Steel Plugs 3/16in Inv Flare 4pk

The ALLSTAR PERFORMANCE Steel Plugs 3/16in Inverted Flare 4-pack (SKU ALL 50183) provides a reliable solution for sealing inverted flare brake line fittings in high-pressure hydraulic systems. These cadmium-plated steel plugs are engineered to close off unused 3/8-24 inverted flare ports, preventing fluid loss and contamination during assembly, maintenance, or system reconfiguration. The male hex head design allows straightforward installation and removal using standard wrenches or flare nut tools.

Each plug in this four-pack is manufactured from steel with cadmium plating, a finish that resists corrosion in harsh environments and provides extended service life in moisture-prone applications. The inverted flare male configuration ensures proper sealing when threaded into female inverted flare ports—a standard connection type in automotive brake systems, fuel delivery lines, and custom hydraulic assemblies. The 3/16-inch size matches common smaller-displacement or precision applications where standard larger plugs would be inappropriate.

These plugs serve technicians, hot rodders, custom fabricators, and restoration specialists who work with vintage or modified brake and fuel systems. Whether capping off unused ports during system redesign, protecting threads during transport, or managing evolving circuit configurations, a dedicated set of inverted flare plugs eliminates improvised blocking methods that risk thread damage or leakage. The four-pack quantity provides spares and coverage for multiple vehicle projects or shop applications.

ALLSTAR PERFORMANCE is a recognized brand in automotive performance and restoration markets, with long-standing credibility in high-quality fasteners, fittings, and connection components. These steel plugs represent a straightforward, cost-effective choice for anyone maintaining or building hydraulic systems that demand precise, leak-free port management.
