NSF stands for National Sanitation Foundation. If a fitting or pipe is NSF rated it just means it has passed some standard or test procedure and is certified for use in a residential or commercial plumbing project. The problem is there are many different NSF standards and they have different applications. On our site what we try to do is let people know when a fitting is NOT NSF rated. Most of the fittings we sell are NSF rated, (including those we import from China) however, not all.
