Even thought our cylinders are very reliable, occasionally they do require a new seal kit to be installed.
This can be done in one of two ways:
1) You can send back the cylinder to Multicyl for a complete refurbishing, or
2) You can purchase a seal kit and do the repair yourself.
The thought of disassembling a cylinder can seem daunting to some people, however, we have made some handy PDF files with pictures detailing how to change the seals in your Multicyl
MC series, XL series, and DX series manuals can all be found here: Multicyl Resource Page
And as usual, if you have any questions, feel free to contact one of our friendly and knowledgeable staff members
