Always keep oil and grease away from the torch, oxygen cylinders, valves, regulators, hoses, and
fittings. Oxygen reacts explosively when mixed with oil or grease.
Never clean any internal part of the oxygen system. Never use compressed air, oil, solvents, or any
other material to clean the oxygen system. The oxygen system could become contaminated and
cause internal burning in the torch or hose. All service on oxygen delivery parts must be performed
by a qualified and knowledgeable technician.
Always ensure the cylinder to be used is marked with a sticker showing a valid inspection
certification. High pressure gas cylinders are required to comply with current inspection and testing
requirements. Cylinders must undergo internal visual inspection annually and pass hydrostatic
testing every three years (composite) or five years (all metal).
Never use a cylinder that appears damaged. Always have a licensed test facility inspect
questionable cylinders.
Always open the oxygen cylinder valve slowly. Do not allow rapid pressurization of regulators,
hoses or cylinders. Failure may occur, injuring the operator or bystanders.
Always check the manufacturer’s working pressure of the cylinder to be filled, and the stamped
safety device on the cylinder valve to ensure the cylinder will not be overfilled.

Transfill procedures
:
1) Ensure that the transfill hose, adapters, cylinder valves, tools and any other items to be used
are clean and free from oil, grease or other contaminants.
2) Lay both cylinders on the ground (so they can’t fall) and position them so as to allow the
transfill hose to reach between them without putting a strain on the hose or any connections. If
one cylinder must be upright (e.g. filling from a six-pack) support the other cylinder in such a
manner that it can not fall and does not strain the transfill hose or any connections.
3) Purge both oxygen cylinder valves to remove debris by quickly opening then closing the
oxygen cylinder valves.
4) Check to ensure the transfill hose inlet stem seats (either Teflon tip or o-ring style) are present
and in good condition.
5) Connect the transfill hose to the source cylinder by threading one end of the hose on to the
oxygen valve outlet fitting. Note that the transfill hose inlet is fitted with a hand-tight nut and
Teflon tipped inlet nipple. A complete seal can be achieved by hand tightening.
6) Purge the transfill hose assembly to remove debris by quickly opening then closing the oxygen
cylinder valve.
7) Attach the cylinder to be filled (target cylinder) to the other side of the transfill hose.
