Hose Thread 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 anodize that gives aluminum parts greater abrasion and corrosion resistance than that provided by the more conventional plain anodize processes. Hose Thread Increasers are used to connect a smaller hose thread to a larger one. The male thread is always larger than the female thread.
