LACO will custom design a leak standard to one of your parts or design a reservoir to mimic it, resulting in a simulated part. We can make your simulated parts “pass” or “fail” your pre-defined criteria. This allows you to:
LACO’s high pressure leak standards allow you to calibrate high pressure systems ranging from 500 psi to 5000 psi or higher. These high pressure leak standards are critical for the following applications.
LACO has many options for connection fittings on your calibrated leak standard. These connections allow you to integrate your leak into your system for easy calibration. Connection options include:
LACO will use your specifications to create custom size and/or shape leak standards expertly engineered for your unique application.
