Harsh-Environment Screw-Down Butt Splices




Join wires and cables in some of the dirtiest and wettest locations—from paper mills to marine environments—without special tools. With a nylon body and gasketed end caps, these splices are IP68 rated to seal out dust and water even if briefly submersed. To install, insert wire into either side, tighten the screws with a slotted screwdriver, and twist on the end caps to seal. They have multiple terminals, so you can repair, extend, and reconfigure cables with multiple wires.

High Temperature Twist-On Wire Splicing Connectors

Rated to 300° F, these connectors are an excellent choice for use in high-temperature applications such as HID lighting and electric heat. Use them to make quick, secure wire connections without crimping.
Connectors with a set screw have an inner barrel with a set screw that firmly holds wires to provide a secure grip in high-vibration applications.

Multi-Way Taps/Splices





Tap and splice multiple wires together at the same time. Insert your main wire into a port and each tap wire into the other ports before tightening the screws. All are fully insulated with PVC. UL listed, they meet U.S. safety standards.
For splices with through holes, one side of each port must remain open.
Splices with plastic plugs cover the screw openings to keep contaminants out. Splices with through holes and plastic plugs let you close entry ports that aren’t in use.
Use black, blue, and clear splices with Class B and C stranded wires. Clear splices help you confirm the connection visually.
Use gray splices with Class B, C, and D stranded wires.
Splices that are C-UL listed meet Canadian safety standards.

Sealed Multi-Way Taps/Splices




Tap and splice multiple wires in temporarily wet environments and up to six feet underground. Made with an EPDM rubber housing, these splices are fully insulated. Trim-to-size wire port plugs create a tight seal for wire entry, and removable screw-in plugs with double O-rings tightly seal the screw openings.

Set Screw Lugs
The straight tongue improves conductivity by increasing the surface contact between the lug and your equipment. Tighten the set screw onto your wire for a secure connection without crimping. Mount lugs to a screw.
Copper lugs can be used in large power distribution systems, motors, and generators.
Aluminum lugs are more lightweight and can be used in electrical distribution systems.
