For higher temperatures or immersion in chemicals, Heat Resistant Stoppers and PetroChem® Stoppers are available.
PetroChem® Stoppers are manufactured in sizes 1 – 96” (25 to 2,440 mm) and have a standard 1.3 m hose attached, each fitted with a Schrader Valve.
Similar in appearance to the standard Inflatable Stoppers, the PetroChem® Stoppers are made with an internal flexible rubber that is resistant to hydrocarbon liquids or gases.
Heat Resistant Stoppers have a temperature range up to 300ºC (572)ºF. Again, similar in appearance to the standard Inflatable Stopper, but are manufactured with Heat Covers to protect the Inflatable Stopper.
