Tests only the weld. Localized testing lowers fluid use and significantly reduces maintenance project timelines.
Enables welds to be subjected to pressures up to 4,500 psi, providing confidence in performance and long-term reliability.
Our tools make it possible to achieve significant reduction in wastewater - just 1/4 gallon of water required for a 24" test
Works in any orientation. Covers multiple pipe schedules and diameters with one tool - even in elbows and tees.
Tool insertion and positioning
Hydratight places the in-line tool around the weld or section to be tested or isolated.
Seal engagement
Twin seals create a secure, vapor-tight barrier or define a localized test area.
Localized pressure testing
The isolated section is pressurized to verify weld integrity without affecting the rest of the system.
Results verification
Technicians confirm that welds meet safety, performance, and compliance standards.
Safe maintenance support
The barrier allows hot work or modifications to proceed with minimal risk.
Tool removal and reuse
After testing, the tool is removed and ready for future deployment.
