Leak tightness tester – LTT

The SCITEQ Leak Tightness Tester seamlessly performs all steps of the test required by the EN1277 standard. The LTT is one of the markets most durable and robust solutions for testing joints of buried plastic pipe systems.

The standard solution is available in three test frames available for following pipe dimensions as standard:

  • Ø90 – 315mm
  • Ø110 – 630mm
  • Ø630 – 1600mm

The LTT can be customized for other pipe dimension range. Please contact us for info.

Product highlights

  • Robust construction
  • High accuracy
  • Suitable for up to Ø1600 mm pipes or larger on request
  • Data logging
  • Floating pipe during testing
  • Extremely durable design


The leak tightness tester performs test of the tightness of elastomeric sealing ring joints for buried thermoplastics non-pressure piping systems. The rigid and robust construction of the SCITEQ leak tightness tester ensures reliable test results of up to Ø1600 mm plastic pipes – even larger pipe dimensions on request.

Automatic and extremely durable

The testing principle comprises exposing the test pipe to a vacuum (internal negative air pressure) for a specific period, filling the test pipe with water and subsequently exposing the pipe to an internal hydrostatic pressure for a specific period. During testing, the joint will be subjected to deflection. The automatic deflection system and floating beams ensures a 100% correct diametric- and angular deflection of the pipe. The automatic water supply system also includes a bleed function that maintains pressure below maximum test pressure while the sample is filled. Furthermore, the built-in drainage system means that you easily and quickly can repeat tests.

Each stage of the test is monitored in order to establish a possible joint leakage.

The SCITEQ Leak Tightness tester enables you to test according to the standard EN1277.
