The Edson Shatterproof Bronze Strainer is used to prevent clogging of a suction hose, pipe and pump. The resilience, corrosive resistance and non-sparking character of marine grade bronze will provide extended life over aluminum, cast steel or plastic strainers. This Edson strainer has 2" FNPT (Female National Pipe Threads) for easy attachment to hose or pipe fittings ending with 2" MNPT (Male National Pipe Threads).
