MDC MODEL 101-C “CABLESPHERE” MOLDED (SPHERICAL) TYPE RUBBER EXPANSION JOINTS
MDC Model 101-C “Cablesphere” is the ultimate rubber expansion joint / flexible connector. It has all the benefits of standard Model 101 with the added feature of pre-assembled control units. The concern as to whether the system is anchored and/or guided is eliminated efficiently and cost effectively. The 101-C “Cablesphere” requires no field labour; control units can’t be forgotten or mis-installed.
The standard “Cablesphere” body is constructed of multiple layers of Neoprene* and bias-ply tire cord reinforcing. The spherical shape allows pressure to be exerted uniformly in all directions making an extremely strong joint. The cables are galvanized aircraft cable permanently affixed to the flanges. The cables are designed for the maximum test pressure of the joint. No adjustment can, or need be made to the cables. They are sized to prevent the joint from extending past its limit.
Please note: the elongation of the “Cablesphere” is purposely restricted compared to the Model 101. This is done to accommodate the 90% of the applications where Model 101-C “Cablesphere” is installed as a pump connector and elongation is not desired.

Solid plate steel flanges grip the sealing area and provide a fluid tight connection. All flanges are drilled mate with 150# companion flanges. The arch is self-cleaning, thus eliminating the need for filled arch when solids are present in the stream.
* Other standard materials: EPDM, Nitrile (Buna-N), Hypalon, Viton. Available as Twin Sphere – “Double Cablesphere”.
