Peter Huber Metal Hose Connection Tubing, NW12 M16x1, 200cm

The Peter Huber 6136 is a high-performance, ultra-high-temperature insulated metal hose designed for the most demanding thermoregulation tasks in research and industrial laboratories. Featuring a nominal width of NW12 and standard M16x1 threaded connections, this flexible tubing is engineered to handle extreme thermal environments, supporting a wide working temperature range from -100°C up to 350°C. This exceptional range makes it an essential accessory for high-temperature reactors, distillation units, and pilot plant setups where standard 200°C hoses would fail. At 200cm (2 meters) in length, it provides a versatile reach for connecting circulators to external applications while maintaining a high degree of thermal efficiency. 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. Its M16x1 fittings are compatible with Huber's Ministat, KISS, and smaller CC series, providing a vibration-resistant, leak-free connection capable of withstanding the high pressures of modern circulation pumps even at extreme temperatures.

Frequently Asked Questions

1. Why is this hose rated for 350°C when other M16 hoses are only rated for 200°C?
The 6136 model uses upgraded internal stainless steel bellows and high-specification insulation materials that do not degrade at extreme heat levels, providing a much higher safety margin and operational range than standard hoses.

2. Can I use this hose for cryogenic cooling?
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 safe.

3. How does the 200cm length affect my system's efficiency?
The 2-meter length is the standard choice for most laboratory setups, providing enough slack for routing into fume hoods without creating excessive "dead volume" or significant heat loss compared to longer 3-meter hoses.

4. Is the silicone outer jacket easy to maintain?
Absolutely. The smooth surface is designed to be "wipe-clean," making it easy to remove any accidental spills of thermal fluid or chemicals, which helps prevent smoking or odors when the hose is heated to 350°C.

5. Will this hose fit my Huber Ministat or KISS unit?
Yes, as long as your unit is equipped with M16x1 outlets. It is a direct-fit upgrade for these series, offering a higher pressure rating (16 bar) than the standard 200°C rated hoses.
