Peter Huber Metal Hose Connection Tubing, NW12 M24x1.5, 150cm

The Peter Huber 6785 is an ultra-high-temperature insulated metal hose designed for the most extreme thermoregulation requirements in advanced research and industrial pilot plants. Featuring a nominal width of NW12 and robust M24x1.5 threaded connections, this specialized tubing is engineered to handle an extraordinary temperature range from -120°C up to 400°C. This exceptional performance makes it a critical component for high-temperature reactors and aerospace testing where standard 350°C hoses cannot maintain integrity. At 150cm (1.5 meters) in length, it provides a versatile reach while maintaining high thermal efficiency. The hose is constructed from premium-grade 1.4404 stainless steel and features specialized high-performance multi-layer insulation, protected by a smooth silicone outer jacket and silicone safety end caps to ensure personnel protection.

This series of hose is specifically optimized for high-performance Huber Unistats operating at the absolute limits of thermal fluid technology. The integrated silicone cover provides a durable, easy-to-clean surface that prevents atmospheric moisture from freezing during cryogenic tasks while shielding users from the dangerous 400°C internal temperatures. The M24x1.5 fittings ensure a secure, vibration-resistant, and leak-free connection, providing long-term reliability for continuous operation in the most demanding thermal environments.

Frequently Asked Questions

1. Why is the 400°C rating significant?
Most high-end metal hoses are limited to 350°C. The 400°C rating of the 6785 model is achieved through specialized materials and construction, allowing for the use of ultra-high-temperature thermal fluids required in specific chemical synthesis and material testing processes.

2. Can I use this hose for cryogenic applications?
Yes, the 6785 is rated down to -120°C. The specialized insulation and silicone jacket are highly effective at preventing the formation of ice and frost on the exterior, protecting both the equipment and the laboratory workspace.

3. How flexible is this ultra-high-temp hose?
Due to its robust construction and thick insulation, it has a minimum bending radius of 220 mm. While flexible enough for standard routing, care should be taken to avoid sharp bends that could stress the internal stainless steel bellows at extreme temperatures.

4. Does the 150cm length affect performance?
The 1.5-meter length is an ideal mid-range choice, providing enough slack for flexible routing without creating the excessive heat loss or "dead volume" associated with longer 3-meter hoses.

5. Is this hose compatible with my Huber Unistat?
This hose uses M24x1.5 connections. Many mid-range Unistats use this size. If your unit has M30 or M38 connections, you will need the appropriate Huber thread adapters to ensure a safe and secure fit.
