Replacing Product Valve O-Rings
If O-rings show any signs of wear, they should
be replaced immediately. When replacing or
reinstalling O-rings onto the product valve, be
sure to use Petrol-Gel to lubricate the O-rings
as you put them on.
Figure 4: Replacing Product Valve O-Rings
Installing the Product Valve
After the product valve and O-rings have been
cleaned, add more Petrol-Gel to both O-rings
so that the product valve will have lubrication
during production. Insert the product valve
with a rotational motion to help prevent the
O-rings from catching on the ports in the
product head. If there is resistance, pull the
product valve out and try again.

Product Pistons
Each piston is attached to a piston rod and
each piston rod is attached to the strong back.
As a result, the product pistons are driven in
and out of the product head by the main air
cylinders.
