ElectroThread™ Monolithic Isolation Joints

Jump To Section:

The ElectroThread™ monolithic isolation joint is a compact, threaded isolation solution designed for smaller line sizes. Factory-assembled and maintenance-free, it provides a reliable block against the flow of electric current in piping systems. The ElectroThread™ eliminates the weaknesses of traditional unions by offering superior electrical isolation, improved sealing integrity, and long-term durability. Each unit is hydrostatically and electrically tested to ensure performance, and is manufactured under an ISO Quality Management System, with full certification provided.

Features & Benefits

Maximum Safety

Prevents stray currents and cathodic protection interference, reducing the risk of leaks, sparks, and premature bolted-joint failure.

Factory-assembled and maintenance-free

Expertly controlled assembly ensures long-term stability for both sealing and isolation, lowering operational expenses (OPEX).

Compact threaded design

Optimized for smaller line sizes (½" to 1"), addressing under-designed bolted joints and operational blind spots.

Improved Reliability Compared to Traditional Unions

Rugged, high-performance isolation outperforms low-cost unions that are prone to installation damage and component aging.

Tested for integrity

Hydrostatically and electrically tested to verify design integrity, meeting international quality and safety standards

Versatile applications

Suitable for utility service lines, residential hot water systems, electrical and SCADA conduit, and PHMSA-regulated pipelines.

Certified quality

Manufactured under ISO Quality Management systems and supplied with EN 10204/3.1 certification.

Applications

  • Pipeline integrity protection – ensures cathodic protection effectiveness in oil, gas, and water distribution.
  • Residential & Commercial Utilities – ideal for hot water heater isolation and small service lines.
  • Regulated Pipeline Systems – supports compliance with PHMSA rules requiring isolation near actuated valves.
  • Desalination & Water Treatment – prevents salt bridging in older or high-exposure systems.
  • OEM Skids & Packages – compressor, pump, and chemical injection skids where compact, leak-proof joints are critical.
