Burndy HYLINK Seamless Uninsulated Copper Butt Splice Connector

The Burndy HYLINK™ Seamless Uninsulated Butt Splice Connector is a family of copper-to-copper splice connectors built for professional electrical, commercial, and industrial wiring applications. Available in conductor sizes ranging from 4 AWG to 9 AWG, this connector family is manufactured from electrolytic copper with a tin-plated finish for dependable electrical conductivity and long-term corrosion resistance. Each size is supplied as an uninsulated, seamless barrel splice with an integrated wire stop, giving installers a consistent way to join copper conductors across a wide range of wire gauges. Whether you're working on panelboard connections, motor leads, or general wire repair, the HYLINK line delivers the same seamless-tube construction and quality standards across every conductor size in the range.

Key Features

  • Conductor Size Range: Available from 4 AWG up to 9 AWG, allowing electricians to select the correct splice for the conductor being joined.
  • Durable Construction: Manufactured from electrolytic copper for excellent electrical conductivity, mechanical strength, and long-term reliability in the field across every size in the line.
  • Finish: Tin-plated exterior helps resist corrosion and oxidation while supporting a consistent, long-lasting electrical connection regardless of conductor size.
  • Seamless Barrel Design: Seamless tube construction provides uniform wall thickness, resulting in consistent crimp performance along the entire length of each splice.
  • Wire Stop Feature: A built-in wire stop marks the proper depth of wire insertion on each side of the splice, reducing installation error and improving connection integrity for every conductor size.
  • Uninsulated Design: Supplied as an uninsulated butt splice for applications where insulation, heat-shrink tubing, or tape is applied separately after crimping.
  • HYLINK™ Line: Part of Burndy's HYLINK™ family of splice connectors, engineered to a consistent standard of fit, form, and function across sizes.

Burndy YSV9CLBOX – Frequently Asked Questions

1) Which conductor sizes can I order the Burndy HYLINK seamless butt splice in?
Two sizes: 4 AWG (part YSV4CLBOX) and 9 AWG (part YSV9CLBOX). The HYLINK butt splice family spans 4 AWG through 9 AWG copper. Pick the splice that matches the conductor gauge exactly, since a seamless barrel splice is sized to one conductor size per end and will not crimp reliably on a gauge it was not made for.
2) Can I use these Burndy HYLINK splices on aluminum wire?
No. These are copper-to-copper splices, made of electrolytic copper with a tin-plated finish. For aluminum or aluminum-to-copper transitions you need a connector rated AL9CU or an aluminum-bodied compression splice instead.
3) Do these butt splices come insulated, or do I have to insulate them myself?
Uninsulated. The HYLINK barrel ships bare, so after crimping you insulate it yourself with heat-shrink tubing, tape, or a shrink sleeve. If you want a splice that comes insulated out of the box, this is not it.
4) How many Burndy HYLINK butt splices are in a box?
Each box is 100 pieces, which is how the CLBOX part numbers (YSV4CLBOX, YSV9CLBOX) are packaged. That makes it a stocking quantity for a truck or an MRO crib rather than a one-off repair purchase.
5) How do I know the wire is pushed in far enough on a HYLINK splice?
There's an integrated wire stop inside the barrel. Strip to length, push the conductor in until it bottoms on the stop, then crimp; repeat on the second conductor from the other end. The stop sets insertion depth on both sides so you get the same amount of conductor under each crimp every time.
6) Why choose a seamless barrel splice over a formed or seamed one?
Seamless tube construction gives uniform wall thickness with no joint running the length of the barrel, so crimp pressure is consistent end to end. A seamed barrel can open or deform at the seam under a heavy compression crimp. For panelboard connections, motor leads, and circuit extensions where the splice is buried and not coming back out, the seamless barrel is the safer build.
7) What does the tin plating on these copper splices actually do for me?
The tin plating is a corrosion and oxidation barrier over the electrolytic copper body. It matters most in damp, outdoor, or industrial atmospheres where bare copper would oxidize at the crimp interface and drive up resistance. Bare copper in a dry indoor panel would be fine, but tin-plated is the specification here across both sizes.
8) What kind of jobs is the Burndy HYLINK butt splice meant for?
Copper conductor splicing and termination in commercial and industrial wiring: panelboard and junction box connections, motor lead extensions, wire repair and circuit extension, and new construction or renovation work. It is a compression splice, so it needs the right crimp tool and die for the conductor size, and it needs insulating after the crimp.
