HERCULES Stuffing Boxes | The Hercules Difference

The Hercules Difference

Hercules stuffing boxes are recognized for superior quality and design unsurpassed in the industry. Hercules originated
cone-style packing and it quickly became the industry standard. Now with the advent of DOME packing, Hercules has
introduced a new concept destined to become an even greater standard. Both cone and DOME packing provide a tight
seal without the excessive tightening required for compression-type packing. Certain Hercules stuffing boxes have a unique
misaligning feature that
reduces the need for exact
alignment with the pumping
unit. The newer inverted cone
and DOME style packing
automatically compensate
for flow line pressures.

Today, Hercules continues

to set standards for quality
and dependability in the
oil field with new packing
designs, materials and the
most extensive line of stuffing
box models. No wonder
production personnel think
of Hercules first.
