Russell 1/4NPT X 8mm5/16") Hose Single Barb Fitting

EDELBROCK MANIFOLD FITTINGS 

These fittings are required when adapting metric size hose to standard NPT inlets/outlets. They eliminate having to force the hose over an oversized barb or excessive overtightening of the worm gear clamp to achieve a positive seal. Ideal for use with Edelbrock Victor X manifolds.
