Pipe Joint Testing

Straub logo

The HK Test Coupling by Straub makes it easy to conduct joint testing on straight wall concrete pipe and manholes. This external joint testing tool can maintain up to 50 psi/345 kPa of external joint pressure. The coupling provides a simplified method to ensure joints and gaskets will provide the watertight seal that infrastructure projects require.

Easy to use and install, the HK Test Coupling enables testing in the plant that simulates actual job conditions and accurately measures the resistance to external pressure. The HK Test Coupling can be reused and does not damage the concrete or require drilling holes through the bell.
