Built from corrosion-resistant stainless steel, the Pentair FNS Plus Filter Wing Nut threads directly onto the tie rod inside your Pentair FNS Plus DE Filter Tank. When an existing wing nut becomes stripped or weakened, this factory-grade replacement restores a firm, leak-free hold that keeps every filter grid locked in position for maximum water clarity.
