These Billet High flow Y blocks are a great and cost effective way to plumb any water or coolant lines. They feature 3/4 (-12an) Hose Barb ends, not requiring you to buy multiple fittings to make your own Y Block. Simply slip your hose over the barb, and either secure with your choice of clamps, or the provided Gates Shrink clamps. They come Anodized in Black for a stealth look.
