K614
K614 is a rod buffer seal. It provides the designer with a compact low friction seal for light to medium duty hydraulic cylinders.
This compact rod/gland seal provides optimum sealing performance combined with smooth operation and low levels of breakout and dynamic friction.
It is designed to provide a action valve to prevent excessive pressure build up in the cavity between buffer seals and the rod seal. It used to act as a buffer seal for the primary rod sea. K614 profile provides the majority of the rod sealing performance while allowing fluid to the by pass and energize the primary rod seal. Fluid located between The K614 profileand rod seal will relieve back into the cylinder by flowing past.
