Its durable, chemical-resistant elastomer maintains flexibility under pressure, preventing leaks around the mid-clamp or lid band that can reduce operating efficiency. Molded to match the common sealing dimensions used across many sand and cartridge filter designs, the O-87 seats smoothly into the tank groove for secure closure during regular service. By maintaining a stable internal seal, it supports reliable pressure retention and dependable filtration performance throughout daily operation.\u003c\/p\u003e\n\u003ch3 data-start=\"968\" data-end=\"986\"\u003e\u003cstrong data-start=\"972\" data-end=\"986\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"987\" data-end=\"1700\"\u003e\n\u003cli data-start=\"987\" data-end=\"1133\"\u003e\n\u003cp data-start=\"989\" data-end=\"1133\"\u003e\u003cstrong data-start=\"989\" data-end=\"1015\"\u003eUniversal 18 Inch Fit:\u003c\/strong\u003e Sized to align with widely used sealing grooves on 18 inch sand and cartridge filter tanks for broad compatibility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1134\" data-end=\"1289\"\u003e\n\u003cp data-start=\"1136\" data-end=\"1289\"\u003e\u003cstrong data-start=\"1136\" data-end=\"1171\"\u003ePrevents Water \u0026amp; Pressure Loss:\u003c\/strong\u003e Forms a tight seal at the clamp or lid connection, reducing seepage and helping maintain proper operating pressure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1290\" data-end=\"1438\"\u003e\n\u003cp data-start=\"1292\" data-end=\"1438\"\u003e\u003cstrong data-start=\"1292\" data-end=\"1320\"\u003eDurable Elastomer Build:\u003c\/strong\u003e Chemical-resistant material withstands chlorine, heat, and outdoor elements without losing strength or flexibility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1439\" data-end=\"1571\"\u003e\n\u003cp data-start=\"1441\" data-end=\"1571\"\u003e\u003cstrong data-start=\"1441\" data-end=\"1463\"\u003ePrecision Seating:\u003c\/strong\u003e Molded for smooth placement inside the tank channel, promoting uniform sealing during maintenance cycles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1572\" data-end=\"1700\"\u003e\n\u003cp data-start=\"1574\" data-end=\"1700\"\u003e\u003cstrong data-start=\"1574\" data-end=\"1605\"\u003eEnhances Filtration Output:\u003c\/strong\u003e Helps stabilize system pressure to support consistent sand or cartridge filtration efficiency.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"3297\" data-end=\"3316\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"3317\" data-end=\"3716\"\u003eThe Aladdin O-87 Universal 18-inch Filter Tank O-Ring replaces the sealing gasket used on many 18\" sand and cartridge filters.
