O-rings degrade over time from UV exposure, chemical contact, and repeated compression cycles, eventually allowing water to seep past joints and reduce system pressure. A fresh O-ring restores the factory seal. Prevent Slow Leaks and Pressure Loss Even a small leak at a filter joint drops internal pressure, reducing the flow of water through the media stages and lowering filtration efficiency. Because the O-ring sits out of sight, the only symptoms are often a damp area around the filter base or a gradual decline in water clarity. Inspecting and replacing O-rings during annual maintenance prevents these issues. Specification Details Compatible Models Biotec 12, 18, 24, 36; Biotec 18000, 32000 Material Rubber Type OEM replacement seal Installation Shut off the pump and drain the filter if necessary. Remove the old O-ring from its groove, clean any debris or mineral deposits, and seat the new ring evenly without twisting. Reassemble the joint hand-tight and restart the system to check for leaks. Ideal for seasonal maintenance on any large Biotec filter — keep a few spares in your maintenance kit.","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/oase-replacement-parts-default-title-oase-biotec-12-36-18000-32000-o-ring-43287411425599.webp?v=1790197186","href":"/product/oase-biotec-12-36-18000-32000-o-ring.html","buy_url":"https://xyjpsn-3p.myshopify.com/products/oase-biotec-12-36-18000-32000-o-ring","buy_url_source":"shops.shop_domain + product.handle","seller_name":"xyjpsn-3p.myshopify.com","seller_url":"https://xyjpsn-3p.myshopify.com/","return_policy_url":"https://xyjpsn-3p.myshopify.com/policies/refund-policy","media":[{"url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/oase-replacement-parts-default-title-oase-biotec-12-36-18000-32000-o-ring-43287411425599.webp?v=1790197186","alt":null,"position":0}],"related":[{"handle":"aquascape-smart-control-receiver-1","title":"AQUASCAPE SMART CONTROL RECEIVER","category":"Replacement Parts","price":"$138.31","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/aquascape_smart_controller_reciever_45038.jpg?v=1790199478","sku":"AQP-45038**DISC**","href":"/product/aquascape-smart-control-receiver-1.html"},{"handle":"oase-1-2-hp-floating-fountain-replacement-pump","title":"Oase 1/2 HP Floating Fountain - Replacement Pump","category":"Replacement Parts","price":"$285.59","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/oase_replacement_pump_with_75_ft_cord_for_.5_hp_floating_fountain_with_lights.jpg?v=1790198499","sku":"OASP-49522","href":"/product/oase-1-2-hp-floating-fountain-replacement-pump.html"},{"handle":"oase-24w-uvc-replacement-bulb-for-filtoclear-4000-g2-filtoclear-3400-g3-and-bitron-c-24","title":"OASE 24W UVC Replacement Bulb for Filtoclear 4000 (G2), Filtoclear 3400 (G3), and Bitron C 24","category":"Replacement Parts","price":"$60.89","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bitron_36w_uv_bulb_1_1.jpg?v=1790199589","sku":"OASP-41011","href":"/product/oase-24w-uvc-replacement-bulb-for-filtoclear-4000-g2-filtoclear-3400-g3-and-bitron-c-24.html"},{"handle":"oase-18w-uvc-replacement-bulb-for-vitronic-18-and-filtoclear-3000","title":"OASE 18W UVC Replacement Bulb for Vitronic 18 and FiltoClear 3000","category":"Replacement Parts","price":"$55.99","image_url":"https://cdn.shopify.com/s/files/1/1076/9324/4755/files/bitron_36w_uv_bulb_1.jpg?v=1790199593","sku":"OASP-40965","href":"/product/oase-18w-uvc-replacement-bulb-for-vitronic-18-and-filtoclear-3000.html"}]}}
