Helium leak testing · Air pressure testing · Nashik
Helium finds it. Bubbles prove it. Your report records it.
Leak testing for industrial parts, done in-house at our Nashik facility.
01 · The part
It passes a visual check. But looks can't tell you whether it will hold gas.
02 · Up close
Too small to see. Big enough to slowly lose refrigerant, coolant or gas in service.
03 · Helium
Helium is one of the smallest atoms and reacts with nothing. If there is a path, it gets through, and the detector registers it. (Atoms not to scale.)
Services
Helium tells us whether a part leaks. The bubble test confirms it and shows where.
Test 01
The part is put under vacuum and helium gas is introduced. Helium atoms are tiny and inert, so they slip through leaks that air and water can miss. If helium gets through, the part fails. If not, it passes.
Test 02
Compressed air is pumped into the same part, for example a pipe, and the part goes into a water tub. A stream of bubbles means there is a leak, and it shows exactly where.
How it works
All testing happens in-house, at our facility in Nashik.
You send the batch to our facility. We log the quantity received.
Each piece goes under vacuum with helium on our Pfeiffer Vacuum ASM 340 leak detector. If helium gets through, the part is rejected.
Every part then gets compressed air and a water tub. Bubbles confirm a leak and show exactly where it is.
A written report for the batch: quantity received, passed and rejected.
The whole batch goes back to you with the report, usually within 1 working day.
TEST REPORT
Sample layout only. Client data is never shown.
What you get
For every batch, you know exactly how many pieces came in, how many passed and how many were rejected. No sampling, no guesswork.

Drawings and specs use different units. Type a value and see it in all of them, plus where it sits on the tightness scale.
Tip: write 1e-5 for 1 × 10⁻⁵.
"Our detector" marks the helium detection limit of our Pfeiffer Vacuum ASM 340: 5 × 10⁻¹² mbar·l/s (manufacturer spec, vacuum mode). Tightness classes are approximate rule-of-thumb values from leak-testing literature. Your drawing or customer spec always decides the pass limit.
Industries
If a part holds gas, refrigerant, coolant, oil or water, a leak test belongs in your quality plan.
Brazed copper tubes, coils and fittings that have to keep refrigerant in.
Fuel, brake and cooling lines, plus battery cooling plates for electric vehicles.
Sealed enclosures and components where moisture or gas must stay out.
Cylinders, manifolds and connectors that work under pressure.
Bodies, seats and threaded joints, checked before they reach your line.
Brazed and welded exchangers, radiators and condensers with many joints.
