A 3-way Y-splitter that divides a single 1/4″ OD tubing line into two separate outlets — push-to-connect on all three ports, tool-free. For splitting a feed line to run two inline filters, two RO stages, or a fridge and filter from one source.

What it does

This Y-splitter fitting has three 1/4″ OD quick-connect ports arranged in a Y shape — one inlet, two outlets. Push tubing into each port for a secure, leak-resistant connection. It splits a single water line into two branches without cutting into the plumbing or adding a tee valve.

Common uses: feeding two inline filters from one source, branching a post-filter line to a fridge and a drinking faucet, or splitting an RO output to two dispensing points. The compact Y shape keeps the split tight for clean routing in tight spaces.

Good to know before you buy

• Cut tubing square (90°) before pushing into each port. A clean cut prevents leaks.
• Push tubing fully in until it seats. Give each tube a gentle tug to confirm.
• The fitting uses O-ring seals — no thread tape needed on any port.
• Flow splits evenly between the two outlets under normal pressure. If one branch has significantly more restriction (e.g., a clogged filter), flow will favor the other.
• Check all three connections for leaks before putting the system into service.
