# 6" to Dual 4" Y-Splitter

D-Central Technologies design. Release 2026-08-19. SKU `y_split_6_to_2x4`.

A wye that takes one 6-inch trunk into 2 branches of 4 inch. The branches leave the trunk at an angle, so the split is made by turning the stream rather than stopping it against a flat wall.

## What it fits

This part interfaces with the fan and duct pattern its geometry is cut for, named on the product page. Compatibility is that interface and nothing wider - a family name is not a blanket claim. Read the Fits row on the product page against your exact machine.

Hydro and immersion machines have no fan face. No part in this line fits them.
