4 Cylinder OPSO Armoured Upgrade Kit
£54.95
The 4 Cylinder OPSO Armoured Upgrade Kit takes a two-cylinder Calor system up to four cylinders, so you’ve got more gas on hand and longer between changeovers. It’s part of the Calor Essentials range and comes complete with two hoses and the T pieces needed to add the extra pair of bottles.
The hoses are armoured, which gives extra protection against general wear, sharp objects and vermin, handy where cylinders sit outdoors. OPSO is the over-pressure shut-off built into this style of automatic changeover system.
A kit like this should be fitted by a competent person, following Calor’s guidance. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888 if you want to check it’s the right kit for your setup.

The 4 Cylinder OPSO Armoured Upgrade Kit is the part you need to grow a two-cylinder Calor system into a four-cylinder one. Doubling the number of bottles means more gas in reserve and longer between changeovers, which is useful on sites and properties that get through a fair amount of LPG.
It’s part of the Calor Essentials range and comes complete with two hoses and the T pieces needed to connect the extra pair of cylinders into the existing setup. The hoses are armoured, adding a protective layer that guards against general wear, sharp objects and vermin, which is worth having where bottles and pipework sit outdoors. OPSO is the over-pressure shut-off built into this style of automatic changeover system.
This is an addition to an existing changeover system rather than a complete system on its own, so it pairs with a two-cylinder automatic changeover setup. Fitting should be done by a competent person, following Calor’s own guidance.
