Series 450 Flexmore Expansion Joint

Mercer Flexmore Series 450 is the most economical, full-pressure elastomeric expansion joint available. Tough fabric and tirecord plies are bonded between the tube and cover in a steel mould and then cured in a thermostatically controlled steam chamber.

The product is uniform in both appearance and performance. A wide, low profile arch provides exceptional flexibility and virtually eliminates the need for filled arches in all but the most severe sludge and slurry applications. External integral flange reinforcing rings control both radial and arch swell. A variety of cover and tube elastomers are available, offering superior chemical, aging and temperature resistance from 30° (-1°C) to +250°F (121°C) operating temperatures. Such materials as EPDM, Hypalon, Neoprene, Nitrile and more.

They are available in single (1) arch constructions, up to 6 arch types to give capability for additional allowable movement. Carcasses are made of multiple plies of tough, rubber impregnated fabric and tire cord, with optional coating of Hypalon paint available. The retaining rings are rigid, baked enamel ductile iron. Other materials or finishes can be produced on special orders. Pipe sizes from 1-1/2” up to 36” are available. Control rods can be supplied if required. All Mercer type connectors are made by hand to meet the specifications of the application.
