PELCO^® 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 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.

	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.
