B-407-PP Collar Mount
Collar Mount SingleWall Tank Sump
The “PP” collar mount variant of the B-407 REVOLUTION Series Tank Sumps is designed for installation to the short round tank collars typically installed by the tank manufacturer. The 2-piece 407-PP sump features a high-neck round reducer at the top and is Octagonal (8-sided) all the way to the round collar mount interface at the bottom. The bottom half of the sump features a deep tongue-in-groove channel for sealing via a simple slurry pour. Read more
The lower seal to the tank collar must be made by a fiberglass lamination. This sump is kitted to include a complete slurry and lamination kit and all the tools and supplies needed to complete the installation. It features a vertical o-ring seal at the top reducer edge which is easily serviceable. This o-ring mates with our new submersible water-tight SNAP-LOCK cover. Paired with any of our bonded all-fiberglass entry fittings, you will never have to worry about water intrusion or the risk of contaminating the local environment.
