HPS Performance AN816-8-M14125 AN-8 to M14x1.25 Straight Metric Adapter Fitting Black Aluminum

The HPS Performance AN816-8-M14125 is a straight AN flare to metric adapter fitting that converts a female M14 x 1.25 metric threaded port to a male AN-8 (37-degree) flare connection. Metric fittings are common in OEM automotive applications, but repeated servicing with a crush washer seal can become inconvenient over time. This adapter provides a clean, permanent solution by converting that port to a standard AN-style fitting for fast, tool-friendly serviceability.

AN-style connections can be assembled and disassembled repeatedly without sealants, gaskets, or thread tape, making them ideal for performance builds, custom plumbing, and any application requiring regular maintenance access. An aluminum crush washer is included for sealing on the metric side.

Key Features:

• Side A: Male AN-8 (37-degree flare)
• Side B: Female M14 x 1.25 metric thread
• Style: Straight
• Material: 6061 aluminum with Type II black anodizing for superior corrosion and abrasion resistance

Machined from lightweight 6061 billet aluminum and finished with a Type II black anodize, this adapter is built to withstand the demands of racing and high-performance street applications while maintaining a clean, professional appearance.
