This upgrade kit converts a 2-cylinder LPG changeover system into a 4-cylinder setup, giving a larger propane supply with fewer cylinder changes. It's suitable for both manual and automatic changeover regulators and includes everything needed to add the extra cylinder connections to an existing system.
The kit contains two 35" pigtails with a non-return valve and excess flow valve fitted, along with two W20 changeover tee pieces to connect the additional cylinders into the regulator manifold. Both pigtails are built to EN 16436-1 Class 3 and approved by Calor Gas for use with propane, rated to 30 bar working pressure with a 90 bar burst pressure.
Each hose is finished in black with an orange identification stripe and carries a self-adhesive safety label, and the whole kit comes with a 5-year warranty. It suits static caravans, park homes and off-grid properties needing extended gas supply, as well as catering units and mobile food trailers running higher-demand LPG systems.
This kit provides everything needed to add two extra cylinders to an existing 2-cylinder changeover system, without having to source pigtails and tee pieces separately. Non-return and excess flow protection is built into the pigtails, and both hoses and tee pieces are Calor Gas approved and built to EN 16436-1 Class 3. For static caravans, park homes or catering setups that need a bigger propane reserve with fewer cylinder changes, it's a straightforward way to extend capacity while keeping the same safety standard as the rest of the system.
