PELCO® NW/KF Style
Vacuum Connection Parts, Fittings, Hoses and Filters

NW/KF flanges

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 PELCO® 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 PELCO® NW/KF style vacuum components are available in the standard NW16 to NW50, with some components available in the smaller NW10.

The NW/KF system refers to the internal bore in mm:
  Internal Diameter
NW10 10mm
NW16 16mm
NW25 25mm
NW40 40mm
NW50 50mm
The terms NW, KF or QF all refer to the same standard quick release vacuum couplings.
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.
