  • Meets the material requirements of ASTM C923
  • Provides watertight connections of at least 5 psig

Designed to replace mortared joints between connecting PVC pipes and a concrete pipe, manhole or structure, Tylox® HKT connectors save you construction time and money. Eliminating mortaring saves time in the field, reduces costly joint maintenance and cleanouts, and protects the environment. Unlike rigid, mortared joints, HKT concrete pipe to pvc adapter are flexible. Our superior rubber compound makes a flexible rubber connection that minimizes joint leakage when settlement occurs.

Available in two models, the compression-fit HKT series is today’s answer for watertight, efficient and environmentally conscious stormwater conveyance applications.

Engineered to accommodate differential settlement, the flexible, rubber construction of Tylox® HKT connectors allow for watertight connections of at least 5 psig in straight alignment.
Tylox® HKT connectors are manufactured from synthetic rubber compounds to meet the material requirements of ASTM C923. They 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 a custom order.

The HKT is available in sizes for 4” (100 mm) to 15” (375 mm) PVC connecting pipes.
