Installation Hole Requirements
The Lee Check Valve, 6 mm Zero Leak, Press-In product is designed for installation into plastic manifolds or fittings and to perform well under adverse conditions. Installation hole specifications, as found on Lee Installation Hole Drawing1INST129591S (Appendix A), will ensure proper operation of the Lee Check Valve, 6 mm Zero Leak, Press-In product. The hole should be clean, dry, and free of burrs/flash. The series of smoothly curved lands of the Lee Check Valve, 6 mm Zero Leak, Press-In product allow the valve to be pressed in while the plastic flows into the adjacent grooves. Some plastics with sufficient elongation, such as Polypropylene, Nylon, Acetal, Polyethylene and PEEK, cold flow into the grooves affecting retention and sealing. Rigid plastics, such as acrylic and polycarbonate, have the risk of cracking from the stress of the interference installation. For installation into these types of plastics contact your local Lee Company Sales Representative for more information.
