A seal for around a pipe penetrating through a wall. A rubbery reducer boot includes a flexible material-reservoir defined by a material curved-fold allowing a pipe-engaging tubular portion of the boot to be moved outward and inward from a relaxed position, and to be angled in extension relative to a stationary back portion of the boot. An end of the pipe-engaging tubular portion includes areas allowing the application of a hose clamp about the tubular portion to compress against the exterior of a secondary containment pipe adjacent the terminal end of the pipe, and the application of another hose clamp outward beyond the terminal end of the secondary pipe and clamping of the boot about a further-extending primary pipe. The back end of the boot near the material-reservoir includes an annular groove for receiving an annular first end of a tubular fitting assembly. A third and larger hose clamp is positioned about the back of the boot to compress and secure the boot sealed about the tubular fitting assembly. An opposite end of the tubular fitting assembly includes a laterally extending flange for abutting a wall with the annular first end of the tubular fitting assembly passing through a hole in the wall. A seal is provided between the tubular fitting assembly flanged end and the wall, and the boot provides a seal between the tubular fitting assembly first end and the pipe passing through the entrance seal and wall.
