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.

Our cylinders are typically threaded pipe with threaded couplings that are welded on one side in the shop and they are screwed together and weided on the other side in the field, this provided a straight assembly.

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.
