The Type 4G & 4F profile gaskets were developed to specifically meet the needs of contemporary concrete pipe joint designs.
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.
Basic joint preparation and installation of Press-Seal’s 4G profile gaskets on pipes and manholes.
