Inner Tube Testers
Matrix Inner Tube Testers are designed to quickly and accurately detect leaks in RC drill rods and inner tube assemblies. Built similarly to a thread protector with a vent hole, the tester threads directly into the pin end of the RC drill rod to create a simple and effective testing setup.
To perform the test, compressed air is introduced through the opposite end of the drill rod. If air escapes through the vent hole in the tester lid, it indicates a leak within the inner tube or sealing system.
In many cases, replacing worn or damaged O-rings will resolve the issue and restore proper sealing. If the leak persists after O-ring replacement, it is likely that the inner tube has ruptured, meaning the inner tube must be replaced or removed from service.
Matrix Inner Tube Testers provide a fast, reliable way to diagnose RC drill rod inner tube leaks, helping drilling crews maintain proper sample recovery and minimize downtime.
