Our 8" HDPE molded mushroom vent is available in two configurations and both include HDPE bird screen:

• Our Standalone version has an 8" size mounting flange and includes GRP hardware and a neoprene foam gasket
• Our Insert version has an 8.625" OD stub and will insert into a standard 8" PVC socket (typically a coupling or flange)

These heavy duty mushroom vents are designed to provide an intelligent, high value solution to tank venting requirements. The Standalone version includes everything necessary for installation while the Insert version is installed into an 8" socket (which is supplied by others).
