#034 Jet Swet 3/4" Replacement GasketAll Gaskets on the Jet Swet tools are a silicone composite for extraordinary heat resistance and are completely replaceable. Jet Swet tools hold more pressure than any other tool in its class because each gasket is designed, formed and manufactured specifically for Jet Swet tool and pipe for which it is designated. For this reason, and for the superb performance customers are used to in the Jet Swet line of tools, Jet Swet gaskets are not interchangeable and the tools should not be modified to accept any other size or brand of gasket.
