Frequently Asked Questions
What technicians ask us most about this product
Are cylinders factory-sealed?
Yes. Stock ships factory-sealed, and pallet quantities arrive on the original pallet.
Do you sell to trade and to individuals?
Both, subject to the legal restrictions on the specific refrigerant. R-22 in particular may only be sold to technicians holding EPA Section 608 certification, which is a restriction on the refrigerant rather than on the buyer’s trade status.
Can I order a pallet quantity of something listed as a single cylinder?
Most refrigerants are listed in quarter, half and full pallet quantities alongside the single cylinder — check the category page for the refrigerant you need. If you need a quantity that is not listed, contact us.
Do you offer technical support on product selection?
Yes. If you are choosing between replacement blends or working out what a retrofit needs, our refrigerant guides cover the common decisions, and you can contact us for anything they do not answer.
Shipping and returns
Shipping is free on every order. Transit time depends on your location and the size of the order — a single cylinder ships as a parcel, while quarter, half and full pallets move by freight and take longer to arrive. Returns are free.

Ordered R-410A and it landed two days later, sealed and exactly as listed. My HVAC unit is running great and the price beat every other quote I got. New go-to supplier.

Grabbed R-404A for a walk-in cooler job. Fast shipping, tight packaging, and the cylinder was factory-sealed. Quality and price both spot on — ordering again.
