Referenced under O-337, this O-ring provides a pressure-rated seal at key connection points within a filter assembly, preventing water bypass and maintaining system integrity. Pool service technicians and equipment installers use this part during routine maintenance, filter teardowns, and tank reseals. Selecting the correct O-ring size and profile is critical to maintaining leak-free operation in any pressurized filtration system.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in pool and spa filtration systems where a 16-inch sealing diameter is required. It is a direct-fit replacement component intended for PacFab and Pentair filter equipment. Typical applications include seasonal filter openings, post-backwash inspections, and any service call where the filter tank is disassembled and the seal shows wear, cracking, or deformation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e16-inch O-ring profile for a precise, leak-free seal on compatible filter tanks\u003c\/li\u003e\n\u003cli\u003eCross-referenced as O-337 for service lookup and parts identification\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement designed for Pentair and PacFab filtration equipment\u003c\/li\u003e\n\u003cli\u003eRestores proper sealing performance in pressurized pool filter assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement O-ring for Pentair and PacFab pool filter equipment requiring a 16-inch O-ring, cross-referenced as O-337.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pool service technician. Shut off the circulation pump and relieve all system pressure before disassembling the filter tank. Clean the O-ring groove thoroughly and apply an O-ring-compatible lubricant before seating the new seal. Do not use petroleum-based lubricants, as they will degrade the O-ring material over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Size\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference\u003c\/strong\u003e: O-337\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PENTAIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 152235\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENTAIR","offers":[{"title":"Default Title","offer_id":68093058482482,"sku":"152235","price":19.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4642f410bb3d0085382fa7a26294948.jpg?v=1793231573","url":"https:\/\/voomisupply.com\/products\/pentair-152235-o-ring-16-inch-pool-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
