O-ring seals – in perfect shape, part 3

Production of the O-ring groove

In addition to the correct selection of O-ring seals, the correct introduction of the O-ring groove is essential for the optimum sealing result. In the third part of our series ‘O-ring seals – in perfect shape’ we show you how you can save time during production with our countersink for O-ring seals, and increase the quality of the O-ring groove at the same time.

Comparison: Production of the O-ring groove with a milling cutter or countersink for O-rings

A direct comparison shows that considerable time is saved when the groove is introduced using a countersink for O-rings. Furthermore, the difference in quality is clearly seen in the following figure. When produced with a milling cutter, milling grooves are created which run at the bottom across the groove. This is not optimal for sealing. With our countersink for O-rings, on the other hand, concentric grooves are visible which make optimal sealing possible. This saves time and provides security.
