    The rubber gaskets that are used to seal the clear cylinder to the end bulkheads are not making a perfect seal as they seem to have been distorted. Does anyone know where you can get new ones or a replacement for them that would do the same job?

    They're o-rings. Most likely Nitrile rubber(also sold as Buna-n), but you can use silicone rubber o-rings too.

    The manual states the o-ring diameter (this is usually the internal diameter of the o-ring), but not the cross sectional thickness- probably 3 or 4mm. Also not sure on rubber hardness, most nitrile o-rings tend to be 70 Shore A hardness, but they can vary from 55-80 shore A. Silicone o-rings tend to be around 50-60 shore A, so a little softer.

    O-rings are readily available from seal suppliers, ebay etc.
