Use a silicone-based lubricant such as the \u003ca href=\"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_r172351\" alt=\"Pentair R172351 Lifeguard Silicone Lubricant\"\u003ePentair R172351 Lifeguard Silicone Lubricant\u003c\/a\u003e to condition the O-ring before seating it. Do not use petroleum-based products, as these will degrade the O-ring and cause premature failure. Hand-tighten the bulkhead nut only — over-tightening can crack the fitting or the filter tank wall.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52770058895635,"sku":"190141","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-bulkhead-fitting-fns-nautilus-plus-2-inch-o-ring-190141-5.webp?v=1767401065","url":"https:\/\/poolaroo.com\/products\/pentair-bulkhead-fitting-fns-nautilus-plus-2-w-o-ring-190141","provider":"Poolaroo","version":"1.0","type":"link"}
