Flanged/Reducer Fitting Covers

Reducer and flanged-type 90s, 45s and Tees, are very popular fittings used where flanges or reductions take place. They are always two-piece fittings. Among the parts in this category are concentric cone reducers (CCR) which are used for straight-line reduction, and reducer end caps which can be used for flanged pipe reduction, as well as mechanical grooved reduction.
