The outstanding service record for DuPont Kalrez V-rings parts in oil production applications is best shown by
the results of testing V-rings recovered after six years’ service in a producing well. As shown in Table 1
and Figures 1–3, except for slight drop in hardness, the aged V-rings were indistinguishable in physical
properties and appearance from the un-aged control.
We know of no other product that performs as well in service conditions this severe.
