About This Product
Insert Weldolet
Insert Weldolet is listed in the supplied source as part of the broader family of olet fittings used for branch connections in piping systems. Related products identified in the source include Weldolet, Sockolet, Threadolet, Letrolet, Elbolet, Nipolet, Sweepolet, Brazolet, Coupolet and Flangeolet.
The material range described in the source includes stainless steel grades such as F304, F304L, F316, F316L, F316Ti, F321, F347 and F904L, along with carbon steel, alloy steel, duplex, super duplex, nickel alloys, Monel, Hastelloy, Inconel, copper-nickel alloys, bronze, brass and titanium.
The source also references multiple outlet sizes, run pipe sizes, schedules, pressure classes, end connections and inspection documents. Since some of these specifications appear to be shared across different olet fitting types, the correct Insert Weldolet design, dimensions, manufacturing requirements and material specification should be verified before order confirmation.
