KF-50 to 1.25" NPT Female Vacuum Fitting | LoCo Science

Each KF-50 to 1.25” NPT-Female adapter meets ISO-KF standards to fit with all NW/KF-50 fittings and flanges. It features a quick flange design for convenient and easy assembly and disassembly. Most commonly used in the construction of frontline vacuum plumbing and process systems, the KF-50 to 1.25” NPT-Female adapter is made of stainless steel and is resistant to heat and corrosion. The NPT-Female adapter will thread onto most 1.25” NPT-Male adapters for a leak-free seal. A circumferential clamp and centering ring create a stronger bond between the KF-50 flanges.
