A Look at Conduit Fittings from Industry Leaders

Conduit fittings ensure that electrical wiring remains functional through complex routing transitions, all while shielding it from moisture, dust, temperature fluctuations, and physical impact. Given that these items directly influence the durability, and in some instances, compliance of installations, an array of manufacturers offer solutions tailored to various environments and technical requirements. This blog will aid you in making informed purchasing decisions by highlighting a few companies that produce high-performance conduit fittings.

Hubbell Wiring Device-Kellems

Hubbell’s Kellems brand makes metallic liquid-tight conduit fittings that provide robust strain relief and environmental protection, featuring:

• Liquid-Tight Gland Design: Many of their fittings use a hexagonal compression nut to tighten a gland ring around the conduit, creating a secure hold. Additionally, a nylon gasket at the hub creates a liquid-tight seal, while a separate steel ferrule reinforces the connection and prevents the conduit from pulling out.
• Wide Temperature Resistance: Hubbell’s spec sheets list an operational range from –60?°F to +1000?°F (–51?°C to +538?°C), depending on the type and material choice.
• Compliance with UL and CSA Standards: These fittings are Underwriters Laboratories (UL) Listed and Canadian Standards Association (CSA) Certified to meet liquid-tight requirements, also meeting strict standards for environmental rating and hazardous locations.

RACO® (Hubbell)

RACO®, another Hubbell brand, holds a strong reputation in the electrical-conduit space for its liquid-tight connectors, built to secure flexible metal or non-metallic Type B conduit to enclosures. They offer:

• Integrated Split Gland-Rings, Locknuts & Sealing Washers: Almost every RACO® liquid-tight connector has a patented split gland ring that slips over the conduit jacket to grip tightly and prevent pull-out. This is paired with an integrated sealing washer and a heavy-duty zinc-plated locknut that ensures grounding continuity and maintains a tight seal.
• Reusability: All integrated components can be taken apart and reinstalled, even years later.
• Corrosion Resistant Materials: Bodies and nuts are made from zinc-plated malleable iron or steel, making them suitable for wet locations.
• Certifications & Hazard Ratings: These conduit fittings are UL 514B listed and CSA certified, as well as are approved for use in hazardous locations.

Thomas & Betts (ABB)

Now part of ABB, Thomas & Betts’ Steel City® line specializes in durable fittings built for industrial and marine settings. Their liquid-tight units are specifically designed to defend against chemical and moisture ingress, being known for their:

• Stainless Steel or Zinc-Coated Steel Construction: Fittings are available in 304 stainless steel or zinc-plated steel/malleable iron to resist salt, chemical exposure, and corrosion.
• Sealed Threads: All units use NPT threads with pipe-stop features that facilitate secure mechanical and dielectric integrity.
• Flexible Design Compatibility: These liquid-tight fittings have variants for both metallic and non-metallic conduits across standard trade sizes.
• NEC and UL Compliance: Thomas & Betts conduit fittings match North American safety and installation codes.
