Style 1200 "Flexi-Spool" rubber expansion joints are designed to handle a multitude of industrial applications. "Flexi-Spool" expansion joints are a spool-type, hand-wrapped expansion joint with several construction features that provide advantages over standard expansion joints.
The wide-arch style of "Flexi-Spool" provides several times the movement capability of standard narrow arch style joints. A high-pressure reinforcing combines both polyester fabric plies with steel wire for impressive working pressure and vacuum ratings, even at extended temperatures. A thick, wrapped-on rubber cover protects the reinforcing from damage and the environment.
Full-face duck and rubber flanges provide an optimum sealing surface. A built-on flange O-ring allows the flange to seal faster, and with less torque required. Both tube and cover can be provided in a variety of materials in order to handle conditions involving chemicals, moderate temperature extremes, abrasion, or other conditions. Materials include Neoprene, Chlorobutyl, natural rubber, Nitrile, Hypalon, and are also available with white PTFE liners.
