NW/KF Style Vacuum Connection Parts, Fittings, Hoses and Filters
The NW/KF style, quick release vacuum connections are the industry standard for vacuum components in the low and medium vacuum range and can be found on a variety of laboratory, production and test equipment. All NW/KF style vacuum connections conform to the international ISO 2861/I standard. Many pumps and vacuum gauges use the standard NW/KF flanges for easy integration. Test systems can be readily and quickly built utilizing the large selection of NW/KF type components and can be easily modified for new tasks and applications. The NW/KF style vacuum components are available in the standard NW16 to NW50, with some components available in the smaller NW10.
Most standard components are made from a high quality grade 304 stainless steel. Stainless steel is a cleaner, stronger and more durable alternative to aluminum. For specific applications, some vacuum components are also available in aluminum. The competitively priced PELCO® Ball Valves offer an elegant, easy and quick way to close/open vacuum lines.
