-16 Plastic Caps 10pk

The ALLSTAR PERFORMANCE -16 Plastic Caps 10-pack (ALL50807) provides essential protection for -16 AN fittings and ports in hydraulic, fuel, and coolant systems. These red plastic dust caps seal unused AN connections during assembly, storage, and transport, preventing contamination from dirt, moisture, and debris that can compromise system integrity and performance.

Designed for -16 AN port sizing, these caps fit the standard 1.5-inch hex body diameter specification common across automotive, marine, and industrial hydraulic applications. The plastic construction offers chemical resistance to common fluids while remaining lightweight and easy to install and remove by hand. A 10-pack quantity ensures adequate coverage for multi-system builds or replacement stock. The bright red color provides quick visual identification of capped connections on complex manifold assemblies and plumbing layouts.

These caps are essential for drag racing, street performance, off-road vehicles, and marine applications where AN fittings are standard. Engine builders, hydraulic technicians, and enthusiasts use caps like these during initial setup to keep ports clean before final system pressurization. Replacement caps are equally important for maintenance work when disconnecting lines temporarily. ALLSTAR PERFORMANCE is recognized in the racing and performance automotive sector for producing cost-effective, reliable hardware solutions.

AN fittings are standardized across racing, marine, and high-performance applications where reliability and leak prevention are critical. These plastic caps represent basic but indispensable system maintenance — protecting connections that can be expensive to repair if contaminated.
