About Frostline

Frostline designs, fills, brands and sells a five-product refrigerant collection in the United Kingdom: R32, R410A, R134a, R1234yf and oxygen-free nitrogen for HVACR work. We are the manufacturer and the brand of record for every item on this website. This is not a marketplace, and we do not resell other companies' goods.

Each cylinder carries the Frostline name on the product itself — stamped into a steel plate on the shoulder — and on its paperwork. If you cannot see our mark on the vessel, it is not ours.

The catalogue is intentionally short. We sell only the five products listed in the shop. We do not publish unverified customer counts or star ratings. We do not claim compatibility with other manufacturers' equipment by name.

HFC refrigerants are sold to F-gas qualified engineers only. Checkout collects a certificate number. Frostline trades from 6 Simonburn Ave, Newcastle upon Tyne, NE4 9UA, United Kingdom. You can reach us on 07347 949616 or trade@frostline.co.uk. See Contact for the same details used across this site, checkout and structured data.
