 is an industrial-grade insulated metal hose engineered for high-performance thermoregulation in demanding laboratory and pilot plant environments. Featuring a nominal width of NW20 and M30x1.5 threaded connections, this tubing is designed to facilitate high flow rates while maintaining exceptional thermal stability. It is built to withstand extreme temperature fluctuations ranging from -100 to 350°C, making it an essential component for high-temperature reactors, autoclaves, and large-scale distillation units. At 150cm in length, this hose provides a robust and efficient connection for medium-to-long reach setups, ensuring a secure link between your Huber Unistat and external applications.

This insulated metal hose is specifically optimized to prevent heat loss and protect personnel from the extreme surface temperatures of the internal bellows. The silicone outer cover not only provides additional insulation but also acts as a safety barrier and creates an easy-to-clean surface. The M30x1.5 fittings provide a standardized, vibration-resistant, and leak-free connection, ensuring long-term reliability for continuous industrial operations where precision and safety are paramount.

Frequently Asked Questions

1. Why is the NW20 width important for high-temperature systems?
The NW20 (20mm internal diameter) provides a larger flow cross-section than NW12 hoses. This reduces pressure drop and allows the circulation pump to maintain higher flow rates, which is essential for uniform temperature control in larger external jackets.

2. Can this hose be used for cryogenic applications?
Yes. With a rating down to -100°C, it is perfectly suited for ultra-low temperature tasks. The silicone cover and specialized insulation prevent ice formation on the outside of the hose, keeping the workspace dry.

3. What is the benefit of the 150cm length?
The 1.5-meter length is ideal for setups where the circulator is located near the application but requires enough slack to route the hose safely around other equipment or through fume hood ports.

4. Is it compatible with all Huber Unistats?
It is compatible with any Huber unit equipped with M30x1.5 connections. If your unit uses larger M38 or smaller M24 threads, Huber offers specialized adapters to ensure a secure fit.

5. What maintenance is required for this hose?
Regularly inspect the threaded connections for tightness and the silicone outer jacket for any signs of physical damage or thermal degradation. The smooth surface can be wiped clean of chemical splashes to maintain its safety properties.
