Permanent. Thread-Free. Waterproof.

Hydraulic Crimping Couplers use high-pressure swaging to create a permanent, threadless connection, ideal for harsh and hard-to-access environments.

Installed using hydraulic pressure to crimp sleeve onto rebar

Creates strong friction-based mechanical interlock

Permanent connection (cannot be loosened or removed)

No threads, grout, or torque tools required

Go/No-Go gauge ensures correct installation

Ideal for tunnels, underground, coastal, and submerged applications

No Thread
Waterproof
Confined

Why Hydraulic Crimping?

  • Completely Thread-Free: 
    No thread cutting, rolling, or inspection required, eliminating all thread-related quality risks and equipment costs.
  • Confined Space Ready: 
    Compact hydraulic jaw profile allows crimping in spaces where no other mechanical splice tool can operate.
  • Inherently Waterproof:
    Swaged sleeve seals around bar ends, no grout, sealant, or additional waterproofing treatment needed.
  • Permanent & Tamper-Proof:
    Plastic deformation creates an irreversible bond, vibration-immune and impossible to undo without destroying the coupler.

Three Steps to a Permanent Bond

Insert Bars

Both bar ends are inserted into the sleeve from each side, no end treatment of any kind required.

Position Press

Hydraulic crimp press jaws are positioned centrally over the sleeve at the specified crimp locations.

Crimp

Press is actuated to full pressure, 500–1000 bar depending on bar size,  deforming the sleeve permanently.

Gauge & Record

Go/no-go gauge confirms correct sleeve OD after crimping. Result is recorded and connection is certified.
