We offer Porous Filter Plugs. These porous polyethylene vent plugs ranging from 5 to 10 micron are used for venting. These vent plugs are used in conjunction with iv lines to release venus pressure in the lines. These pressed into place in a “y” connector near the skin puncture site. These can also be pressed into an interference fit to stabilize pressure inside a container. These can also be purchased with a self sealing polymer. That swells upon contact with liquids for applications requiring rapid liquid sealing protection.
