4G & 4F Profile Pipe Gaskets

Our 4G & 4F profile pipe gaskets meet or exceed:

  • ASTM C1619 Standard Specification for Elastomeric Seals for Joining Concrete Structures
  • ASTM C443 Standard Specification for Joints for Concrete Pipe and Manholes, Using Rubber Gaskets
  • CSA A257.3 Gaskets for Concrete Pipe

Type 4G and 4F profile gaskets are designed to seal single offset joints in manholes, concrete and other types of pipe. 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.

Features and Benefits

  • Rubber compounds were developed specifically for concrete pipe sealing
  • Each profile design has been analyzed and optimized for a specific joint configuration
  • Automated processing equipment eliminates variability in sizing
  • Extrusion process is laser-controlled for precise, consistent sizing>

How They Work

  • Wedge design reduces homing force while it concentrates sealing force.
  • Gasket slope creates an entrance angle that helps center the pipe during installation.
  • Unique “Swayback” design reduces push back during pipe installation.
  • Increased rubber mass provides more gasket contact area between gasket and pipe.
  • Less likely to roll, pinch, or break bells.
  • Installation is simple and easy.

Applications

  • Sanitary Concrete Pipe Joints
  • Stormwater Concrete Pipe Joints
  • Manhole Joints
  • Box Culvert Joints
  • Elliptical Concrete Pipe Joints
