Tylox® Dual Seal II Series Connector

Cast-in, push-fit connectors for concrete structures. Superior performance by design.

The unique funnel-shaped sleeve design, and the high-tear resistance custom rubber compound, work together to offer superior flexibility under pipe deflection; while the high hoop forces, generated by the exclusive pressure-ring design, maintain water-tight sealing around the connecting pipe O.D.



The enhanced performance of the double-ring water stop couples with the increased embedment length of the cast-in flange to provide superior sealing capabilities at the concrete/rubber interface.

The custom designed formulation of the EPDM compound used to manufacture the Dual Seal II offers improved resistance to ultra-violet and ozone degradation from exposure to sun-light when the concretes structure is stored for extended periods. Optionally, the sleeve is available in Nitrile rubber, for use in applications requiring oil-resistance.


Materials and Identification

Tylox™ Dual Seal II connectors are manufactured from synthetic rubber compounds, to meet the material requirements of ASTM C923.

Connectors are available for “Standard” or “Oil-resistant” applications. Oil-resistant connectors will have an orange dot on the rubber molding.

Other materials and specifications may be available as custom order. Please consult your Hamilton Kent representative regarding your specific requirement.

Pressure Rating

Tylox® Dual Seal II connectors are designed for water-tight connections to meet the requirements of ASTM C923 - 13 psig water-tight sealing in straight alignment and 10 psig water-tight sealing at 7° axial deflection.


Tylox® Dual Seal II connectors are not WHIMIS listed.

Tylox® Dual Seal II connectors are made from crosslinked, polymeric rubber, which is not considered a health hazard. As with any rubber product, the connector 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 connector prior to installation will ensure maximum ease of installation and maximum sealing properties of the connector.

Connectors must not be stored near any electrical equipment that produces ozone.

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

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