183025-1 / 282109-1 Brass Tyco Crimp Terminal Splice Pins — Sealed Waterproof Connectors
The 183025-1 (male) and 282109-1 (female) are brass Tyco (TE Connectivity) crimp terminal splice pins designed for use with sealed waterproof automotive connector housings. Brass construction provides superior corrosion resistance and mechanical strength compared to standard copper alloy terminals — critical for sealed connector applications where the terminal is the last line of defense against moisture-induced corrosion. These terminals are used in Tyco sealed connector systems across a wide range of automotive, marine, and industrial wiring harness applications.

Brass vs Copper Alloy Terminals — Why It Matters for Sealed Connectors
- Superior corrosion resistance — brass (copper-zinc alloy) is inherently more corrosion-resistant than pure copper; critical for sealed connectors in underbody, marine, and outdoor applications
- Higher mechanical strength — brass terminals maintain their shape under the compression of wire seals and connector body seals, ensuring consistent sealing performance
- Tin plating for contact reliability — tin plating over brass provides a solderable, low-oxidation contact surface that maintains low resistance over the connector’s service life
- Tyco sealed system compatibility — 183025-1 and 282109-1 are designed to work with Tyco wire seals and sealed housing assemblies; using non-OEM terminals may compromise the seal integrity

Frequently Asked Questions
Q: Do I need to use wire seals with these terminals?
Yes — these terminals are designed for use in sealed waterproof connector housings that require individual wire seals. Thread the wire seal onto the wire before stripping and crimping. After crimping, the wire seal must seat correctly in the housing entry hole to achieve the waterproof rating. Using these terminals in unsealed housings is possible but wastes the brass construction advantage.
Q: What is the wire gauge range for 183025-1 / 282109-1?
Consult the Tyco/TE Connectivity datasheet for the exact wire range, as it varies by terminal variant. Generally, Tyco sealed series terminals in this size range accept 0.35–1.0mm² (22–18 AWG). Match the terminal to your wire gauge for a gas-tight crimp — an oversized wire barrel will not crimp properly and will fail under vibration.
