Bayliss power tube life is not infinite. Over the years, the piston moving through the seals gradually wears the seal material away, allowing a gradual seepage of wax out of the tube. This in turn reduces the pressure within the tube and eventually the opening distance achieved will be affected. This is when you need to replace the power tube cylinder.Bayliss MK7 power tubes are available with 2 different models. The only difference is the operational temperatures of the power tube. The Orchid...

This cylinder tube powers the Gigavent automatic openers with no need for electricity. It contains a mineral wax which expands with heat.
