These injection-molded adapters make connections to female 1/8" and 1/4" National Pipe Thread (NPT) ports.
Molded from PEEK™ polymer, Upchurch Scientific® NPT Adapters are durable and chemically resistant. We provide a variety of female (internal) threads, as well as a male (external) threaded version, suitable for most low pressure fittings on the market today.
All of our NPT adapters have a 0.062" (1.60 mm) thru-hole, except U-504 and U-514 which have 0.125" (3.18 mm) thru-holes. All included fittings are for 1/8" OD tubing, except U-504 and U-514, which come with fittings for 3/16" OD tubing.
Our U-500 and U-510 NPT Adapters are great for attaching 1/8" OD fluoropolymer sparging lines to sparging gas tank regulating valves. Simply thread the appropriately-sized NPT Adapter into the valve's receiving port and then attach your sparging tubing to the adapter body using the fittings provided.
