Smith-Blair 441 OMNI Couplings are a sensible way to reduce your stocking requirements while increasing your
capability to join a wide variety of types and sizes of pipe.
441 Bolted Straight and Transition Couplings fit pipe O.D. sizes within specified range extremes. All practical range variations can be accommodated with a selection of interchangeable color coded follower flanges and gaskets.
These ductile iron sleeves combined with a small inventory of color coded follower flanges and gaskets will permit coupling various types of pipe with O.D. differences up to 2.4" in some cases.
