Leak Testing Machine Manufacturers
Icon Engineers is a leak testing machine manufacturer based in Noida, serving Indian industries since 2005. We design and build air leak, water leak and pressure decay testing machines, along with the fixtures and couplers that go with them, all made in-house. Our machines are used by automotive, HVAC, pipe and valve manufacturers to catch leaking parts before they reach the customer.
Our Leak Testing Machines
Every component is different, so we build machines around your part, not the other way round. Our range includes:
Water Leak Testing Machine
For components that must be checked under water, where leaks show up as bubbles. Suitable for radiators, tanks, castings and similar parts. View details →
Digital Leak Testing Machine
A digital pressure decay tester that gives a clear pass/fail result with set test pressure and test time, so the result does not depend on the operator’s judgement. View details →
Radiator Leak Testing Machine
Built for radiators and heat exchangers, with fixtures designed to seal the inlet and outlet ports quickly. View details →
Hose Pipe Leak Testing Machine
For testing hose assemblies and pipes at the required pressure, using leak testing couplers matched to your pipe ends. View details →
Fuel Pipe Leak Testing Machine
For fuel lines and similar automotive pipe assemblies, where a leak is a safety issue. View details →

Which Leak Testing Method Should You Use?
| Method | How it works | Best suited for | |
|---|---|---|---|
| Pressure decay | The part is filled with air to a set pressure, sealed, and the pressure drop is measured over time | Rigid parts such as castings, pipes, valves, tanks | |
| Vacuum decay | A vacuum is created and any pressure rise is measured | Sealed packs, flexible and medical parts | |
| Water-bath (bubble) test | The pressurised part is submerged and bubbles show the leak point | Radiators, tanks, parts where you need to see where the leak is | |
| Differential pressure | The part is compared against a known good reference part | Applications needing higher sensitivity and faster cycles |

How Much Does a Leak Testing Machine Cost in India?
The price depends on your requirement, mainly on these factors:
- Test method and required leak sensitivity
- Component size and test pressure
- Number of test stations
- Level of automation (manual, semi-automatic, PLC-based)
- Fixture and coupler complexity
- Data logging and traceability options
Frequently Asked Questions
It depends on the test method, pressure range, number of stations, automation level and fixture requirements. Share your component details and we will send a quotation.
Pressure decay measures the drop in pressure inside a sealed part and gives a pass/fail result without needing water. Water-bath testing submerges the pressurised part and shows exactly where the leak is through bubbles. Pressure decay suits production-line testing, while water-bath is useful when you need to locate the leak.
Start with your component, its test pressure, the smallest leak that matters, and your production rate.
Yes. We make custom fixtures and couplers, and build the machine around your part.
Automotive, HVAC and refrigeration, pipes and valves, packaging, medical device and general engineering industries use leak testing to avoid field failures and warranty claims.
It checks the integrity of vials, blister packs and containers so that sterility and shelf life are not compromised. Vacuum decay and pressure decay are common methods.
