    Long Rubber Couplings in Pool Plumbing

    I have some long rubber couplings (1-2 feet) in my pool plumbing, allowing some flex near the pump and filter. They are connecting 1-1/2" pipes together. I want a piece of this for another project, but I can't find anything as to where to get this. Lowe's and HD have short (4") couplers, and I can't find anything online or in pool stores. Does anyone know where I can find this, or even what a primary use is for it so I can narrow my search?

    Thanks

    Perhaps it is some sort of radiator hose like used on cars? Picture would help.

    I thought of the radiator hose, but it's perfectly straight, as opposed to the usually molded shapes of radiator hoses. It's just like the one in the link, except much longer:

    You can get radiator type hose that is not pre molded. A picture of the actual piece would be better. I know there is no such thing made by fernco nor none of its competitors, as I use those type of fittings quite often.

    I thought radiator hose are not very good at UV protection. Overtime, they become brittle when exposed to sunlight. The coupling hose that are used for solar panels are actually gas line hose that can be special order from an automotive store. Last - have you considered using flexible PVC (Spa Flex)? I don't know the UV protection on Spa Flex, but they use standard schedule 40 fittings.
