Get Seamless Joint Integrity with Simultorc

Get superior leak protection with synchronized multi-tool fastening.

The Problem

Pipe and flange leaks, often caused by gaps, insufficient gasket stress, or joint misalignment, pose significant risks. These leaks can lead to product loss, hazardous emissions, profit loss, environmental damage, potential for costly fines, and safety issues.

The Solution

Simultorc — bolting with multiple tools simultaneously — results in an even seal, which is crucial for leak prevention. It makes bolting safer, faster, and more accurate. This process of parallel joint closure (also called parallelism) is ASME approved.

How does it work?

Simultorc prevents joints from becoming misaligned due to uneven or improper bolt loading. It also keeps gasket stress even and reduces the chances of leakage thanks to more thorough and consistent bolt application.

What can Simultorc do for you?

Technicians bolting a large horizontal vessel flange with several hydraulic tools at once.

Improves bolting efficiency while increasing the quality of the joint closure.

Parallel joint closure helps maintain flange alignment by bolting with several tools simultaneously. Using this with proven tightening sequences can ensure the gasket is not overstressed.

Prevents joints from becoming misaligned because of bolt loading.

Compatible with all HYTORC hydraulic, pneumatic and electric torque tools, as well as with the HYTORC Washer.

Keeps gasket stress even throughout the bolt loading process, meaning less gaps.

  • Reduces the chances of leakage due to a more thorough and consistent application of gasket stress.
  • Bolting preloading productivity increased.

The versatility that you need.

Works with any kind of bolting tools when they are applied simultaneously using established bolting patterns. Using parallel joint closure with the HYTORC Washer and the HYTORC Nut makes bolting more efficient.

Best Practice

The use of multi-tool bolting is recognized by ASME as an approved method for flanged joint assembly, per ASME PCC-1-2026 (Pressure Boundary Bolted Flange Joint Assembly).
