Plastic Hose Fittings & Adapters

Did you know that marine hose runs smaller ID than standard industrial hose?  That's why, even though fittings you buy at the hardware store are cheaper, they don't fit your boat's hose!  Also, they are usually molded in an inexpensive material like PVC which can break under stress or freezing conditions.  Every plastic hose fitting and adapter we carry is molded of high-strength materials with barbs to fit marine hose, designed so you can double hose clamp, if needed. All threads are standard tapered pipe thread, which fits most marine fittings. Our collection of marine hose barb fittings includes tee adapters, Y fittings, barb adapters, and much more. Shop our collection of plastic hose fittings and adapters for your boat today!
