Peter Huber Metal Hose Connection Tubing, NW12 M24x1.5, 200cm

The Peter Huber 6786 is an ultra-high-temperature insulated metal hose designed for extreme thermoregulation from -120°C up to 400°C. Featuring a nominal width of NW12 and M24x1.5 connections, this 200cm hose is essential for aerospace testing and specialized chemical synthesis where standard 350°C hoses fail. Constructed from 1.4404 stainless steel with specialized high-performance multi-layer insulation and a smooth silicone jacket, it provides a versatile 2-meter reach while ensuring maximum personnel protection at extreme temperatures.

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 400°C internal temperatures. The M24x1.5 fittings ensure a secure, vibration-resistant, and leak-free connection for 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 6786 model is achieved through specialized materials and construction, allowing for the use of ultra-high-temperature thermal fluids required in advanced material testing.

2. Can I use this hose for cryogenic applications?
Yes, the 6786 is rated down to -120°C. The specialized insulation and silicone jacket effectively prevent ice and frost formation on the exterior, protecting the equipment and laboratory workspace.

3. How does the 200cm length benefit my system?
The 2-meter length is the standard "versatile" choice. it provides enough slack to route the hose through fume hood ports or around lab obstacles while maintaining a high level of thermal efficiency.

4. 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, care should be taken to avoid sharp bends that could stress the internal stainless steel bellows at extreme temperatures.

5. Is this hose compatible with my Huber Unistat?
This hose uses M24x1.5 connections common on many mid-to-large Unistat models. If your unit uses larger M30 or M38 connections, Huber offers specialized thread adapters to ensure a safe and secure fit.
