Poly II High Pressure Pipe Seal

SKU
prod-81
Use the POLY II for the inlet & outlet pipes on septic tanks, aerobic systems, or anywhere you need water tightness. This new hybrid seal will mount to our existing mandrel that bolts directly to the septic tank form just like the original. The Poly II will meet the vacuum & hydro-static pressure requirements of A.S.T.M. spec. C-923 for 2", 3" and 4" SCHD. 40. It will allow you the water-tightness that is now required and the flexibility of choosing what size pipe you want!
  • Accepts 2", 3" and 4" Schd. 40 and corrugated pipes
  • Prevents infiltration and exfiltration
  • No grouting for secure pipe connection
  • Fits tank walls 2 1/2" - 6"
  • Free mandrels with initial order
    Polylok Pipe Installation:
  1. Mandrel is cut to 1/8" less than the wall thickness of the septic tank. Mandrel is then attached with a single 3/8" carriage bolt
  2. Polylok snaps onto the mandrel and is held securely by two friction fit" positioning posts. Form is then closed and is ready to pour and strip
  3. Once on the job site, just tear out the size you need and slide your pipe into the seal
  4. Pipe is then inserted into the seal. No leaks. No grout. It's that simple
    Directions:
  1. Remove the correct size tear-out on the seal (TEAR OUT- DO NOT CUT OUT)
  2. Chamfer the OD of the pipe, removing all burrs, sharp or jagged edges
  3. Apply a minimal amount of grease to the chamfered edge of the pipe
  4. Slide the pipe into the seal
  5. Remember to always backfill properly around and underneath the pipe
