Leak-Tight, Safe & Quick Connections


Reduce Time to Run Leak Tests

Minimize the set up time it takes to prepare the engine for a leak test. Compared to using in-house solutions like clamps and pad seals, FasTest Connection Tools can drastically improve throughput. Reducing set up by a couple minutes can increase the total throughput of engines per shift.


Reduce False Failures

False failures are a costly result typically caused by poor connections and seals. By using accurate sealing Connection Tools, leak tests are more reliable and consistent - if a leak test fails, the leak is not from the point of connection.


Improve Quality of Test

Improve Quality of Test by replicating the real-world connections on the engines. This gives operators a better representation of the engine's performance once installed in the vehicle. Many in-house solutions can mask leaks instead of identifying them.
