When choosing butt splices, pay special attention to whether they are lined with epoxy resin.
A butt splice is a combination of wires to complete an electrical circuit. Although they are ideal for new wire and cable installations, butt splices can be just as useful when replacing old parts or performing maintenance.
How do you know if your existing butt splices need to be replaced? Did your butt splices fade? Did your butt splices crack? If so, then maybe it’s time to replace these splices with new ones.
Butt splices have a range of insulation types, so you can find the exact style you need.
Suitable for use with marine wire, Yqunique provides non-insulated butt splices, nylon butt splices, vinyl butt splices, and heat shrink butt splices.
It is important to note that when dealing with marine applications, you should only use marine-grade butt splices.
Without ocean-grade butt splices, your electrical connections are vulnerable to harsh ocean conditions.
