Victaulic Style 75 lightweight flexible grooved coupling joins OGS grooved pipe while allowing controlled expansion, contraction and angular deflection. The offered configurations combine orange-enamel ductile-iron housings with a Grade E EPDM gasket.
Choose a flexible coupling when the system design calls for movement at the joint. The lighter housing design suits moderate-pressure piping, but the actual working limit depends on the pipe size, material and wall thickness.
Choose the joint behavior your system needs
| Feature |
Benefit |
| Flexible joint |
Allows controlled movement rather than locking the joint rigidly. |
| Lightweight housing |
Reduces coupling weight compared with heavier Style 77/177N designs. |
| Grade E gasket |
Supports compatible water-service sealing within its stated limits. |

Pressure and end-load limits are totals from all internal and external loads, based on ANSI B36.10-sized carbon-steel pipe grooved to Victaulic specifications; confirm the pipe material, wall thickness, size and complete joint design. For stainless steel, check Victaulic publications 17.01 and 17.09 rather than applying carbon-steel values directly.

Before ordering
Grade E EPDM is not compatible with petroleum or steam service. Confirm the complete gasket-service recommendation for the fluid and temperature. The coupling includes its specified gasket; adjoining pipe, fittings and system components are separate selections.
| Check |
What to confirm |
| Size and profile |
Match nominal size, actual pipe outside diameter and OGS groove dimensions. |
| Joint function |
Select rigid or flexible behavior to suit the piping design; provide the required supports. |
| Gasket identification |
Select Grade E EPDM as specified here; do not assume Grade EHP or nitrile has identical service limits. |
| Stainless-steel pipe |
Use the required Victaulic RX rolls for light-wall/thin-wall stainless pipe and verify the applicable grooving and performance data. |
| Installation safety |
Depressurize and drain the whole affected system, including isolated branches, before installation, adjustment or opening the joint. Follow Victaulic installation instructions. |
