Product Description

Pipe penetration seal is a reusable, permanent, water-tight rubber seal.

The MetraSeal Pipe Wall Penetration Seal quickly creates a mechanical water-tight seal, filling the space around any round pipe including: concrete, steel, plastic, cast iron, copper, and electrical conduit to name a few. The modular seal design creates a permanent hydrostatic seal rated at 20 psig (40 feet of head), sealing out ground water while absorbing noise and dampening vibration.

The MetraSeal mechanical-type seal assembly installs up to 75% faster than standard cured seals, resisting aging, water, oil, ozone and sunlight for up to 25 years. Available in multiple elastomer/hardware materials, the MetraSeal can fit any application. By providing electrical insulation to the pipe joint, it protects against pipe corrosion, protecting your investment.

  • Install around any round pipe
  • Available in multiple rubber materials to fit any application
  • Faster installations
  • Install in all weather conditions
  • Use in subgrade, exterior or interior applications
  • To quickly calculate the right seal for your application use our online seal calculator.
  • For Off-Center applications visit our Off-Center Seal page.
