NW/KF Flange Adapters to Male NPT Thread

Used to connect pipes and systems with NPT thread to NW/KF flange system. Stainless steel adaptors are welded and helium leak tested. Aluminum adaptors are made from one piece (more cost effective alternative). Use OC® Three as a sealant and to prevent seizing. Please note that NPT (National Pipe Thread) does not refer to the outside diameter of the thread. Please see the NPT Table at the end of this page for size and specifications.
