Hose Adapters connect hoses of incompatible diameter, thread, or gender. Our adapters are manufactured from 6061-T6 aluminum and are “Hardcoat Anodized”--A very specific type of anodizing that gives aluminum parts greater abrasion and corrosion resistance than that provided by the more conventional plain anodizing processes.

Hose Thread Reducers connect a larger hose thread to a smaller one. The female thread is always larger than the male thread.
