Hydraulic Components

Hydraulic components include heavy-duty seals to meet the demanding requirements of today’s reciprocating equipment. Key hydraulic component products include CHEVRON® V-ring packing, GARTHANE® urethane seals and SLUDGE-PAK® for vertical sludge pumps. Also offered are polytop sets and turbine runner blade packing for hydroelectric applications.

In 1928 Garlock Palmyra developed its Chevron® packing, the first automatic hydraulic packing using standard duck and rubber tubing, which it continues to manufacture. This packing was subsequently expanded from its original use in steam engines to applications in the off road equipment, power generation and automotive industries. Since then the global growth of Chevron® hydraulic packing has continued in the oil and gas and nuclear industries.

Polytop Sets

Garlock Polytop Seal Sets for high sealing efficiency. Unlike typical vee sets, Polytop Sets need no axial preload or adjustment after startup, virtually eliminating the fear of catastrophic failure.

Polytop Sets


Hydraulic packing sets are designed to reduce the friction and abrasion so often associated with vertical sludge pumps.


Turbine Runner Blade Packing

Double Reversed Packing for Turbine Runner Blade and Hydroelectric Applications.

Turbine Blade Runner Packing

Well Service Packing

Maximum sealability for high pressure well service pumps. Developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing and cementing pumps.
