Garlock CHEVRON® packing is the original automatic hydraulic and pneumatic design for sealing rods, pistons, and plungers. This hydraulic 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.

                                      的独特和独家hinge-like行动each CHEVRON® ring permits immediate reaction even to minor pressure changes. Each individual lip of a CHEVRON® packing set independently reacts to pressure, and automatically effects a seal. The multiple lip configuration automatically distributes pressure and an effective seal along the shaft. The proprietary design of Garlock CHEVRON® packing also permits an automatic reaction to pressure shock and overloads. Once Garlock CHEVRON® packing has been selected and installed, it will seal effectively and automatically. CHEVRON® is now available in Deep V-ring design.
