Concentric & Eccentric Reducers

Concentric Reducers Expansion joints installed in piping systems must be anchored on both sides of the joints to avoid the use of control rods. If control rods are installed as a safety measure, the locking nuts must be backed off with a clearance equal to the specified axial movement. The expansion joint will exert thrust…

Duct Type Expansion Joints

Duct Type Expansion Joints Flexible Connectors are used in DUCT SYSTEMS to reduce Vibration Transmission and Shock, and Accommodate Thermal Movements at minimum stress to the ductwork. In Seismic zones they accommodate differential motion across building expansion joints as well. BULLETINS & DOCUMENTATIONHAVE A SPECIFIC QUESTION?RELATED PRODUCTS

Mercer Expansion Joints

Mercer Expansion Joints The Mercer Rubber Company was started in 1865 as a small factory on Mercer Street in Hamilton Square, New Jersey. The company specialized in molded rubber mechanical products, rubber sheeting and conveyor belting, and began building rubber expansion joints in the early 1930’s. Mercer was completely owned by one family from its…

VIBRAFLEX

VIBRAFLEX The Vibraflex 150 reinforced rubber pipe is hand built by our skilled craftsmen. To minimize pipe elongation, the carcass is constructed of multiple plies of high tensile polyester tire cord or Kevlar for high temperatures. Helical spring steel wire is imbedded in the carcass to prevent kinking or crushing as well as for radial…

MASONFLEX

MASONFLEX In 1976 we introduced our first spherical expansion joints, under the name “MASONFLEX”. Although we had higher burst pressures than the other manufacturers, our technical literature still made people aware that Nylon reinforcement had to be derated at higher temperatures. MASONFLEX connectors did not always require control rod protection as the lengths at given…

SAFEFLEX

SAFEFLEX EXPANSION JOINTS Safeflex expansion joints are molded and vulcanized in hydraulic presses. This high pressure process produces a smooth finished product with outstanding adhesion between the cover, reinforcement and tube. Most of our competitors still use Natural Rubber impregnated Nylon tire cord between sulfur cured, EPDM covers and tubes. This construction becomes brittle with…

Rails

Rails & Bases Type RND rails are structural steel channels furnished with double deflection neoprene mountings bolted to the web. All metal mounting parts are neoprene covered to avoid corrosion and provide a bottom friction surface. They need not be bolted to the floor but bolt holes are provided for those areas where bolting down…
