Graco 150418 Leather Vee Packing

The Graco 150418 Leather Vee Packing is arranged within sealing assemblies to regulate fluid movement by forming layered contact surfaces that compress under pressure changes. It interacts with reciprocating components to control internal passage flow during repeated motion cycles and pressure variation phases. It is positioned inside pump housing sections where shaft-driven mechanisms operate and is placed around the piston rod area to support controlled alignment during movement cycles. It sits in a stacked configuration inside the sealing chamber and remains installed within the internal pump head assembly section.
