Sierra Marine Hose (formerly Shields)
Even a small boat requires a lot of hoses to keep everything running efficiently. Sierra hoses (formerly Shields) are known for high-performance water hoses and accessories. Their rugged hoses will resist saltwater, exhaust fumes, antifreeze, UV rays, abrasions and certain chemicals to thrive in demanding environments. Softwall hoses offer the most flexibility, while wire-reinforced hardwall hoses are incredibly durable for straight-line connections.
Use the category filters to shop for bilge hoses, fuel system hoses, potable water hoses, exhaust hoses and many other necessary components that ship fast. We also have air conditioner duct hoses to keep passengers cool and wire conduits to protect sensitive electronics. Sierra hoses come in many lengths and diameters, and you can buy certain hoses by the foot. Add the right fittings for a secure connection.
