Hydraulic Jacks
Our Hydraulic Jacks are Manufactured to Meet Demanding Requirements
Whether selecting from our standard series of jacks or a custom application, all our jack products are designed to conform with ASME AI7.1 standards, State & Local codes, DOD, DOT, VA and OSHPD standards. All components pass through a rigorous quality control system throughout the manufacturing process.
When custom engineered jack assemblies are ordered, specifications are reviewed, approval drawings are communicated, and we thoroughly manage the order to ensure the highest level of safety and satisfaction possible.

Multi-Piece Replacement Pistons & Cylinders
Providing replacement jacks for single bottom cylinders, leaking jack units or any installation that requires multi-piece jack assemblies account for approximately 50% of our jack business.
Standard cylinders are typically threaded pipe with threaded couplings that are welded on one side at Bore-Max. After screwing sections together the coupling is designed to be field welded on the other side. The installation method insures a straight assembly. Alternatively, Bore-Max can supply weld-less couplings which utilize an O-ring system for sealing.
The pistons are precision threaded in the shop and ductile iron inserts are threaded into one side of the piston and assembled in the field. All joints on the piston are sealed with “O” rings.
Cylinder sections are coated with a rust prevention mastic. Tape wrap as an additional protection is available.
Piston sections are protected with a coating of protective oil and covered with waxed rust inhibitor paper.
Replacement custom buffer spring assemblies are available for most installations.
