The ALEX® Galvanized Threaded Coupling is a heavy-duty industrial fitting designed to securely join two lengths of threaded Rigid Metal Conduit (RMC) or Intermediate Metal Conduit (IMC).
Manufactured from high-grade steel with a hot-dip galvanized finish, this coupling ensures continuous ground conductivity and exceptional protection against corrosion. It is the standard solution for extending conduit runs in harsh industrial environments, commercial buildings, and outdoor infrastructure.
Key Features & Benefits
Secure Threaded Connection: Precision-machined internal threads provide a tight, vibration-resistant joint between conduits.
Corrosion Resistance: The galvanized coating offers superior durability against rust, moisture, and chemical exposure.
Structural Integrity: Heavy-wall construction protects conductors from physical damage and crushing.
Metric Compatibility: Designed to fit IEC standard threaded conduits ranging from 20mm to 110mm.

Frequently Asked Questions (FAQ)
Q: What is the difference between this coupling and an EMT coupling?
A: This is a Threaded Coupling designed for heavy-duty Rigid conduits (RMC) that have threaded ends. EMT couplings (Set-screw or Compression) are used for thin-wall, unthreaded tubing. They are not interchangeable.
Q: Can this coupling be used outdoors?
A: Yes. The galvanized finish is specifically designed to withstand outdoor weather conditions, preventing oxidation and maintaining the integrity of the raceway system.
Q: Do you offer OEM branding?
A: Yes. We support OEM production. We can customize packaging (boxes/bags) with your brand logo and part numbers to facilitate distribution.
Q: What is the lead time for bulk orders?
A: Our standard lead time is approximately 4 weeks. We recommend confirming specific delivery schedules with our sales team before placing large orders.
Q: Can I get technical data sheets?
A: Yes. ALEX supplies full technical specifications and compliance documents upon request to meet project requirements.
