Thomas & Betts OCAL CPL3-G 3" PVC-Coated Rigid Conduit Coupling

The Thomas & Betts OCAL CPL3-G is a 3" PVC-coated rigid conduit coupling engineered to join two lengths of rigid conduit while shielding the connection point from corrosion, moisture, and chemical attack. As part of the Thomas & Betts OCAL line of PVC-coated conduit and fittings, this coupling pairs a rigid (RIG) conduit design with a tough exterior PVC coating (CTD) for dependable long-term performance in demanding environments. The 3" trade size matches standard 3" rigid conduit runs, giving electrical contractors a straightforward, code-friendly way to extend, splice, or repair conduit systems without compromising corrosion protection along the run. This coupling is intended for professional electrical installations where corrosion resistance and code compliance are priorities.

Key Features

  • Trade Size: 3" trade size is sized to connect directly to standard 3" rigid conduit sections.
  • PVC-Coated Construction: The exterior PVC coating (CTD) forms a protective barrier against corrosion, moisture, and chemical exposure that would otherwise attack bare metal fittings.
  • Rigid Conduit Coupling: Rigid (RIG) coupling (CPLG) construction provides a secure, code-compliant mechanical connection between two lengths of rigid conduit.
  • OCAL Product Line: Manufactured as part of Thomas & Betts' OCAL series of PVC-coated conduit and fittings, built specifically for corrosion-prone job sites.
  • Simple Field Installation: Coupling design allows electricians to join, extend, or repair rigid conduit runs quickly while maintaining the coating's corrosion protection at the joint.
  • Consistent Coating System: Using OCAL couplings with OCAL PVC-coated conduit helps maintain uniform corrosion protection throughout the raceway.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Industrial and Chemical Processing Facilities
  • Wastewater and Water Treatment Plants
  • Coastal and Marine Electrical Installations
  • Outdoor and Corrosive-Environment Conduit Runs
  • Food and Beverage Processing Plants
  • Rigid Conduit System Extensions and Repairs

Why Thomas & Betts?

Thomas & Betts' OCAL PVC-coated conduit products are engineered to hold up in harsh, corrosive environments where standard rigid conduit fittings often fail prematurely. The CPL3-G coupling's PVC-coated, rigid construction reflects Thomas & Betts' long-standing focus on durable, code-compliant electrical infrastructure for demanding industrial, marine, and outdoor applications. Choosing OCAL fittings alongside OCAL conduit helps maintain consistent corrosion protection across the entire raceway system.

Ocal CPL1/2-G – Frequently Asked Questions

1) What trade sizes does the Ocal CPL Series PVC-coated conduit coupling come in?
Two trade sizes are offered in the Ocal CPL gray coupling: 1/2 inch (part CPL1/2-G) and 3 inch (part CPL3-G). Each is sized to thread directly onto standard rigid conduit of the matching trade size, so order by the conduit run you are joining.
2) Can I use an Ocal CPL coupling on plain galvanized rigid conduit, or does it have to be PVC-coated conduit?
The threads are standard rigid (RIG) conduit threads, so it will make up mechanically on standard rigid conduit of the same trade size. The reason to buy it, though, is coating continuity: pairing Ocal couplings with Ocal PVC-coated conduit keeps one uninterrupted corrosion barrier down the raceway. Join it to bare galvanized and the joint becomes the weak point in a corrosive area.
3) Why use a PVC-coated coupling instead of a standard steel conduit coupling?
The exterior PVC coating puts a barrier over the steel at the joint, which is where corrosion, moisture and chemical attack normally start first. On a wastewater plant, a chemical process area, a food and beverage washdown zone or a coastal install, a bare steel coupling in the middle of a coated run undoes the protection of the whole raceway. Indoors and dry, a standard galvanized coupling is enough.
4) Can I use this coupling to repair a damaged section in an existing rigid conduit run?
That is one of its intended uses. The Ocal CPL coupling joins two lengths of rigid conduit, so it works for extending, splicing or repairing an existing run. Match the coupling trade size to the conduit (1/2 inch or 3 inch are the gray CPL sizes) and the corrosion protection carries through the new joint.
5) Is the Ocal CPL3-G a threaded coupling or a compression type fitting?
Threaded. It is a rigid conduit coupling (CPLG) that makes up on the conduit's own threads to form the mechanical connection, so the conduit ends need to be properly threaded and reamed before assembly. There is no set screw or compression ring involved.
6) What color is the Ocal CPL coupling, and does the coating color matter for matching an existing installation?
Gray. The CPL-G suffix is the gray PVC coating, which is the standard Ocal finish, so it blends with existing gray-coated Ocal conduit and fittings on the same raceway. If the existing system on site is a different coating color, you are looking at a different product line.
