4G & 4F Profile Pipe Gaskets

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.

• 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.

• 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.

• 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
