The Tuf-Tite P-45 Perforated Pipe Plug is a specialized drainage component designed to terminate pipe ends while allowing for controlled liquid release. It is primarily used with 4-inch corrugated HDPE (high-density polyethylene) piping in septic and drainage systems. 

Features:

Snap-In Design: Engineered to snap securely inside 4" corrugated pipes without requiring additional adhesives.

Controlled Drainage: Perforations allow for the gradual release of water while still capping the pipe end to prevent large debris from entering.

Durable Construction: Made from high-density polyethylene (HDPE) plastic, which resists corrosion and chemical degradation in underground or septic environments.

Standard Sizing: Features a 4.00" inside diameter and a 4.44" outside diameter with a height of approximately 1.03".

Versatile Application: Common in trench drains, distribution boxes, and general landscape drainage where complete termination is not desired.
