Black Class 150 / Schedule 40 Pipe Fittings - NPT - 200

Our class 150 pipe fittings are for Sch 40 pipe and are made of premium materials (ASTM A197 Cupola Malleable Iron, ASTM A153 Zinc Coatings) to provide maximum strength and durability while state-of-the-art casting methods ensure consistent, leak-proof fittings. The threads are carefully machined to provide easy and smooth attachment (threads are ANSI/ASME B1.20.1, class 150 & 300 malleable iron dimensions are ANSI/ASME B16.3). Standard black & galvanized steel nipples are Schedule 40 welded steel pipe material ASTM A53 Type F CW. Sch 40 are typically used in conjunction with Class 150 malleable iron pipe fittings, while Sch 80 are typically used with Class 300 malleable iron. We offer pipe nipples in a range of longer lengths, some up to 60" lengths.
