Stainless Steel Lock Nut - 1" NPS
For a better hold, use lock nuts as they have a little more thread. This 1" NPS lock nut is made from 304 Stainless Steel for corrosion resistance and durability.
|Features:||An NPS fitting has straight threads and an NPT fitting has tapered threads. Straight pipe threads need an o-ring to create a proper seal. NPS and NPT fittings may look like they fit together but they are unable to create a proper seal together. For best results combine NPS fittings together.|
