8an x 1/4-MPT Straight Adapter Fitting - Steel

The 8AN x 1/4-MPT straight adapter fitting from FRAGOLA is a precision-engineered hydraulic and fuel system connector designed for professionals who demand reliable, leak-free connections in high-pressure applications. This steel adapter bridges two different thread standards—8 AN male and 1/4 inch NPT male—enabling seamless integration between components that would otherwise be incompatible. Whether you're building a custom fuel system, upgrading hydraulic lines, or assembling performance fuel injection plumbing, this fitting eliminates adaptor complications and ensures system integrity.

Constructed from durable steel with a zinc oxide protective finish, the 8AN x 1/4-MPT adapter resists corrosion and maintains structural integrity under demanding operational conditions. The straight-through design minimizes turbulence and pressure loss compared to elbowed alternatives, improving flow efficiency and system response. The 8 AN male end accepts industry-standard JIC hose fittings and line couplings, while the 1/4 inch NPT male side threads directly into female NPT ports found on fuel filters, regulators, manifolds, and tank fittings. This combination of materials and thread geometry ensures tight, reliable sealing without the need for secondary tape or sealant compounds in most installations.

Mechanics, fabricators, and enthusiasts building custom fuel systems, turbo circuits, and hydraulic setups will benefit most from this adapter's simplicity and proven reliability. The compact 3 x 1 x 5 inch profile fits tight engine bays and confined spaces where space is at a premium. Installation is straightforward—thread the NPT end into the female port, attach the appropriate AN hose fitting to the opposite end, and torque to specification. Always verify thread compatibility before purchase, and ensure adequate clearance around the fitting to prevent vibration contact during vehicle operation.
