NPT stands for National Pipe Thread. NPT threads are widely used for plumbing and industrial piping systems because they provide a secure, leak-proof connection. Our 163/65 fittings, like the 65-163 model, are made with care and attention to detail, featuring reduced parting lines and smoother edges for better fluid flow. The low-temperature galvanizing process results in a more durable coating, ensuring a longer-lasting fitting. Additionally, all fittings are 100% pressure tested to 300# class, providing peace of mind for reliability and safety.
