AP Astro Pneumatic Weather Pack Connector Kit 209-Piece — 1–4 Pin Housings, Silicone Seals

AP Astro Pneumatic 9476 is a 209-piece starter kit that supplies Weather Pack housings, terminals, silicone seals and a release tool to build 1–4 pin Delphi-style sealed connectors for 1.4–3.8mm wiring.

This compact kit gathers the core components technicians and hobbyists need to assemble weather-resistant automotive connectors without buying individual parts. It includes a range of male and female terminal receptacles, multi-pin housings, silicone wire seals sized for common conductor diameters, plus a terminal release tool so you can remove pins for rework or replacement. The set omits crimping jaws and the crimp tool itself, making it an economical way to stock up on consumables while still relying on your existing crimping equipment.

What connector types and pin counts are covered by this kit?

The kit contains both male and female pin types and plastic housings that support single-pin up to four-pin Weather Pack assemblies. That versatility lets you assemble inline splices, sensor plugs and small multi-conductor harnesses used across vehicles and equipment.

• Male and female terminal receptacles in three contact-size ranges (0.5–0.85mm, 1.25–2.0mm, 3.0mm)
• 1, 2, 3 and 4 pole male and female receptacle housings
• Additional 4-pin pin-style housings for specific pin configurations

Which wire sizes and sealing options does it support?

Silicone wire seals are included in three inner-diameter dimensions designed to fit conductors from roughly 1.4mm up to 3.8mm. These soft seals compress inside the housing to help block moisture and contaminants when assembled correctly, covering most common automotive and industrial wire gauges.

• Silicone seals sized 1.4mm, 2.5mm and 2.8mm for 1.4–3.8mm wire ranges
• Seals compatible with stranded and tinned conductors used in harnesses
• Seals pre-shaped to seat inside Weather Pack-style housings

What tools and accessories are included, and what do I still need?

The kit ships with a dedicated terminal release tool for extracting pins from housings during repairs or reconfiguration. It contains terminals and seals for many applications, but it does not include crimping jaws or the manual/electric crimper itself—those are required to complete reliable crimps.

• Includes one terminal release tool for safe pin removal
• Contains 208 consumable connector parts across housings, terminals and seals
• Requires a compatible crimping tool and dies for proper terminal crimps

Who this is for: The AP Astro Pneumatic 9476 starter kit is aimed at mechanics, electrical technicians, restoration hobbyists and DIYers who assemble or repair sealed electrical connectors on cars, trucks, off-highway machines and specialty equipment. It’s ideal if you already own a crimper and need a broad, cost-effective selection of Weather Pack terminals and seals for prototyping, maintenance or small-batch harness fabrication.
