4G & 4F Profile Pipe Gaskets

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 likely 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.

1. The gasket is stretched over the spigot.
2. The gasket is equalized around the entire circumference of the spigot.
3. Bell joint is covered liberally with lubricant.
4. 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.
