This is the threaded locking ring that secures the upper and lower tank halves on Sta-Rite System 2 Modular Media and Modular DE filters: it drops over the tank shell threads, rotates clockwise and clicks past the safety latch, sealing the tank so the filter can be opened for module cleaning and closed again with a positive lock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e🚩 PRO TIP:\u003c\/strong\u003e Never lubricate the Posi-Lok ring or the lower tank shell threads — lubricant collects grit and makes the ring hard to remove. Lubricate only the tank O-ring, clean both sealing surfaces, and rotate the ring clockwise until it clicks past the safety latch before pressurizing the filter.\u003c\/p\u003e\n\u003ch3\u003ePRODUCT FEATURES \u0026amp; SPECIFICATIONS:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Pentair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 27001-0054S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pool Filter Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart:\u003c\/strong\u003e Posi-Lok locking ring (tank closure ring)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Sta-Rite System 2 Modular Media filters PLM100, PLM125, PLM150, PLM175, PLM200 and PLM300; Sta-Rite System 2 Modular DE filters PLDE36, PLDE48, PLD50 and PLD70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Threaded ring locks the upper and lower filter tank halves together and clicks behind the tank safety latch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.45 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFREQUENTLY ASKED QUESTIONS:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhich filters does the Pentair Sta-Rite 27001-0054S Posi-Lok ring fit?\u003c\/strong\u003e The Pentair Sta-Rite 27001-0054S is the Posi-Lok locking ring for Sta-Rite System 2 Modular Media filters PLM100 through PLM300 and System 2 Modular DE filters PLDE36, PLDE48, PLD50 and PLD70.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMy System 2 filter leaks around the tank ring — is the 27001-0054S the fix?\u003c\/strong\u003e A leak at the Posi-Lok ring joint on a System 2 filter usually means the ring is not fully locked, the tank O-ring is worn, or the ring itself is cracked or thread-worn.
