Keyed OMEGA® quick couplings are specifically designed for
small flexible hose and plastic tubing applications which require
positive mechanical connections and non-interchangeable
lines. They provide economical, keyed, high reliability,
fool proof connections that are compatible with lower pressure
and size requirements for instrumentation applications.
Warning: Standard thermoplastic and chrome-plated
brass quick disconnects cannot be interchanged with keyed
quick disconnect couplings because they will leak.
