Power Seating Jack Parts

Cylinder seals, nose pieces, grippers and gripper retainer plates. Those four cover most of what a stressing crew replaces. Gripper blocks and gripper handles are longer-lived and normally only get replaced when something damages them.

By the anchor pocket and by the jack. Nose pieces come in several lengths, and 3 inch and 6 inch are the common sizes on single-acting jacks. Double-acting jacks take a wider range, including 3, 4, 6, 8, 10 and 12 inch. Tapered or recessed pockets need the longer ones. If you are unsure, tell us the jack model and the anchorage and we will match it.

Because they are doing the hardest job on the tool. Grippers use serrated teeth to bite the strand and hold it while the jack pulls. That is metal on hardened steel under load, every single cycle. They are a consumable, and crews that treat them as one keep working.

Yes, and it is the cheapest insurance in post-tensioning. A worn gripper or a failed seal stops a crew mid-pour, and a part that has to be ordered turns a ten-minute swap into a lost day. Carrying a small inventory of seals, grippers and nose pieces is what separates crews that finish from crews that wait.

Call and ask. We carry parts across the post-tension lines we supply. Call 832-671-0978 with the jack model and what failed, and we will tell you straight whether we have it.
