Connectors utilize a swivel nut with NPS straight threads, and a cone seal. This allows the installer to thread onto NPT, NPS, BSP and most threads without tools or thread sealant. Simply thread on, and hand tighten for a zero leak seal. Small lengths of tubing can be eliminated by using stackable connectors.
