5.3.1. Tips and suggestions
Connection of pipes and fittings
Where 3/8" GAS rigid pipes or hoses are used in connections between pipes and fittings (diameter of
approximately 9.7 mm), take care to respect the pipe dimensions. Pipes of a smaller diameter do not
guarantee a pressure/vacuum seal. Pipes of a larger diameter, conversely, must be forced into their
housing and this adversely affects the installation of retaining rings (3) and (4) resulting in a poor seal.
When working on fittings that are already installed, always replace retaining rings (3) and (4) 65-AC
and 65-AA with equivalent new parts. When installing, ensure that the end of pipe (1) fully enters the
housing of fitting (5) to ensure maximum grip. If a flexible tube is used, tighten pipe collar (2)
thoroughly by hand. If a rigid pipe is used, tighten ring (2) using a wrench.
