The TUF-TITE s-40 is a 4-inch blue pipe seal designed to create a watertight connection where a pipe passes through a septic tank riser, distribution box, or similar buried structure. The seal fits both 4-inch Schedule 40 PVC pipe and 4-inch corrugated pipe, making it a versatile option for residential and light commercial drainage and septic installations. Plumbers and septic system installers use this component to prevent groundwater infiltration and effluent leakage at pipe penetrations. The blue color coding helps differentiate it from other seal sizes or types on the job site.
This seal is used in below-grade septic system installations, drain field piping, and drainage applications where a reliable, flexible pipe-to-structure connection is required. It is appropriate for new construction and retrofit work involving 4-inch Schedule 40 or 4-inch corrugated pipe runs entering risers, tanks, or catch structures. Licensed plumbers and septic system installers are the primary users of this component.
Compatible with 4-inch Schedule 40 PVC pipe and 4-inch corrugated pipe at septic tank risers and similar drainage structures.
Installation is typically performed by a licensed plumber or certified septic system installer in accordance with local plumbing and on-site sewage codes. Ensure the pipe end and the receiving opening are clean and free of debris before seating the seal. Follow the manufacturer's instructions for proper seating depth and orientation to achieve a watertight fit.
