Calibrated Leak Standards

Calibrated leak standards for calibrating and verifying helium mass spectrometer leak detectors and all types of leak testing systems. Leak standards incorporate proprietary microtube glass capillary technology for repeatable and reliable performance. Available in a wide range of flow rates, configurations, and tracer gases, including helium, hydrogen, air, argon, and many other gases.

NIST-traceable calibration services backed by A2LA-accredited calibration lab (ISO 17025:2017, ANSI/NCSL Z540-1-1994) and an ISO 9001:2015 certified quality system.

Custom Leak Standards

Simulated Part Leak Standards

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:

  • Test your part on various leak test systems
  • Validate your testing procedures
  • Increase confidence in your testing capabilities

High Pressure Leak Standards

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.

  • Fuel Injectors
  • Aerospace
  • Oil and gas pipelines
  • Hydraulic systems
  • High-pressure vessels

Custom Connection Fittings

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:

  • NW flanges (16, 25, or 40)
  • NPT (1/8” or 1/4” male or female)
  • Staubli 1/8” quick disconnect
  • Straight thread (M8 male or 10-32 male)
  • Swagelok (1/4”)
  • Sniffer adapter
  • Any custom or unique fitting requested

Custom Size Leak Standards

LACO will use your specifications to create custom size and/or shape leak standards expertly engineered for your unique application.
