The Peter Huber 6431 is a high-precision metric conversion adapter designed to bridge different connection standards within the Huber thermoregulation ecosystem. This adapter features an M16x1 female threaded port and an M30x1.5 male threaded connection. It serves as a vital interface for downsizing from larger M30 infrastructure to M16 components, or for connecting M16 male unit outlets to M30 female hoses and manifolds. Machined from premium-grade, chemical-resistant metal, it is engineered to maintain a pressure-tight seal and excellent flow characteristics across the extreme temperature ranges of high-performance laboratory circulators.
Key Features:
- Brand: Peter Huber
- Thread A: M16x1 Female (Standard for Ministat and small CC units)
- Thread B: M30x1.5 Male (Standard for NW20 Huber Unistat connections)
- Material: Durable, thermally stable metallic construction for long-term industrial reliability
- Thermal Range: Optimized for use across the wide temperature spectrum of Huber systems (-120°C to +400°C)
- Pressure Rating: Designed to withstand high pump pressures and frequent thermal cycling
- Application: Connects M16 male fittings/outlets to M30 female hoses or ports
- Flow Optimization: Precision-machined internal bore to minimize turbulence during fluid transition
This adapter is essential for laboratories that utilize a variety of Huber equipment and need to standardize their hose or manifold connections. Its robust design ensures that fluid delivery remains consistent and safe, even when transitioning between different flow diameters. The precision-cut threads minimize the risk of mechanical wear or fluid loss, protecting the integrity of your thermal experiments and equipment.
Frequently Asked Questions
1. Why would I need an M16 female to M30 male adapter?
This is commonly used if you have a circulator with an M16x1 male outlet but wish to use a larger M30x1.5 insulated hose. The M16 female side screws onto the unit, providing a male M30 interface for the hose's female swivel nut.
2. Does this adapter act as a flow restrictor?
Because the M16 side has a smaller internal diameter (NW8/NW12) than the M30 side (NW20), the flow will naturally be governed by the smaller orifice. However, the internal taper is designed to minimize turbulence during this transition.
3. Do I need O-rings for this adapter?
The M16x1 female side requires a flat gasket or O-ring to seal against the male unit outlet. The M30 male side typically seals against the gasket already present inside the M30 female hose nut. Always inspect gaskets for signs of hardening or cracking.
4. Can this be used with silicon oils at high temperatures?
Yes. The metallic construction is fully compatible with silicone-based thermal fluids, water-glycol, and synthetic thermofluids like DW-Therm across their entire operating ranges.
5. Is there a version that goes from M16 male to M30 female?
Yes, that would be Huber part number 6454. It is important to verify the "gender" of your existing threads before ordering to ensure the correct orientation for your setup.
