Tylox® SORT Gasket

Profile gaskets for O-Ring Joints on Concrete Pipe and Manholes

Enhanced Performance... Ease of Installation!

Designed to replace O-ring gaskets for watertight sealing of confined-groove joints, the Tylox® SORT Series offers considerable benefits in ease of installation.

Benefits of SORT Series of gaskets

  •  The SORT gasket shape provides lateral stability during homing process. Gasket will not “roll” out of groove causing bell breakage and/or mis-alignment and leakage. The gaskets shape also prevents the possibility of gasket twist, eliminating the potential for bell “roll-back” and potential leakage. For these reasons, SORT gaskets are ideal for use in jacking applications.
  •  Reduced installation time and effort due to reduction in homing force provided by the profile gasket shape. Reduced homing force means less “stretch” on the gasket, which means less effort involved in installing and equalizing.
  •  Reduced installation time due to elimination of requirement for lubricating of spigot groove and full gasket area prior to installation. Gasket need only have the upper surface lubricated, after insertion in the groove.
  •  Profile gasket design provides more sealing area, in low deformation situations (applied side-loads) and also offers enhanced sealing capabilities around bug-holes and defects in the spigot/bell sealing area, when compared to a traditional O-ring.

Materials and Identification

Tylox® SORT gaskets are manufactured from a variety of synthetic rubber compounds, to meet the material requirements of ASTM C361, ASTM C443, ASTM C1619, California Greenbook and CSA A257.

The applicable specification(s) and useage mode for a particular gasket are identified by a colored stripe around the periphery of the gasket:

  • Standard
  •  C443, A257, C1619 White Stripe
  •  C361, A257, C1619 Blue Stripe
  •  California Greenbook Green Stripe
  • Oil-Resistant*
  •  C361, C443, A257, C1619 Orange Stripe
  •  California Greenbook Yellow Stripe

* Note that the additional physical properties required to achieve Oil Resistance have a significant impact on availability, handling and cost. Please refer to the pdf file “Oil Resistant Gaskets” in the “Tech Notes” section of the website’s "Resources".

The above listing covers the standard, North American, specifications. Gaskets materials are available to meet many other specifications. Please consult your Hamilton Kent representative regarding materials to meet your particular specifications.

Pressure Rating

Tylox® SORT gaskets are suitable for use in systems with up to 13 PSIG (30 ft Head or 90kPa) pressure requirements.

Higher head pressures may be possible with a custom design. Please consult your Hamilton Kent representative regarding your specific requirements.


Tylox® SORT gaskets are not WHIMIS listed.

Tylox® SORT gaskets are made from cross-linked, polymeric rubber, which is not considered a health hazard. As with any rubber product, the gasket may smolder or burn when exposed to a naked flame. Fire-fighters should wear self-contained, positive-pressure, or pressure-demand, breathing apparatus; and utilize water-spray, air-foam, dry chemical or CO2 type extinguishing media.

Storage and Handling

Proper care of the gaskets prior to installation will ensure maximum ease of installation and maximum sealing properties of the gasket.

All rubber gaskets are required to be stored in a sheltered, cool, dry place at the precaster’s facility, as well as on the job site.

Gaskets must not be stored near any electrical equipment that produces ozone. They must be protected from prolonged exposure to sunlight, extreme heat in the summer, and extreme cold, snow and ice in the winter.

All gaskets must be protected from harmful substance such as dirt, mud, dust and grit.

All gaskets, other than oil-resistant gaskets, must be protected from contact with solvents and petroleum based greases and oils.
