Insert the HP (high pressure) packing (1, fig. 132). Given the slight interference between the seal and the
liner, to avoid causing damage, we recommend using the special tool (part #F27540100 for SK20, SK22 and
SK24 and part #F2750900 for SK226, SK28 and SK30) (1, fig. 133).
The HP seal must be inserted into the liner as shown in fig. 132 and 134.
Before inserting the HP seals, they must be lubricated with silicone grease (type
OKS1110). following the instructions below:
The external diameter must be only lightly lubricated.
On the internal diameter the grease must be applied taking particular care to
fill all the indentations between the seal lips, as shown in fig. 135.
