Polyurethane seals and O-ring wear and effects

O-rings are often confused with urethane seals, which look similar but function differently.



The main difference between the two is their longevity and functionality. The o-ring is part of the dynamic rod seal, so the o-ring can move with the installed components like a gasketless faucet. The sealing element is installed as part of the static rod seal, so once pressed, the sealing element does not move.



Because O-rings move, they are subject to friction and wear from movement. As a result, they wear out and must be replaced. The assembly with the o-ring installed is designed to be taken apart so that the o-ring can be replaced. The frequency of replacement depends on the application, material, degree of movement and use.



In contrast, since the sealing elements in a pressure fitting are static, they function in the press, but do not move during system operation. Therefore, they do not suffer from the same wear and tear and do not have to be replaced. Once compressed, they are secured to extend their mounting position.









Collectively, the effect of seal manufacturers on industrial society has been to eliminate rubber seal ring manufacturers and drastically reduce the time long associated with rubber o rings manufacturers.
