Earl's Performance LS Steam Vent Adapter Fittings

Earl's Performance Steam Vent Adapter Fittings are a professional-grade solution for managing steam and air evacuation in high-performance cooling systems. Engineered to eliminate trapped air and steam from the engine, these adapters help prevent hot spots and overheating that can result from the limitations of factory rigid hard line configurations — particularly when aftermarket intakes and accessories are part of the build.

Unlike OEM brazed vent tube manifolds that offer little flexibility for modified vehicles, Earl's steam vent adapters feature an adjustable outlet design with O-ring seal construction that converts existing ports to AN plumbing. This provides significantly more routing flexibility and a cleaner, more custom appearance compared to factory hard lines. Their low-profile, precision-machined design makes them among the most installation-friendly adapters available.

Key Features:

• Eliminates trapped air and steam from the cooling system to prevent engine hot spots and overheating
• Adjustable outlet design accommodates aftermarket intakes and accessories with flexible routing options
• O-ring seal construction ensures secure, leak-free connections
• Converts to AN plumbing for full compatibility with performance hose and fitting systems
• Low-profile, precision-machined construction for a clean, professional installation
• Multiple configurations available including single-outlet and dual-outlet options — dual-outlet versions eliminate the need for a separate T-adapter
• Suitable for street performance, road racing, and other demanding applications

Earl's Performance has been a cornerstone of performance plumbing technology for decades, trusted by professional racing teams and enthusiasts worldwide. Their steam vent adapter fittings deliver a durable, versatile upgrade over factory hard lines, improving both the function and appearance of any high-performance cooling system. Multiple variants are available to ensure optimal routing for virtually any application.
