Plumb Pak 1-1/2 in. Mechanical Plumbing Vent

The Plumb Pak 1-1/2 in. Mechanical Plumbing Vent is engineered to allow fresh air into drain lines while preventing unpleasant sewer gases from escaping into living spaces. Built from high-quality, corrosion-resistant plastic, this vent offers a durable and cost-effective secondary venting solution for residential and commercial plumbing systems. Ideal for sinks, islands, and fixture installations where connecting to an open vent stack is difficult, it promotes smooth gravity drainage and helps prevent plumbing trap siphoning. Its low-profile black design ensures a clean, reliable fit in tight spaces.
