Designed for sanitary, hygienic, and other purposes, a boat plumbing system can be easier to install or repair than the pipelines found in most buildings. At least, the marine plumbing is not hidden inside solid walls, but still, it has its own nuances related to fittings, freshwater tank ventilation, a water pump and the pressure it creates, and so on. Meanwhile, boat nipples are often neglected and considered as something quite traditional, but still, it's recommended to pay some attention to them and choose only quality ones made of suitable materials. A wide assortment of such boat nipples is available on our virtual shelves.

We carry bronze, brass, nylon, and plastic fittings that comply with the highest standards. All of them feature reliable and corrosion-resistant construction, but some models are meant for hoses and have a barbed design, while others may feature different types of threads. It's crucial to choose the thread properly; aside from a diameter and male/female options, they can differ by their types (NPT, NPTF, etc.) Also, there are certain requirements for their location and safety; for instance, plastic plumbing fittings should never be used below the waterline.
