Metric Urethane Rod U-Seal, 32.00 mm ID, 40.00 mm OD, 6.00 mm Height

Those dimensions line up exactly with what this seal is built for. The 32mm ID rides on the rod, the 40mm OD fits the housing bore, and the 6mm height covers the groove depth. As long as your groove is cut to metric spec for a U-cup profile, you're looking at a direct fit.

The key dimensions are 32 mm ID, 40 mm OD, and 6 mm height. That means it is sized for a 32 mm rod in a metric rod sealing setup, with the seal’s outside diameter at 40 mm and an overall height of 6 mm.
