Constructed from durable rubber, this O-ring provides resistance to wear and chemical exposure in aquatic environments. Measuring 2.25 inches in length, 2.25 inches in width, and 0.25 inches in height, it is sized for the 2-inch bulkhead fitting on FNS Plus filter assemblies. Pool service technicians and plumbers install this part as a direct OEM-style replacement to restore a proper watertight seal at the outlet pipe connection.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in residential and commercial pool and spa installations where Pentair FNS Plus D.E. filters are installed. It seats at the 2-inch bulkhead outlet pipe location and is a common service item during filter teardowns, annual maintenance, and leak diagnosis. It is also noted as compatible with Titan and Titan CM applications (O-24 designation). Replacing a worn or cracked O-ring at this location restores proper system pressure and prevents water loss at the filter housing outlet.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-137 O-ring cross-section sized for the 2-inch bulkhead outlet pipe on FNS Plus D.E. filters\u003c\/li\u003e\n\u003cli\u003eRubber construction provides durability and resistance to pool chemicals and wear\u003c\/li\u003e\n\u003cli\u003eDimensions: 2.25 inches length by 2.25 inches width by 0.25 inches height\u003c\/li\u003e\n\u003cli\u003eDirect OEM-style replacement for maintaining a watertight seal at the filter outlet\u003c\/li\u003e\n\u003cli\u003eCompatible with Titan and Titan CM (O-24) applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFits Pentair FNS Plus Pool and Spa D.E.

Before replacing the O-ring, shut off the pump and relieve system pressure by opening the air relief valve on the filter. Inspect the O-ring groove for debris or damage before seating the new O-ring. Applying a thin coat of O-ring-compatible silicone lubricant helps achieve a proper seal and extends service life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Size\u003c\/strong\u003e: 2-137\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulkhead Size\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Outlet pipe bulkhead seal, FNS Plus D.E. filter\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: 59000600z\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENTAIR","offers":[{"title":"Default Title","offer_id":51138714927410,"sku":"59000600Z","price":22.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305531541.jpg?v=1778262320","url":"https:\/\/voomisupply.com\/products\/pentair-59000600z-bulkhead-o-ring-fns-plus-de-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
