GROOVED
Grooved seals are bi-directional seals that are specially designed to deal with a wide range of sealing pressures. This seal type features two different pressure sensitive energizers, and it is capable of handling a wide range of pressures, while still maintaining a good level of sealability. The four-lobed ring at the top is the low pressure energizer of the PTFE seal. At higher pressures this four-lobed ring is not as effective, and instead the O-Ring below is the energizer for the PTFE cap. As an added bonus, the center groove on the PTFE piston ring cap acts as a reservoir for lubrication during operation.
