Catamount TV4 Vinyl-Insulated Butt Splice, Tin-Plated Copper

The Catamount TV4 is a vinyl-insulated butt splice engineered for reliable, code-compliant conductor connections in the #22-#16 AWG wire range. Constructed from tin-plated copper and rated for 600V at a 75 Degrees C temperature rating, this splice connector delivers a secure, low-resistance joint for electrical and control wiring applications. The TV4 is available in Blue, Red, and Yellow color-coded vinyl insulation for easy wire-range identification, and measures .986 Inches in length with an outer diameter of .157 Inches and an inner diameter of .067 Inches, making it a precise fit for small-gauge conductors.

Key Features

Catamount TV18-BS-XV – Frequently Asked Questions

1) What wire gauge does the Catamount TV4 butt splice take?
The TV4 vinyl-insulated butt splice is built for #22 to #16 AWG stranded or solid copper conductors. Its barrel inner diameter is .067 inches, so anything heavier than #16 will not seat and will not crimp properly. For larger conductors you need a bigger splice in the series.
2) Blue, Red, or Yellow TV4 butt splice, what is the difference?
Color is the wire-range identification code on the insulation, and the three TV4 part numbers differ by it: Yellow is TV10-BS-XV, Blue is TV14-BS-XV, Red is TV18-BS-XV. All three are vinyl (PVC) insulated, tin-plated copper, rated 600V at 75 degrees C. Pick the color that matches your shop's convention or the existing harness.
3) Which crimp tool do I use on the Catamount TV4 splice?
The specified application tool is the WT112M. Insulated-barrel splices like the TV4 need a tool matched to the barrel so the crimp compresses the metal sleeve through the vinyl without cutting it; standard uninsulated-terminal dies will damage the jacket.
4) Is the Catamount TV4 butt splice UL Listed and good for 600V control wiring?
It is UL Listed under UL E9809 and rated 600V at 75 degrees C, which covers control panel and cabinet wiring, lighting circuit connections, and low-voltage repairs. Keep the conductor's own insulation temperature rating in mind: the splice tops out at 75 degrees C.
5) How many Catamount TV4 butt splices come in a pack?
The order unit is a pack of 100. Larger packaging tiers run 75 per inner carton and 900 per outer box, which is how it ships for shop or fleet stocking.
6) Will a tin-plated copper butt splice hold up in a damp or outdoor junction box?
The barrel is copper with a tinned surface for corrosion resistance, and the jacket is PVC. That handles general industrial and maintenance environments, but a vinyl-insulated crimp is not a sealed connection. If the splice will sit in standing water or direct weather, use a heat-shrink or adhesive-lined splice instead of a vinyl one.
7) Will the TV4 splice fit inside a tight harness or conduit run?
Overall length is .986 inches with a .157 inch outer diameter, so it adds under an inch to the run and stays slim enough for bundled control harnesses and automotive looms. Stagger adjacent splices in a bundle so the barrels do not stack up at one point.
8) What makes the Catamount TV4 grip the wire better than a plain barrel splice?
Two features: internal serrations inside the barrel that bite the conductor strands for retention, and a brazed tubular seam so the barrel does not split open under crimp pressure. The entry is also expanded, which makes feeding small #22 AWG strands in from each end faster.
