KKA3S-02M Applications
The KKA3S-02M is the socket half of SMC's KKA stainless steel S-coupler series, mating with a KKA plug for quick connection of water and air lines. Its SUS304 body and FKM seal handle corrosive or washdown environments, and the non-greased build avoids fluid contamination. The built-in check valve stops flow on disconnection to limit spillage, while the ball-free, spring-free construction keeps the flow path open and the body compact. The male Rc 1/4 thread installs directly into ports and manifolds.
