Sea Tech's Quick Connect Fitting. Elbow - Union x Male Pipe - 1/2" NPT. 15mm metric series.

Rated to 250psi at 75?F and 100psi at 140?F. O-ring guide properly aligns O-ring seal and prevents O-ring damage and dislodging during installation. Maximized flow rates since fittings connect on the outside of the tubing. Fittings can rotate while under pressure without scoring. Components can be disconnected and reused without tools by simply pushing in on the (lockable) collet. SeaTech female swivel connectors utilize a nut with NPS straight threads and a cone seal; this allows the installer to thread onto NPT, NPS, BSP and most 1/2" male threads without tools.
