The Allegheny 40585B is a 3-inch steel short radius belled tee. It is designed for tank trailers, but has many applications across piping systems. It features belled ends that provide better piping alignment, and since it's a welded-style fitting it offers faster installation compared to traditional butt-welded fittings. Constructed from 16-gauge steel with a 3-inch short radius, the 40585B offers durable performance for creating branch connections in tank trailer piping systems requiring steel construction.
