Accumulator Adpt Fitting 13/16-16 to 2-5/8 O-Ring

The Moroso Accumulator Adapter Fitting 13/16-16 to 2-5/8 O-Ring is a crucial hydraulic system connector designed for high-performance engine builders and fuel system technicians. This fitting is particularly useful for those working with modern fuel accumulators and pressure regulation setups, allowing for seamless integration of components with different thread specifications.

Featuring a 13/16-16 thread port on one end and a 2-5/8 O-ring boss connection on the other, this adapter ensures proper hydraulic flow without leaks. The O-ring face seal design provides a robust, pressure-rated connection that eliminates the need for thread sealant tape, significantly reducing the risk of leaks in demanding EFI and fuel injection systems operating at 40–100+ PSI. Constructed from durable aluminum, this fitting is designed to withstand the thermal cycling and vibration typical of high-performance engine bays.

Ideal for custom fuel system builds and fuel cell installations, this adapter allows you to mate accumulators or fuel rails with different port configurations without the need for custom fabrication. Whether you're upgrading your fuel delivery system for a turbocharged engine or enhancing adjustable fuel pressure regulation, this fitting is a reliable choice for ensuring optimal performance.
