Type 4G and 4F Profile Gaskets For Single Step Joints

Single step joints make concrete pipe and manhole production easier and more profitable, and the 4G and 4F profile gaskets make sealing of single step joints for concrete pipe and manholes reliable and economical. Press-Seal Gasket offers the Type 4G and 4F profiles in a wide variety of sizes and compounds for virtually any single step application. These gaskets represent years of successful use under the most demanding conditions. Our engineering department can easily determine which 4G or 4F is right for your sanitary, storm or manhole needs. We offer complete joint design service for those producers interested in converting equipment to the single step design. Type 4g and 4F profile gaskets conform fully to ASTM C 443 and to ASTM C 1613.

Easier Installation

  • Less homing force required due to wedge-shaped design
  • Self-centering during jointing, more easily aligned
  • Swayback compression relief prevents joint "pushback" effect
  • Easier to lubricate, install, and equalize on pipe
  • Less likely to roll, pinch, or break bells of pipe

Superior Design and Performance

  • More gasket surface contact area against pipe joint surfaces
  • Single-step pipe joint easier to produce than confined o-ring
  • Larger cross-section allows for greater tolerance variations
