Bolt Tightening for Valve Caps
Proper fastener tightening technique is essential for sealing of valve caps with soft metallic
wire gaskets used in some high pressure cylinders. It is important to draw up bolting to full
torque in even and gradual steps. Do not allow the valve cap to be tightened with bias on
one bolt or to become cocked in the bore. Such bias or cocking can cause uneven crush of
the gasket, which could cause a leak and could also cause bolt failure. This step tightening
procedure is also recommended for all valve caps.
Install the valve assembly (and high clearance spacer, when applicable), with the flat gas-
kets) and valve retainer, in the valve pocket. See “Valves - Reassembly” on page 5-33. For
