Halkey Roberts Pro 1F 33g CO2 Zinc Coated Cylinder with V86140 bayonet attachment specific to the Halkey Roberts Pro 1F Inflator.
These Halkey Roberts Pro 1F 33g CO2 cylinders are manufactured to the highest standards. 33g refers to the quantity of CO2. The Gross Weight of the cylinder is stamped on the bottle. 139.0g is the weight of my current batch and that should be consistent.
When weighing this type of cylinder you should allow for the additional V86140 bayonet fitting which is 2.5 grams. So in the above example where the cylinder is stamped with 139.0 grams, the Pro 1F version should not be less than 141.5 grams.
NB. Items containing CO2 cylinders can be shipped anywhere in the UK although express shipping is not possible to some destinations. RTS can also supply CO2 items to most European destinations using overland transport. Please check my carriage info page for more detail.
Cylinders should not be used if they are showing signs of deterioration. Such signs could be rust, or scarring of the end cap.
The user also has to check the plastic bayonet attachment with the Pro 1 F Cylinder to make sure it is intact.
If you are unsure if the cylinder is full you can weigh it on calibrated scales to check. If in doubt, don’t use.
NB. The bayonet is factory fitted and glued. It is not possible to buy the parts separately.
