TOPFLEX Series TT
(Twin-sphere Connectors with flanges)

Topflex Series TT (Twin-Sphere Connectors with flange) is ideal in heating and air conditioning systems where low initial cost and maximum reliability are a must. The TT Connectors are Twin-Sphere joint with EPDM cover and EPDM tube. It provides excellent resistance to ozone and sunlight aging and oxidation. The unit has an EPEM tube, which is good for hot and cold-water service and chemicals. The Twin-spherical design not only provides a high pressure rating, also provide greater flexability, thus protecting mating flanges, especially PVC and fiberglass types. The steel flanges easily rotate on the bellows which makes it easier to line up the bolt holes during installation when mating flanges are out of line. Separate retaining rings are never required. Flanges are of zinc-plated steel with a steel bead (flange retainer). Standard sizes range from 1½" through 12" I.D., with operating pressures at 228psi at -20ºC~100ºC., and 14"I.D. through 20" with operating pressures at 114 psi at -20ºC~100ºC.
