Product Benefits

  • Used on round, arch and elliptical pipe, manholes, and box culverts with single offset joints
  • Saves money – no butyl rope, external wrap, equalization or lubrication 
  • Saves time – fast and simple installation 
  • Self-centering homing
  • Sizes up to 144” (3650 mm) diameter and virtually any size of box culvert
  • Meets all industry material requirements 
  • Standard and oil-resistant versions available 

The lubrication is contained within the rolling tube so the gasket is impervious to mud, dirt and debris. The innovative design of the gasket enables pipe and manhole sections to self-center and roll into place during the homing process to create a watertight seal.

Tylox® SuperSeal™ gaskets are available for all common configurations and can be manufactured to suit any manhole or concrete pipe size – even elliptical or arch pipe.

Pressure Rating

Pipe and manholes with Tylox® SuperSeal™ gaskets and single offset joints are regularly tested to the 13 psi/90 kPa requirements of ASTM C443 and C361. Some have been tested at higher pressures to meet more stringent jobsite conditions. Concrete box culverts with single offset joints and SuperSeal gaskets are regularly tested to 5 PSI according to ASTM C1677, but have also been tested up to 13 PSI for some joint designs. Please consult your Hamilton Kent representative regarding your application requirements.

Tylox® SuperSeal™ gaskets are produced in many different profiles to properly seal a variety of joint designs common in the pipe and manhole industries.

If your company has existing equipment for manufacturing a gasketed joint, please provide a joint drawing to your HK representative so the right gasket can be selected and priced for you. If you’re considering purchase of single offset equipment, please consult with HK so we can provide a recommended joint design for best performance and lowest gasket price.
