Peter Huber Hose Connection Tubing, Metal NW 12 M24x1.5, 100 cm, 350°C Max. Temp.

The Peter Huber 9274 is a premium, ultra-high-temperature insulated metal hose designed for the most rigorous laboratory and pilot plant thermoregulation requirements. Featuring a nominal width of NW12 and robust M24x1.5 threaded connections, this flexible tubing is engineered to handle extreme thermal environments, supporting an expansive working temperature range from -100°C up to 350°C. This exceptional range makes it an essential accessory for high-temperature reactors, autoclaves, and distillation units where standard hoses would fail. At 100cm (1 meter) in length, it provides a compact, high-efficiency connection that minimizes "dead volume" and heat loss between the circulator and the application. The hose is constructed from high-grade 1.4404 stainless steel and features advanced multi-layer thermal insulation protected by a smooth, wipe-clean silicone outer jacket and safety end caps.

This insulated metal hose is specifically optimized for high-performance temperature control units where thermal integrity and personnel safety are paramount. The integrated silicone cover ensures a non-porous surface that is easy to clean and resistant to aggressive laboratory chemicals. The M24x1.5 fittings provide a standardized, vibration-resistant, and leak-free connection, commonly found on mid-range Huber Unistat systems, ensuring long-term reliability in demanding research 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 tasks?
Yes, it is rated down to -100°C. The specialized multi-layer insulation is highly effective at preventing the formation of ice and frost on the exterior of the hose, keeping your laboratory workspace dry and preventing water damage to sensitive components.

3. How does the M24x1.5 connection differ from M16x1?
M24x1.5 is a larger, more robust connection typically found on high-capacity Huber Unistats. It allows for higher pressure ratings (up to 16 bar) and is better suited for the higher pump capacities found in industrial-scale laboratory equipment.

4. Is the silicone outer jacket safe to touch at 350°C?
While the silicone jacket significantly reduces surface temperature to prevent immediate burns, caution is always advised at 350°C. The insulation is designed to keep the outer surface much cooler than the internal fluid, protecting personnel from the extreme heat of the internal metal bellows.

5. Will this hose fit my Huber Unistat?
Many Unistat models use M24x1.5 connections as standard. If your specific unit uses larger M30 or M38 threads, Huber offers high-flow adapters to allow the secure use of this NW12 hose.
