Y-fitting with 2 pcs internal thread and 1 pcs exterior in funky matt black finish. The Y-fitting is with universal 1/4" BSPP (G1/4)
thread, so you can choose the fittings you want to use !
A Y-adapter is brilliant in situations where you want to run a portion of your system in parallel to reduce the restriction on the main loop. It may be cooling modules for less heat components like RAM or in situations where you have to use a small inner diameter on the tubing.
