Class 150 malleable iron fittings are made with the most sophisticated metallurgical and processing controls available. Iron samples are continuously analyzed using spectroscopy to conform the material quality. This sophisticated chemical analysis is complemented by rigorous quality control of incoming raw materials and iron processing. The final casting produced by this detailed attention to quality is a close-grained, high strength, non-porous iron.

• Threads have an accurate form, thread length and straightness to allow them to easily engage threaded pipe
• Have a chamfered opening to allow faster and easier pipe engagement and also protects the fitting threads from damage during handling
• All black class 150 malleable iron fittings having outlets ranging from 1/2 IN through 4 IN are air tested at 80 PSIG
