We have recently reorganized our PVC Unions page. They are now much easier to find.
Imported WHITE & GRAY unions These are unrated unions in both white and gray color and slip x slip and thread x thread configuration. They fit sch 40 and 80 pipe, but are unrated and un-certified. Cannot be used on any project that requires NSF or IAPMO certified products. VERY LOW PRICE. Quality very good for imported (Chinese) parts.
Sch 80 Unions WHITE These are NSF and IAPMO rated fittings and very high quality. NSF Rated for potable water. WHITE in color, but still sch 80 unions.
Sch 80 Unions GRAY. These are NSF and IAPMO rated fittings and very high quality. NSF Rated for potable water. GRAY in color.
Specialty Sch 40, Misc & Odd Unions These are mostly used for swimming pools, spas, irrigation, fish, etc. Good quality unions, but some are not rated and their pressure ratings will be lower than the sch 40, sch 80 unions. Some have NSF ratings, some don't.
Union Parts This is mostly tail pieces, end pieces, split nuts, o-rings, gaskets, washers, etc. It's all for unrated unions, all the rated unions are not available by pieces.
