TH Marine Y piece 1-1/8" Black HDPE

Barbed Y-Fitting, 3 Way, 1⅛” Hose, Black

T-H Marine barbed Y fittings are molded specifically to fit marine hose dimensions.
A fitting with three openings, a Y fitting is used to create branch lines. It is a type of tee fitting which has the side inlet pipe entering at a 45° angle, or an angle other than 90 degrees. 
Y fittings are similar to tees except that the branch line is angled to reduce friction and turbulence that could hamper the flow. In boat applications, a Y fitting can be advantageous because it can allow better drainage and may be easier to install due to space limitations.
T-H Marine’s Y fittings all have the same barb dimension for each leg.
