Product Announcement from Main Manufacturing, Inc.
SAE flanges are manufactured in accordance with the mounting dimensions and O-rings of SAE J518 specifications, either code 61 or Code 62, and ISO 6162. Stock flanges include socket weld, butt weld, NPTF, and SAE straight thread connections and are available as reducers, in-line, elbows, tees and wyes.
Companion (flat-faced) flanges, for unions or converting split flange connections to pipe or tubing, are available with either inch or metric tread. The stated pressures are from the SAE J518 and are not derived by Main. Connections are no stronger than the weakest link (including welds, fasteners, and fittings, especially larger straight threads).
