Depending on its type and application, a boat may contain different piping systems designed for bilge water removal, fresh and potable water supply, sanitary purposes, livewell, etc. All of these systems require regular inspection and maintenance, and in order to rebuild or restore them, you may need to replace some metal or plastic fittings and adapters. Such parts are typically installed in places where pipes pass through the hull or deck, change direction, or connect to various equipment, and all of them have to meet certain standards and marine regulations.

For instance, it's not recommended to use nylon thru-hulls and other plastic fittings at or below the waterline. In our online store, you can find a large assortment of elbows, couplings, tees, thru-hull fittings, in-line valves, and other products used for marine plumbing. Sourced from leading brands, they are available in numerous sizes and comply with the necessary regulations. However, before ordering any of them, make sure the thread of your line complies with our fittings. Most of them are made in accordance with national thread standards such as NPT, NPS, or their sub-types (MPT, FPT, etc.) Featuring a parallel or tapered thread, they are not compatible with British standards (such as BSPT or BSPP) that are more spread in Europe.
