Pentair Sta-Rite Posi-Lok Ring for System 2 Modular Filters 27001-0054S
Pentair Sta-Rite Posi-Lok Ring for System 2 Modular Filters 27001-0054S
Replace a cracked, worn or hard-to-turn tank locking ring with the genuine Pentair Sta-Rite 27001-0054S Posi-Lok ring. 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.
🚩 PRO TIP: 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.

FREQUENTLY ASKED QUESTIONS:
- Which filters does the Pentair Sta-Rite 27001-0054S Posi-Lok ring fit? 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.
- My System 2 filter leaks around the tank ring — is the 27001-0054S the fix? 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. The Pentair Sta-Rite 27001-0054S replaces the ring; check and lubricate the tank O-ring at the same time.
- Does the 27001-0054S include the safety latch? No — the 27001-0054S is the Posi-Lok ring only. The safety latch for the ring is a separate part, 27001-0051Z.
- How does the Posi-Lok ring lock? Set the Pentair Sta-Rite 27001-0054S squarely over the tank shell threads, rotate it counterclockwise until it drops into the slots, then rotate clockwise until it clicks securely behind the safety latch.
