A setting tool 10 for performing a wellbore operation includes a mandrel 20, a cylinder 30 slidably engaged with the mandrel, and a variable volume first chamber 60 formed between the mandrel and the cylinder and a containment member having a second chamber 70 adjacent to the first chamber. The setting tool also includes a support fluid disposed in the first chamber, a slidable support 80 axially and circumferentially distributed inside the first chamber, and a valve 50 disposed between the first chamber and the second chamber. The valve is configured to flow the support fluid from the first chamber to the second chamber. The support fluid and the slidable support support the cylinder against a downhole pressure.
