Tees and Crosses

Upchurch Scientific® Tees and Crosses are available in two inert polymers and can handle pressures to 1000 psi (69 bar). Each is designed with handy mounting holes. All Tefzel® (ETFE) Tees and Crosses ship complete with 1/4-28 PFA Flangeless nuts and ETFE ferrules, while their PEEK™ polymer counterparts ship with 1/4-28 PEEK nuts and ETFE ferrules.

Our Tees and Crosses with 0.020" thru-holes (1/16" OD tubing versions) offer very low swept volumes, making them desirable for post-injector connections in low pressure systems. Larger 0.040" and 0.050" thru-hole products offer passageways for higher flow applications with minimal flow path resistance.

  • Seal off unused ports with any of our 1/4-28 flat-bottom plugs available.
  • To use the PEEK polymer versions of our Tees and Crosses in higher pressure applications, simply replace provided fittings with Super Flangeless Nuts and Ferrules.
  • High Pressure Tees, Crosses and 7-port Manifold (all with 10-32 threaded ports) available.
