Hello, this is VALVEPARK.
Today we will explain in simple terms one of the vacuum fittings that sounds a bit tricky but is actually very easy to understand - the Vacuum Conical Reducer!
Simply put, it is a connection fitting that bridges a larger pipe and a smaller pipe. Think of it like connecting a large straw to a small straw - this fitting is the piece in the middle that smoothly joins them together.
If pipe diameters change abruptly, air flow becomes turbulent and efficiency drops. By using a cone-shaped (gradually narrowing) design, the reducer allows air to flow smoothly between different pipe sizes.
Simply speaking, it is a metal that resists rust and is highly durable.
That is why it is widely used in factories and research laboratories.

|---|---|---|---|
| NW25-16 | 40 | 30 | 40 |
| NW40-16 | 55 | 30 | 40 |
| NW40-25 | 55 | 40 | 40 |
| NW50-40 | 75 | 55 | 40 |
| NW63-25 | 95 | 40 | 77.5 |
| NW63-40 | 95 | 55 | 77.5 |
| NW63-50 | 95 | 75 | 77.5 |
| NW80-40 | 114 | 55 | 77.5 |
| NW80-50 | 114 | 75 | 77.5 |
| NW80-63 | 114 | 95 | 81.0 |
| NW100-50 | 134 | 75 | 113.5 |
| NW100-63 | 134 | 95 | 117.0 |
| NW100-80 | 134 | 114 | 117.0 |
Essentially, anywhere that uses a vacuum (air extraction device) will use this fitting.
A connection fitting that smoothly bridges a large pipe and a small pipe.
