5. If unit functions properly in the previous step, close cylinder valve

and note the readings of both the inlet and delivery pressure

gauges. After 5–10 minutes, a drop in reading of either gauge indi-

cates a leak in the system.

Use an approved oil-free leak detection fluid to locate possible

leaks at the inlet, any threaded port, through the regulator di-

aphragm, or through the outlet valve. PTFE tape is an accept-

able pipe thread sealant. If other sealing materials are pre-

ferred, those materials must be compatible with the gas that is

being used in the system.

6. If leak is at the inlet or at a threaded port, relieve all pressure from

the regulator and then tighten. if leak continues or is found at the

diaphragm and outlet valve, remove regulator from service and

have it repaired or replaced.

B. Storage

1. Regulators taken out of service for extended periods should re-

ceive proper care to extend their service life.

2. Regulators used in a non-corrosive gas service should be wiped

clean with a clean, dry, lint-free cloth and sealed in a plastic bag for

storage in a dry area at room temperature.

3. Regulators used in a corrosive gas service should be well flushed

with dry nitrogen and sealed in a plastic bag. Regulators used for

corrosive service may continue to corrode in storage after exposed

to atmospheric oxygen and moisture.

C. Repair Service

Any regulator in need of service should be returned to your equipment

supplier for evaluation.
