Peter Huber 2-Way Header M16x1 with Connection Angle

The Peter Huber 337657 is a premium 2-way manifold header designed for high-performance thermal fluid distribution across an expansive temperature range from -80°C up to 300°C. This specialized assembly features a primary M16x1 inlet that branches into two M16x1 outlets, allowing a single circulator to supply two external applications simultaneously. To facilitate installation in restricted laboratory spaces, this kit includes the #10159 connection angle, enabling a 90-degree orientation for cleaner hose routing and reduced stress on pump connections. Constructed from high-grade materials to withstand extreme thermal cycling, it is the ideal solution for parallel synthesis or multi-stage reactors requiring consistent temperature control and industrial-grade reliability.

Key Features:

• Brand: Peter Huber
• Connection Type: All ports M16x1 threaded (1 x Inlet, 2 x Outlets)
• Included Accessories: #10159 90-degree connection angle for space-saving installation
• Temperature Range: Exceptional versatility from -80°C to 300°C
• Material: High-performance metallic construction with chemical-resistant seals
• Compatibility: Optimized for Huber Ministats, KISS, and CC series units
• Application: Simultaneous parallel distribution of thermal fluid to two external devices
• Design: Robust manifold engineered for minimal pressure drop and maximum safety

This header system is specifically built for systems operating at the limits of standard laboratory equipment. The inclusion of the 90-degree adapter ensures that even in tight fume hoods or complex pilot plant setups, the fluid path remains unobstructed. Its high-temperature rating makes it compatible with nearly all synthetic thermal fluids, ensuring long-term durability without the risk of seal degradation or structural fatigue.

Frequently Asked Questions

1. Why is the -80 to 300°C range significant?
Most standard headers are limited to 140°C. This model uses specialized materials and sealing technology to remain safe and leak-proof during extreme cryogenic cooling or high-temperature heating, covering the vast majority of Unistat and CC applications.

2. What is the benefit of the #10159 connection angle?
The 90-degree angle prevents hoses from kinking or protruding too far from the back of the circulator. This is especially useful in modern laboratories where bench space is limited and equipment is often placed close to walls or inside cabinets.

3. Does this header include manual valves?
No, this is a standard open-flow header. If you require the ability to isolate each branch independently while the system is running, we recommend looking at the Huber valved manifold series (e.g., 343294).

4. How does this affect the pump performance?
Splitting the flow will divide the total liters per minute (L/min) between the two outlets. Because this header is designed for high-performance units, the internal bore is optimized to maintain high flow rates and minimize backpressure.

5. Is it compatible with silicone oils?
Yes. The materials used in the 337657 are fully compatible with silicone-based thermal fluids, as well as water-glycol mixtures and other common heat transfer media.
