Peter Huber Metal Hose Connection Tubing, NW12 M24x1.5, 300cm

The Peter Huber 6787 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, deep-vacuum distillation, and aerospace testing where standard 350°C hoses cannot maintain integrity. At 300cm (3 meters) in length, it provides maximum reach for complex laboratory configurations. 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 and thermal efficiency.

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 rated to 350°C. The 400°C rating of the 6787 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 6787 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 3-meter length affect performance?
Longer hoses inherently increase the surface area for potential heat loss. However, the premium insulation is designed to minimize this, ensuring that the maximum amount of heating or cooling power reaches your application.

5. Is this hose compatible with my Huber Unistat?
This hose uses M24x1.5 connections. Many mid-range and large 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.
