Dresser Style 80 “Ready-Pack” Split Sleeves are used to enclose and permanently repair breaks, splits and holes in cast iron pipe. Style 80 sleeves can also be used as an efficient, low-cost tapping sleeve for connecting new branch service outlets.
Style 80 sleeve bodies are cast from close-grained gray iron (malleable iron in 2” size). Steel follower rings on each end are completely enclosed in the sleeve body. When carbon steel set screws are tightened, they drawn up against the follower rings which compress the gasket creating total circumferential sealing on the pipe. Side bolts, which are fully enclosed within the sleeve body to prevent corrosion, are tightened to compress side gaskets providing a complete leak-proof pipe repair.
Style 80 sleeves are also available in a long pattern design for a larger sealing area. Style 80 repair sleeves are recommended for all customary pressures where pipe wall thickness is in conformity with specifications for standard cast iron pipe.
