| High Light | Agricultural Chemical Storage Vent Plug ,Industrial Chemical EPTFE Vent Plug ,EPTFE Membrane Vent Cap | ||
The D15 ePTFE membrane vent plug is a universal pressure management component for a wide spectrum of agricultural and industrial chemical storage applications. From on-farm chemical storage containers to industrial tank closures, this 15mm plug provides reliable, long-term protection against pressure-induced structural failures. Its fully encapsulated ePTFE membrane offers a broad chemical compatibility profile, handling everything from liquid fertilizers to process chemicals. Molded with a versatile HDPE housing, it can be welded or press-fit into drums, tanks, and container lids, making it a go-to choice for OEMs, chemical distributors, and storage system builders seeking a standardized, high-performance venting solution.
Long-term chemical storage presents unique challenges. Over months or years, even stable chemicals can generate trace gases, and ambient temperature cycles relentlessly pump pressures up and down. Large industrial containers and agricultural storage tanks may be located outdoors, exposed to solar heating and cold nights. Without appropriate venting, these containers can experience metal fatigue, welded seam cracking, or plastic creep rupture. Additionally, storage containers often need to be sealed against rainwater, insects, and airborne contaminants—requirements that simple open vents or bellows cannot satisfy without compromising pressure balance.
The D15 ePTFE membrane vent plug solves these long-term storage challenges with a completely passive, maintenance-free design. Once installed, it immediately begins regulating the container’s internal atmosphere. The ePTFE membrane provides a massive surface area for gas transmission relative to its size, ensuring that even large-volume containers breathe efficiently. The membrane blocks external water, dust, and microbial ingress, preserving the chemical’s quality. The plug form factor makes it easy to retrofit into existing container lids or incorporate into new designs. It supports the push toward closed-loop chemical management by preventing fugitive emissions while maintaining operator safety.

The plug operates on the principle of gas permeation through a selectively permeable membrane. The ePTFE membrane is composed of a micro-fibrillar structure with extremely high void volume. When the internal pressure of the storage container differs from ambient, gases diffuse through this structure to equalize. Liquids and solids are physically excluded due to the nanoscopic pore size and the membrane’s inherent non-stick surface. The vent plug’s rugged HDPE housing protects this delicate membrane from mechanical impact, UV radiation, and direct liquid impingement, making it suitable for exposed outdoor environments.
