The Enerpac ERT-series, extended reaction tube for RSL torque wrenches, is a reaction accessory used to position the wrench reaction point on bolting jobs where standard tubes cannot reach the joint. Enerpac builds hydraulic bolting and tensioning equipment as part of a high-pressure catalog that spans hand pumps, electric pumps, cylinders, and presses, so reaction-tube fitment ties back to the specific RSL square-drive torque wrench it pairs with. If your wrench tag is worn or the original tube length is no longer offered, we cross-reference the part and match a current equivalent — request a cross-reference quote.
Reaction-tube selection follows the RSL wrench model and the reach you need at the joint, not the bolt size alone. Confirm the wrench frame the tube mounts to, then verify the tube length and the drive interface against the wrench data plate. Because these tubes are an accessory to the torque tool itself, fitment is easiest to confirm against the surrounding Enerpac bolting and tooling range. Cross-check the wrench in Enerpac hydraulic tools or the broader hydraulic tools line, confirm the pump driving the tool in hydraulic pumps, and review related lifting and pressing gear in hydraulic cylinders and hydraulic jacks. For supply lines feeding the wrench, see hydraulic hoses. If you are unsure which tube length your RSL wrench takes, send the wrench model and we confirm the match before you order.
Reaction tubes and other RSL accessories are exactly where part numbers go obsolete — a wrench stays in service for years while the original tube length is superseded or relabeled. Northern Hydraulics supplies Enerpac bolting equipment and cross-references discontinued Enerpac part numbers against current-production equivalents, so a legacy ERT tube reference can be matched to a tube that fits the RSL wrench you already run. Give us the wrench model, the old tube part number, and the reach you need, and we identify the replacement or equivalent. Request a cross-reference quote.
