The Gaslow Easy-Fit Rubber Hoses are available in a range of lengths. They are tested and approved with an extractability rating of 2%. However, the rubber hose leaves a plasticiser residue on regulators so stainless steel hoses are advised. Hoses fit into the inlet of every 30 mbar caravan/motorhome regulator including Gaslow changeover systems using the W20 connection. They should be changed every 4-5 years. The hoses are fitted with an easy-fit hand wheel meaning there is no need to use a spanner, making changing a bottle easy.
