Gas Cap Vents

Manufacturers use POREX® Gas Cap Vents in gasoline tank caps for lawn and garden equipment such as line trimmers or chain saws. Our vents offer consistent vent rates and equalization of a gas tank’s pressure during use and prevent gasoline from escaping the container. They are oleophobic and highly resistant to chemicals and abrasion. In addition, POREX Gas Cap Vents may be directly welded either thermally or ultra-sonically to a range of plastic cap materials.
