A failed or stripped band nut compromises the integrity of the tank band clamp, which can result in filter body separation under operating pressure.\u003c\/p\u003e\n\n\u003ch3\u003ePoolaroo Pro Tip\u003c\/h3\u003e\n\u003cp\u003eWhen replacing this nut, inspect the full band assembly — the bolt, nut, and band itself — for corrosion or wear before reassembling. Brass hardware in wet pool environments is susceptible to galvanic corrosion when in contact with dissimilar metals. Torque the nut evenly and do not overtighten; overtightening can crack the filter tank flange. Confirm your specific filter model number (found on the filter tank label) before ordering to ensure this nut matches your band assembly hardware configuration.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52770074984723,"sku":"194997Z","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-nut-for-band-assembly-for-fsh-fns-and-quad-filters-194997z-1.png?v=1766600287","url":"https:\/\/poolaroo.com\/products\/pentair-nut-band-fsh-fns-quad-filters-194997z","provider":"Poolaroo","version":"1.0","type":"link"}
