About Conduit

Compare rigid and flexible conduit materials and identify the trade size for compatible fittings.

Conduit and Cord Grip Thread Adapters

Connect mismatched conduit and cord grip threads while sealing out moisture. These adapters have a rubber O-ring that prevents water damage inside your electrical box or enclosure. They convert metric, NPT, and PG threads.

Nickel-Plated Brass—The plating enhances the corrosion resistance of brass, adding a durable protective finish.

Nylon—Lightweight and chemical resistant, these fittings won't corrode.

Flexible Plastic (MPT) Conduit and Fittings

Bend, twist, and wrap machine wiring through tight spaces. Corrugated like ENT, this conduit is more resilient against repeated flexing. Pair it with compatible fittings to seal out liquid and protect wiring indoors and outdoors. Conduit and fittings are made of nylon to resist moisture and chemicals.

EMI-Shielding Flexible Plastic (MPT) Conduit and Fittings

A braided copper cover defends against electromagnetic interference (EMI) that can distort or disrupt signals. Install shielded MPT in areas where motors, generators, and other equipment that emit EMI are running. It has a corrugated nylon core that flexes to make tight bends and is typically used indoors. Pair conduit with nickel-plated brass connectors for a fully shielded run.

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They also have high strength and impact resistance.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Key-Locking Threaded Inserts for Soft Metal

Add strong threads in soft metal, such as aluminum. The keys on these inserts drive into holes to hold more securely than thread-locking or helical inserts. They prevent slipping and rotating, so they’re stable enough for use in vehicle or aerospace parts that experience heavy vibration. These inserts are comparable to Keensert inserts.

To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Black Phosphate-Coated Steel—These inserts resist occasional moisture.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

Key-Locking Threaded Inserts with Installation Tools

Paired with the right tool for installation, these inserts create strong threads in soft metal, such as aluminum. They have keys that drive into material to prevent inserts from slipping and rotating in the hole.
