-3 Plastic Plugs 20pk

The -3 Plastic Plugs 20pk from ALLSTAR PERFORMANCE are essential dust caps designed to protect AN-3 fittings from contamination during storage, transport, and assembly. These plugs serve a critical role in any shop environment, race paddock, or maintenance workflow where hydraulic, fuel, or pneumatic systems require protection from moisture, dirt, and debris. Keeping unused AN fittings sealed prevents expensive system failures caused by particle ingestion or oxidation, making this 20-pack an economical safeguard for technicians who work with multiple AN-3 connections simultaneously.

Constructed from durable red plastic, the -3 Plastic Plugs feature a tapered design engineered to fit snugly into AN-3 (3/16-inch) port openings without requiring tools or creating installation stress. The plastic material resists corrosion, remains lightweight, and withstands routine handling in high-activity shops without cracking or deforming. The bright red color coding ensures quick visual identification on crowded workbenches, reducing the risk of mismatched fittings or lost caps during complex assemblies. Each plug in the 20-pack is individually molded to consistent tolerances, guaranteeing reliable fit across all connections in your system.

Professionals in performance automotive, racing, aerospace, and hydraulic manufacturing rely on this 20-pack to protect AN-3 fittings in fuel rails, brake lines, coolant circuits, and air systems. The quantity supplied covers standard high-performance engine builds or complete brake system overhauls, eliminating the need for multiple smaller purchases. Installation is immediate—simply insert the plug into the AN-3 port until seated—and removal requires no special tools, making routine maintenance quick and hassle-free. Compatible with all standard AN-3 threads and fittings regardless of manufacturer.
