DISCOVER OUR O-RINGS GUIDE
O-rings are a key component of how our valves work. They provide an internal seal to keep the valve's poppet in place, as well as move forward off of the poppet’s cartridge seat to allow regulated flow through the valve. For optimal seals in your low flow, low pressure check valves, Smart Products USA offers 7+ o-ring materials. Click below to learn more about each material.
