NVS AISI 304 Stainless Steel Weld Nipple (Single-Threaded)
NVS AISI 304 Stainless Steel Weld Nipple (Single-Threaded)
The NVS AISI 304 stainless steel weld nipple has bSP male thread on one end, plain end for welding and is available in 12 sizes from 1/8″–4″. Used to change from a welded stainless pipeline to a threaded connection: the plain end is welded to the pipe and a valve or fitting is screwed onto the threaded end.
AISI 304 (1.4301) is a general-purpose chromium-nickel stainless steel, widely used for drinking and domestic water, hot water, heating and cooling circuits, compressed air and food plants.
Threads are BSP (Whitworth); do not combine with NPT-threaded parts.

Selection and installation notes
- 304 or 316? General purpose; water, heating and cooling, compressed air and food plants. For chloride-containing media, sea water or swimming pools choose AISI 316.
- Seal threaded joints with PTFE tape or a stainless-compatible liquid sealant; over-tightening stainless threads can cause galling.
- For welded joints use stainless pipe of the same grade and a suitable filler wire; clean the surface after welding (pickling / passivation).
- Joining stainless steel directly to galvanized or carbon steel pipe can cause galvanic corrosion; a dielectric (insulating) union is recommended between different metals.
