NVS AISI 316 Stainless Steel Butt-Weld Cap
NVS AISI 316 Stainless Steel Butt-Weld Cap
The NVS AISI 316 stainless steel butt-weld cap has butt-weld end and is available in 15 sizes from 1/2″–12″. Permanently closes the end of a welded stainless pipeline or manifold body.
AISI 316 (1.4401) is a molybdenum-alloyed stainless steel. It resists chloride media, sea water and chemicals considerably better than grade 304 and is recommended for swimming pools, coastal, chemical and outdoor applications.

Selection and installation notes
- 304 or 316? Molybdenum-alloyed; chloride media, sea water, swimming pools and chemicals. For general water and heating applications the more economical AISI 304 is sufficient.
- 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.
