NVS AISI 304 Stainless Steel Hex Nipple
NVS AISI 304 Stainless Steel Hex Nipple
The NVS AISI 304 stainless steel hex nipple has bSP male thread on both ends, hexagon wrench flats in the middle and is available in 12 sizes from 1/8″–4″. Connects two female-threaded parts (valves, sockets, elbows, tees) directly; the hexagon body makes tightening with a wrench easy.
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.
- Joining stainless steel directly to galvanized or carbon steel pipe can cause galvanic corrosion; a dielectric (insulating) union is recommended between different metals.
