Description
Product Overview
Join matching 12–10 AWG conductors with the Install Bay YNBC-5 nylon butt connectors. This 500-piece package supplies yellow insulated inline splices for building or repairing wiring connections where a permanent crimped joint is preferred over a removable plug.
The nylon sleeve insulates the crimp area and provides resistance to abrasion and impacts. The butt-splice layout accepts wire ends from opposite sides, keeping the splice in line with the harness rather than adding a stud or blade connection. The 500-piece bag offers a larger replenishment quantity without changing the specified wire range.

Selection and Installation Notes
Check the conductor size at both ends of the splice and use a crimping tool appropriate for the 12–10 AWG connector. Prepare the wire without cutting strands, crimp each end securely, and inspect and gently pull-test the finished connection with the circuit de-energized. The nylon sleeve is not a stated waterproof or adhesive-lined heat-shrink seal.
Frequently Asked Questions
How many connectors are included?
This YNBC-5 listing is one package of 500 individual butt connectors. The listed price is for the package, not one loose connector.
Is this a removable connector?
No. A butt splice is a crimped wire joint, not a male/female disconnect. Choose a mating disconnect system if the circuit needs regular separation.
Can I choose the size from the insulation color alone?
Use the specified 12–10 AWG range and the YNBC-5 part number. Color helps identification but does not replace checking wire size.
Is a crimp tool included?
This package contains connectors only. Use a suitable crimping tool and follow the installation requirements for the circuit.
