nipolet - What is a nipolet?

Nipple Olets are known as branch connection fittings used to provide an outlet from a larger pipe to a smaller one. Nipolet uses the fundamental Weldolet however the branch affixes by method for an attachment inside the olet. The bore matches the outlet bore, and the existence of a counter bore roughly the size of the OD of the outlet provides a socket where the pipe can sit, encouraging fitting and welding. The Nipolet is considered a socket fitting, and manufactured in 3000LBS, 6000LBS and 9000LBS classes.
