Thread Size

Quality USA made NPT threaded Steel weld flanges stamped from 1018 CR flat bar. Offered In sizes 1/8" NPT Through 2" NPT. Popular uses include fuel tanks, hydraulic tanks and water tanks.

NPT Fitting Sizes are based on the "PIPE" that would typically thread into these couplings. Use the Chart below to find the proper size match.

It's important to understand that both the Male and Female NPT fitting have a 1.8 DEG taper applied to the thread. This taper is intended to create an interference fit once threaded together. It is expected that the male mating fitting will not thread all the way down. Sufficient tightness is created approx 1 turn or less past hand tight, any further and you risk damaging the fitting. To get a liquid tight seal you will need to use thread sealant that is appropriate for your application

We quality check every fitting with the appropriate size L1 thread gauge before entering our inventory. We do not replace fittings after they have been welded.

Specialty Parts and Great Service

Needed a weld in 2” female bung for a fuel tank project. Google search landed me with Boyd Welding and they did not disappoint. Easy ordering, no made up minimum order extra charge BS like some other companies, and quick shipping at a reasonable rate. Thank you guys for a great experience. Will definitely be a repeat customer.
