Y Fittings - Wye Fittings

SKU: Y-118-DP


  • Molded specifically to fit marine hose dimensions
  • Allows better drainage than tee
  • Compact install

A fitting with three openings, a wye 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. A standard wye is a "Y" shaped fitting which allows one pipe to be joined to another at a 45 degree angle. Wyes 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.

Our Y fittings all have the same barb dimension for each leg.

Perfect to tie 2 Bilge pumps into 1 Thru-Hull

Installed 2 Bilge pumps (Attwood 1100) in my tunnel hull and wanted to tie both into one 1-1/8” hose connected to a single thru-hull.
Worked and fit as described. You will need hose clamps.

Great service

Purchased several different items and their service is outstanding. I made a mistake with measuring and no questions asked handled the exchange immediately. A pleasure to deal with.

These were designed for 1-1/2 in hose however they don’t fit they are about 1/8 to small for the hose.
