Action Can LD-90 Gas Leak Detector

Action Can LD-90 is a professional-grade water-based gas leak detector engineered to safely identify leaks in pipework, valves, and fittings on all gas types. The non-flammable, solvent-free formulation forms highly visible bubbles at leak locations, revealing even non-visible leaks on low-pressure systems. Conforming to BS EN 14291:2004 and MIL-L-25567 standards, LD-90 serves gas fitting, plumbing, heating, HVAC, and automotive air-conditioning applications.

Key Features

  • Instant Bubble Formation — Forms highly visible bubbles precisely at leak locations, providing immediate visual confirmation of gas or air escape.
  • Low-Pressure System Detection — Effective on low-pressure systems where many detectors fail, identifying leaks that would otherwise remain hidden.
  • Oxygen System Compatible — Formulated to MIL-L-25567 standards for safe use on oxygen systems and other specialised gases without introducing contamination.
  • Non-Flammable Water-Based Chemistry — Water-based formulation eliminates flammability hazards, safe for use on live gas systems and around ignition sources.
  • Solvent, Silicone, and Oil-Free — Absence of solvents, silicones, and oils prevents contamination of gas systems or subsequent coating processes.

Description

Gas System Leak Detection Challenges

Gas leaks represent serious safety hazards—undetected leaks create flammability risks, oxygen depletion concerns, and system inefficiency. Visual inspection alone is inadequate; many leaks are non-visible even when present. Traditional leak detection methods require expensive equipment, extended downtime, or invasive system modifications. LD-90 addresses these challenges through chemistry that creates immediate visible confirmation of leaks through simple spray application.

Bubble Formation Chemistry for Leak Identification

LD-90's water-based formulation creates a surfactant solution that forms stable bubbles when exposed to escaping gas or air. The bubbles persist long enough for visual inspection, but deflate immediately upon gas cessation, eliminating false positives. This bubble mechanism is far more reliable than dye detection or electronic sniffers, providing visual proof rather than interpretation.

Low-Pressure System Capability

Many commercial leak detectors fail on low-pressure systems—insufficient pressure creates no visible reaction. LD-90's formulation is specifically optimised for low-pressure detection, identifying leaks on systems operating at pressures below 1 bar where conventional products would fail. This low-pressure capability extends leak detection to HVAC systems, air lines, and low-pressure hydraulic assemblies.

Oxygen System Compatibility and Safety

Oxygen systems present unique challenges—contamination risk and flammability concerns eliminate many cleaning and detection products. LD-90's MIL-L-25567 compliance ensures oxygen-system safety. The formulation introduces no contamination risk; residues are simply water that evaporates or can be rinsed away. This oxygen compatibility expands leak detection capability to aircraft, medical, and industrial oxygen systems.

Non-Flammable Application Safety

Traditional solvent-based leak detectors present flammability hazards near ignition sources, pilot lights, or spark-prone environments. LD-90's non-flammable water-based formulation eliminates this hazard, allowing safe application in any environment—around welding operations, pilot lights, or heated systems. This safety profile is essential for heating engineers and gas fitters working on operational systems.

Economical Multi-Application Versatility

Beyond gas leak detection, LD-90 serves multiple applications—air line inspection, water system verification, industrial pressurised system testing. This versatility eliminates the need for specialty detectors for each gas type or application. A single product serves diverse leak detection needs across industrial, automotive, HVAC, and plumbing applications.

More Information

Application Instructions

Ensure electrical equipment is turned off before testing. De-energise control systems and ignition sources to eliminate sparks or ignition hazards.

Verify the gas system is pressurised and functional. The system must be under pressure for leak detection—atmospheric or depressurised systems show no leaks.

Identify areas requiring leak inspection. Plan testing to cover critical junctions, valves, regulators, joints, and connection points.

Shake the LD-90 container well before use. Mix thoroughly to ensure uniform liquid consistency.

Select appropriate application method. Use TwinSpray for ergonomic application or standard aerosol based on convenience and access requirements.

Spray LD-90 evenly over the area to be tested. Apply a light, continuous mist across the entire surface area under inspection.

Observe for bubble formation indicating leaks. Bubbles will appear immediately at any leak location where gas or air escapes.

Mark leak locations for documentation. Identify and note all leak locations observed; photograph for records if required.

Verify leak location by bubble cessation. Once spray application ceases, bubbles will deflate if no gas escape is occurring—confirming genuine leak identification.

Repeat testing on additional areas. Systematically test all connections, valves, and potential leak points in the system.

For oxygen systems, wash with water after testing. On oxygen equipment, rinse away LD-90 residue with water to prevent any residue accumulation.

Document findings for maintenance records. Record leak locations, severity, and areas inspected for system maintenance and compliance documentation.

FAQs

How quickly does LD-90 form bubbles after detection of a leak, and how long do bubbles persist?

Bubbles form almost immediately upon LD-90 contact with escaping gas or air—typically within 1–3 seconds. Bubble persistence depends on leak size and gas pressure; larger leaks produce more vigorous bubbling that persists throughout gas escape. Once gas cessation occurs, bubbles deflate immediately, providing clear confirmation that the detected location is a genuine leak rather than a false positive from residual moisture.

Can LD-90 be used on all types of gases, including oxygen systems and specialty gases?

Yes. LD-90 is specifically formulated for compatibility with all gas types including oxygen, nitrogen, argon, and other specialised gases. The MIL-L-25567 compliance ensures oxygen-system safety. However, on oxygen systems, rinse away residue with water after testing to prevent any residue accumulation. For other gas types, no special precautions are required beyond standard safety protocols.

Does LD-90 require special equipment or training to use, or can any technician apply it?

LD-90 requires no special equipment or training—spray application is straightforward. Simply shake the container and spray the area under inspection. Anyone with basic understanding of the system being tested can apply LD-90. However, interpretation of results and appropriate action on detected leaks should be performed by qualified technicians familiar with the system design and safety requirements.

Will LD-90 leave residue that could contaminate the gas system or interfere with future testing?

LD-90 is water-based with zero contamination risk to gas systems. The water residue either evaporates naturally or can be rinsed away with water if residue is a concern. On oxygen systems specifically, water rinse-off is recommended to prevent residue accumulation. For non-oxygen systems, no residue concern exists; LD-90 leaves no chemical contamination or film that would interfere with future testing or system operation.
