Question by: Glen B on Jun 19, 2025, 4:52 PM
what exactly is this fitting used for? trying to figure out if it'll work for splitting a line into two directions on a hydraulic setup
Answer by: Customer Support on Jun 20, 2025, 7:52 PM
A tee adapter like this one lets you branch a single hydraulic line into two separate paths using the same connection point. All three ports on this fitting are 1/4-18 male NPT, so wherever you need to split flow or combine two lines into one, this gets that done without needing additional union fittings in between. It's a steel construction piece from Eaton Aeroquip's 2257 Series, built for pipe thread connections on both ends.

trying to split one 1/4 pipe line into two, is this the tee i need?
Answer by: Customer Support on Jul 18, 2025, 8:21 PM
For branching a line, a tee adapter is the right style of fitting. This one is a steel Eaton Aeroquip 2257 Series tee with 1/4-18 male NPT ends, so it’s meant for NPTF external pipe thread connections.
