The gas cylinders were used inside containers to get helicopters out to oil rigs. The client could not find anybody else who could do it for them.
We had it moulded in Thailand, and the client needed about 2,000 lengths of it, each 1-metre 50mm long. The stock product was 1 metre long and they wanted the extra 50 millimetres attached to it.
New tooling was made to make the rubber longer and this is now the exclusive property of Spectrum Rubber.
