10AN 90Deg Male Adapter to 3/8in NPT Male Blue

The 10AN 90Deg Male Adapter to 3/8in NPT Male in Blue by REDHORSE PERFORMANCE is an essential component for custom fuel, coolant, and hydraulic system builds where direct line connections require a directional change. This adapter bridges two critical industry-standard thread profiles—10 AN (JIC) fittings and 3/8-inch NPT ports—enabling installers to route hard lines around engine bays, fuel cells, and transmission coolers without compromising flow integrity or system pressure ratings. Whether you're upgrading a street rod fuel system, building a turbo coolant circuit, or fabricating a custom hydraulic assist setup, this 90-degree elbow prevents sharp bends that can restrict flow and reduce component lifespan.

REDHORSE PERFORMANCE adapters are forged from lightweight aluminum alloy and feature SAE-certified JIC threads that deliver precise sealing under sustained pressure—critical when working with fuel injection systems, nitrous oxide feeds, or high-temperature cooling loops. The 90-degree geometry reduces stress points that result from excessive hose routing, while the blue anodized finish resists corrosion and serves as a visual identifier in complex plumbing layouts. The male-to-male configuration allows this piece to thread directly into female receptacles on fuel rails, NPT-tapped manifolds, cooler inlets, and distribution blocks, eliminating the need for bulkier manifold fittings that eat up underhood real estate.

Experienced fabricators and engine builders rely on this adapter for custom fuel cell installations, turbocharger coolant plumbing, and nitrous oxide system assembly where OEM configurations don't accommodate aftermarket components. It's equally valuable in marine, ATV, and small-engine applications where NPT ports on water pumps or fuel blocks require conversion to AN-compatible hard lines. Ensure proper thread sealant application to NPT ports and verify 10 AN female receiver compatibility before installation; this adapter supports standard -10 AN hose sizes and works seamlessly in both low and high-pressure circuits within manufacturer specifications.
