Edelbrock/Russell 697020 1/4" NPT x 8mm Single Barb Manifold Fitting
Product Description
The Edelbrock/Russell Manifold Adapter
Fittings are meant to be used while adapting metric size hoses to
standard NPT (National Pipe Tapered) inlets/outlets. They eliminate
having to force the hose over an oversized barb or excessive
over-tightening of the worm gear clamp to achieve a positive
seal.
