When it comes to ensuring watertight connections in critical infrastructure, the HK Test Coupling by Straub delivers consistent, repeatable results. Acting as a dependable pipe coupling tester, this tool allows engineers and contractors to quickly verify the performance of pipe joints before installation. Designed for use on straight wall concrete pipes and manholes, the HK Test Coupling helps confirm that gaskets and joints will stand up to real-world conditions.
Testing pipe joints during the manufacturing process saves time and prevents costly rework in the field. With the HK Test Coupling, you can simulate real conditions, applying up to 50 psi / 345 kPa of external joint pressure. This pipe joint tester is reusable, easy to install, and requires no drilling or damage to the bell or spigot. It’s a practical solution for maintaining the high standards of modern infrastructure projects.
Designed with engineers and contractors in mind, the HK Test Coupling offers several important benefits that make pipe joint testing faster, safer, and more reliable:
