Edwards Vacuum components

NW fittings, otherwise known as ISO-KF, are the industry standard for many applications in the low to high vacuum range. They are ideal for achieving dependable cost effective performance down to 10-7 mbar across a range of applications for the light to harsh duty. A simple fastening method means that systems can be easily assembled and a leak tight vacuum seal is quickly achieved. They are manufactured to ISO 2861 and SIN 28403 standards with nominal diameters from 10 mm to 50 mm.
