KF-40 to 1.25" NPT Male Vacuum Fitting | LoCo Science

Connect to a 1.25” NPT-Female adapter with this KF-40 to 1.25” NPT-Male adapter. Commonly used in the assembly of frontline vacuum plumbing and process systems, the KF-40 to 1.25” NPT-Male adapter creates a tight connection with other KF-40 flanges and 1.25” NPT-Female adapters. Made from high-grade stainless steel, the adapter is heat-resistant and will stand up to corrosion from chemicals. The quick flange allows for easy assembly with all NW/KF-40 flanges that meet ISO-KF standards. Used with a KF-40 circumferential clamp and centering ring, the two flanges will be secured with a lock-tight, leak free seal.
