When do I use a one piece Uniseal versus an O-ring seal?
A. O-ring seals are most effective for operating pressures under 2,000 PSI. The Uniseal style is most effective for operating pressures above 2,000 PSI. Uniseals will operate at pressures under 2,000 PSI, but depending on their material of construction – there may be some “weepage” experienced. The higher the pressure the more effective the Uniseal becomes.
