Single stage or two stage regulator?
| Type | How it works | Best for |
|---|---|---|
| Single stage | Drops cylinder pressure in one step. Outlet pressure rises a little as the cylinder empties. | Welding, cutting, balloons, general use |
| Two stage | Drops pressure in two steps, so the outlet stays steady from full to empty. | IVF incubators, labs, analysers, medical use |
| Flowmeter | Shows flow in litres per minute instead of pressure. | TIG and MIG welding, oxygen for patients |
Regulators by gas
CO₂ regulators
For soda machines, beverage plants and incubators. Busy plants may need a CO₂ heater to stop freezing. CO₂ cylinders
Oxygen regulators
Flowmeter regulators for patients, single stage for cutting. Always kept oil free. Oxygen cylinders
Argon regulators
Flowmeter regulators for TIG and MIG welding. Argon cylinders
Nitrogen regulators
High outlet regulators for pressure testing, two stage for labs. Nitrogen cylinders
Helium regulators
With a balloon filler for decorators, or for leak testing and labs. Helium cylinders
Hydrogen regulators
Two stage regulators made for hydrogen, for lab use. Hydrogen cylinders
Looking after your regulator
- Open the cylinder valve slowly, standing to the side of the gauges.
- Keep oxygen regulators free of oil and grease.
- Check connections with soapy water after fitting.
- Do not use a regulator with a cracked gauge or a damaged thread.
- Use each regulator only with the gas it is made for. Never move an oxygen or hydrogen regulator to another gas.
Frequently asked questions
Can I use an oxygen regulator on another gas?
No. Fittings differ from gas to gas, and oxygen regulators are kept oil free for safety. Use a regulator made for your gas.
Single stage or two stage?
Single stage suits welding, cutting and most everyday use. Two stage suits labs, IVF incubators and anything that needs a steady flow as the cylinder empties.
Do you fit the regulator for me?
Yes. Bring your cylinder or tell us the gas and we fit and check the right regulator.
