What We Do

We design, build, and service leak test instruments for production environments. Our systems handle mass flow testing, pressure decay, and differential pressure methods.

Whether you need a standalone instrument or a fully integrated test station, we can configure a system for your application.

Leak Test Instruments

Production-ready instruments for mass flow, pressure decay, and differential pressure testing. Configurable for your specific parts and tolerances.

Integrated Systems

Turnkey test stations with fixturing, PLC controls, and data collection. Designed to drop into your production line.

Calibration & Service

Field service, calibration, and preventive maintenance to keep your equipment running accurately. We service what we sell.

Technical Consulting

Application engineering support for new programs, test method development, and troubleshooting existing systems.

Industries We Work With

Our equipment is used in production facilities across several industries where leak testing is a critical quality requirement. Most of our work is in automotive, but we also support aerospace, medical device, HVAC, and general industrial manufacturing.

If you are testing parts for leaks on a production line, chances are we have worked on a similar application.

Common applications include:

  • Engine blocks, cylinder heads, and transmission housings
  • Fuel system components and fuel rails
  • HVAC/R heat exchangers and refrigerant circuits
  • Medical device housings and sealed assemblies
  • Aerospace fluid system components
  • Electronic enclosures requiring IP-rated sealing
