{"product_id":"sunsun-cpf-pressure-filter-clamping-ring-replacement","title":"Sunsun CPF Clamping Ring – Replacement Part for CPF-20000 \/ CPF-30000 \/ CPF-50000","description":"\u003cp dir=\"ltr\"\u003eThis is the original Sunsun clamping ring for CPF-series pond bio pressure filters — compatible with the CPF-20000, CPF-30000, and CPF-50000 models. The clamping ring is what locks the filter's top cover to the body and holds the pressure seal in place; if it's cracked, loose, or won't latch tight anymore, water will leak from the seam even with a good cover fitted. This genuine OEM replacement restores a secure, leak-free lock without replacing the whole filter.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eStocked and shipped by Koi Water Hyderabad — trusted by koi keepers and pond builders across India for genuine Sunsun spares.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhy You Need This Replacement Clamping Ring\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores the Pressure Lock\u003c\/strong\u003e — A worn or cracked ring can't hold the cover tight, causing leaks even with a good cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOriginal Fit Guaranteed\u003c\/strong\u003e — Manufactured to SunSun's exact specifications for a secure, snap-tight lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrevents Cover Damage\u003c\/strong\u003e — A loose ring puts uneven stress on the cover, which can crack it over time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Swap\u003c\/strong\u003e — No tools needed; unclip the old ring and snap the new one into place\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis clamping ring fits the following Sunsun Pond Bio Pressure Filter models:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eSunsun CPF-20000\u003c\/li\u003e\n\u003cli\u003eSunsun CPF-30000\u003c\/li\u003e\n\u003cli\u003eSunsun CPF-50000\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cem\u003ePlease check your filter's model number (printed on the unit body) before ordering, as clamping rings are sized specifically per model and are not interchangeable across sizes.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhen Should You Replace This Part?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eRing won't snap or latch fully closed\u003c\/li\u003e\n\u003cli\u003eWater seeping from the seam between cover and body even after tightening\u003c\/li\u003e\n\u003cli\u003eVisible cracks, warping, or brittleness in the ring\u003c\/li\u003e\n\u003cli\u003eCover feels loose or wobbles even when the ring is engaged\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eAttribute\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSunsun\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Type\u003c\/td\u003e\n\u003ctd\u003eClamping Ring — Bio Pressure Filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Models\u003c\/td\u003e\n\u003ctd\u003eCPF-20000, CPF-30000, CPF-50000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-grade UV-resistant plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuthenticity\u003c\/td\u003e\n\u003ctd\u003eOriginal SunSun OEM part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eDirect fit, no modification required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch3 dir=\"ltr\"\u003eFAQs\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eQ1: Will this ring fit my CPF-30000 exactly?\u003c\/strong\u003e\u003cbr\u003eYes, this ring is sized specifically for the CPF-30000 (and separately for CPF-20000\/CPF-50000 — confirm your model before ordering, as sizes are not interchangeable).\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eQ2: My filter is leaking even though the cover looks fine — is this the fix?\u003c\/strong\u003e\u003cbr\u003eMost likely, yes.
