Peter Huber Metal Hose Connection Tubing, NW20 M30x1.5, 100cm

The Peter Huber 6426 is an industrial-grade insulated metal hose engineered for extreme temperature thermoregulation from -100°C up to 350°C. Featuring a robust NW20 nominal width and M30x1.5 threaded connections, this 100cm hose is designed for high-flow capacity and minimal heat loss. Constructed from premium 1.4404 stainless steel with specialized multi-layer insulation and a smooth silicone jacket, it is the ideal solution for high-capacity Unistats and reactors requiring a compact, high-efficiency connection.

Key Features:

• Brand: Peter Huber
• Connection Type: NW20 with M30x1.5 threading (Sleeve nut according to DIN 3870)
• Length: 100 cm (1 meter)
• Temperature Range: Extreme versatility from -100°C to 350°C
• Material: High-grade 1.4404 stainless steel for superior chemical and thermal resistance
• Insulation: Multi-layer thermal insulation with a smooth white silicone cover and protective silicone end caps
• Pressure Rating: Maximum operating pressure of 16 bar at 20°C (10 bar at 350°C)

• Safety: Flame-resistant construction (UL94-HB) designed to protect personnel from high surface temperatures

This insulated metal hose is specifically optimized for high-performance temperature control where thermal integrity and personnel safety are paramount. The integrated silicone cover ensures a non-porous, "wipe-clean" surface that is resistant to aggressive laboratory chemicals. Its M30x1.5 fittings provide a standardized, vibration-resistant, and leak-free connection for long-term reliability in demanding research and pilot plant environments.

Frequently Asked Questions

1. Why is the 100cm length beneficial for my application?
Shorter hoses (1 meter) minimize the volume of thermal fluid required in the system and reduce the "dead volume" in the connection. This leads to faster response times and significantly less heat loss between the circulator and your external reactor.

2. Can this hose be used for cryogenic cooling?
Yes, it is rated down to -100°C. The specialized multi-layer insulation prevents the formation of ice and frost on the exterior of the hose, keeping your workspace dry and safe.

3. What is the benefit of the NW20 width?
The NW20 (20mm internal diameter) provides a larger flow cross-section than NW12 hoses, reducing backpressure and allowing the circulation pump to maintain the high flow rates necessary for large-scale applications.

4. Is the silicone outer jacket easy to maintain?
Yes. The smooth surface is designed to be "wipe-clean," making it easy to remove any accidental spills of thermal fluid. This prevents the buildup of residues that could smoke when the hose reaches its 350°C limit.

5. Will this hose fit my Huber Unistat?
This hose is designed for Unistats equipped with M30x1.5 outlets. For units with larger M38 or smaller M24 threads, Huber offers high-flow adapters to bridge the connection securely.
