This product is a Luer Tee fitting with a 2.5 mm pressure relief valve in the branch to provide protection from overpressurization, and a 2.5 mm check valve in the downstream branch to prevent backflow for syringe-driven systems. The check valve has a cracking pressure of 4 kPa (0.6 psid), while the pressure relief valve ranges from 100 to 300 kPa (14.5 to 43.5 psid). Both valves feature all stainless steel construction to ensure for compatibility with a wide range of fluids. The fitting is made from medical grade polypropylene.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
