Pico Wiring Butt Connectors

Pico Wiring Butt Connectors: Dependable Splices for Automotive Electrical Work

When it comes to splicing wires cleanly and reliably, few names carry as much weight in the automotive electrical aftermarket as Pico Wiring (Pacific Industrial Components). With over 50 years of experience supplying wire and terminal products to the automotive aftermarket and related industries, Pico has built a reputation for offering broad coverage and consistent quality across its connector lineup — and their butt connectors are a prime example of that commitment.

Two Distinct Technologies for Every Job

Pico Wiring's butt connector selection is anchored by two core product types, each designed to suit different working environments and connection requirements:

• Vinyl Flare-Insulated Butt Connectors — These are the workhorses of everyday automotive wiring repair. Featuring a butted-seam barrel construction with a flared vinyl insulating sleeve, they provide a solid crimp connection and are color-coded by gauge for fast identification. The 1800KT series, for instance, covers the popular 16–14 AWG (Blue) range and comes in packs of 20, making them ideal for shop use or bulk repair jobs.
• Crimp & Heat Shrink Butt Connectors — For applications demanding waterproof and corrosion-resistant connections, Pico's heat shrink series (such as the 2254A, 2260A, and 2270G) combines a crimp barrel with an adhesive-lined heat shrink sleeve that seals tightly when heated. This dual-action design locks out moisture and oxidation, making these connectors a go-to for underhood, marine, and exterior wiring runs.

Full AWG Coverage in One Brand

Pico Wiring structures its butt connector lineup across the full spectrum of common automotive wire gauges, from fine 22–16 AWG applications all the way up to heavy-duty 12–10 AWG runs. Color coding follows the industry-standard system — red for small-gauge (22–16 AWG), blue for mid-range (16–14 AWG), and yellow for heavier wire (12–10 AWG) — so technicians can grab the right connector at a glance without stopping to read packaging.

Assortment Kits for the Prepared Installer

Beyond single-gauge packs, Pico offers assorted connector kits like the 0040PT and 8396PT that bundle multiple AWG sizes into a single resealable package. These kits pair butt connectors with complementary terminals — rings, spades, and quick-connects — so professional installers and DIYers alike can tackle varied wiring tasks without sourcing multiple part numbers. The resealable packaging keeps unused connectors organized and protected between jobs.
