Guidi represents the pinnacle of bronze pipe fittings, strainers, intakes and more. These are Italian made products that offer zero-compromise solutions for your vessel. The 1164 series nickle plated bronze strainer is the right choice when there is a 90 degree angle water flow, from below to the side. The L configuration refers to the L shape path of the flow with one port on the side of the unit and another at the bottom. Strainers are installed to filter inlet water from impurities and bring clean water to heat exchangers, generators, and air conditioning systems. For nautical uses it is generally installed in the engine room.For replacement strainer baskets choose the correct size to match from the KIT1164 Strainer BasketsFor the replacement Cover O-Rings choose the correct size to match from KITORI1164For the replacement Covers choose the correct size to match from KIT1162DIFor the replacement Hold-Down Rings choose the correct size to match from KIT1162AN
