The 4G and 4F gaskets are designed to be self centering and require less homing force during pipe joining than an o-ring. They are less like;y to roll, pinch or break bells. Press-Seal can provide sealing deformation curves and we offer gasket design assistance. With the accurate profile dimensions and designs for a complete line of standard and specially designed concrete joint configurations.

How It Works

  • The gasket is stretched over the spigot.
  • The gasket is equalized around the entire circumference of the spigot.
  • Bell joint is covered liberally with lubricant.
  • Bell and spigot are homed creating a watertight seal.

Why It's Better

  • Optimized profile designs for a wide variety of joint configurations.
  • Accurate profile designs covering a variety of applications.
  • Wide range of compounds that can be applied in multiple applications.
  • Simple installation methods.

Basic joint preparation and installation of Press-Seal’s 4G profile gaskets on pipes and manholes.
