Silicone/Elastomeric valves, seals, and other flow control products.

Flow Control Valves:

LMS has developed proprietary technology to manufacture elastomeric valves using the liquid injection molding (LIM) process. Known as the Duckbill Killer, we’ve patented a revolutionary valve design that has applications in a wide variety of markets with performance characteristics far superior to common valves in the market place, including duckbill valves. These bidirectional and one-way silicone valves open and close at predetermined forces and vacuums and are used to dispense liquids, gases, and powders.

LMS branded valve solutions:

SureSnap® Valves
SureFlo® Valve Fitments
MediFlo® Valves for Medical Device Applications


Whether it’s a connect/disconnect application in Foodservice, or an access procedure in Medical Device, LMS has developed elastomeric-based seal assemblies that keep fluids and gases in their place. LMS seal assemblies effectively eliminate ball and springs, providing a more simple connection and reduce the number of moving parts. These seal designs also self close, proving your application with improved performance and less leaking.
