7705 Standard Flexible Coupling


– Angle-Pad Design –

The Shurjoint Model Z05 is an angle-pad design rigid coupling for moderate pressure piping services including fire mains, long straight runs and valve connections.  The angle-pad design allows the coupling housings to slide along the bolt pads when tightened.  The result is an offset clamping action which provides a rigid joint which resists so called ‘snaking’ of a long straight run.  Support and hanging requirements correspond to ANSI B31.1, B31.9 and NFPA 13. With the removal of only one bolt you can make a fast and easy “swing-over” installation.

The Shurjoint Model Z05 is available with a standard “C”shaped or GapSeal gasket type to meet your specific service requirements.





The Model 7705 Standard Flexible Coupling is a standard flexible coupling for use in a variety of general piping applications of moderate pressure services.  The model 7705 couplings features flexibility that can deal with misalignment, distortion, thermal stress, vibration and noise and also resist seismic tremors.  With the use of Model 7705 couplings you can even design a curved layout.  See Typical Applications – Flexible Couplings on Shurjoint cut sheet #B-19.


All Model 7705 couplings are comprised of two identical ductile iron housings segments, EPDM rubber gasket and plated track bolts & nuts.  Housings segments are supplied with our standard painted finishes, i.e. orange or RAL3000 red.  Optional finishes such as hot dipped zinc galvanized and custom epoxy coatings are available.
