Upchurch Scientific PEEK Y Connectors are designed to split a stream or join two streams together, just like a tee. However, the configuration of a tee can lead to turbulent flow and solvent outgassing, which increases baseline noise and reduces sensitivity. The geometry of a Y connector creates much less turbulence and thus can improve analytical results.
All of our Y Connectors use 1/4-28 Flangeless Fittings, except P-515 which uses 5/16-24 fittings. The maximum recommended pressure for all Y Connectors is 1000 psi (69 bar).
To use Y Connectors in higher pressure applications, simply replace the provided fittings with Super Flangeless™ Nuts and Ferrules.
