Gratux Metri-Pack 280 Series 2-Way Sealed Connector Kit (3-Set) — 10–12 AWG, 30A Waterproof

This three-set Gratux kit contains complete APTIV Metri-Pack 280 Series components designed for durable, space-saving in-line connections where heat, chemicals, vibration and moisture are concerns. Rated to handle up to 16 volts and 30 amps, the kit includes male and female housings, crimp terminals, terminal position assurance (TPA) pieces and cable seals so you can assemble sealed splice packs or replace worn connectors without sourcing parts separately.

How do these connectors perform in harsh environments?

The Metri-Pack 280 Series was engineered for under-hood and off-road duty, offering resistance to temperature extremes, oils, fuels and abrasion. The sealed system and retention features help keep moisture and contaminants out of the electrical contact area to maintain reliable connectivity over time.

• Sealed cable seals prevent water intrusion and corrosion.
• Materials resist chemical exposure common in automotive settings.
• Low engage force reduces wear during repeated mate/unmate cycles.
• Seal retention and protection features minimize accidental seal loss.

What electrical capacities and compatibility should I expect?

This kit supports medium-duty wiring: 10–12 AWG conductors with a continuous rating up to 30 amps at 16 volts. The contacts and housings are compatible with ISO and SAE blade styles, offering interchangeability with many existing vehicle and equipment wiring systems.

• Rated up to 30 A and 16 V for common accessory and sensor circuits.
• Includes crimp male and female terminals for standard 10–12 AWG wire.
• Mates with ISO/SAE blades to integrate into established harnesses.
• Passes SAE J2030 heavy-duty connector criteria when plated accordingly.

What’s included in this Gratux three-set package and how does it simplify installation?

Gratux bundles all necessary pieces to build three sealed 2-way in-line connections so you won’t need to buy terminals or seals separately. Each set contains matching male and female housings, the correct number of crimp terminals, TPAs to lock terminal positions, and blue cable seals sized for 10–12 AWG conductors.

• 3 male and 3 female 2-way APTIV housings for three connections.
• 6 crimp male and 6 crimp female terminals for secure wire termination.
• 6 TPA pieces to ensure terminals stay engaged and indexed.
• 12 blue cable seals to properly seal both sides of each connector pair.

How easy is assembly and long-term maintenance?

Crimp-style terminals and TPAs make assembly straightforward with common crimp tools, while the low engage force reduces strain during mating. For longevity, use correct crimp die sizes, inspect seals for damage before installation, and replace seals or terminals if signs of corrosion or wear appear.

• Crimp terminals require standard crimp dies for reliable contact.
• TPA locks improve assembly confidence and prevent backout.
• Inspect seals and contacts during routine service for durability.
• Designed for easy replacement in confined engine bay or control locations.

Who is this for? If you wire, repair or maintain vehicles, boats, off-road equipment or agricultural machinery and need a compact, sealed two-circuit connector that handles medium currents, this Gratux Metri-Pack 280 Series kit supplies all components for three robust in-line connections. It’s aimed at mechanics, fleet technicians, custom fabricators, and experienced DIYers who want OEM-compatible, sealed electrical connections without sourcing parts individually.
