An incorrectly sized, damaged, hardened, or missing O-ring can allow lubricant to escape or moisture to enter the hub.\u003c\/p\u003e\n\u003cp\u003eLoss of lubricant or contamination may contribute to premature bearing wear, corrosion, overheating, or hub failure. Maintaining the correct O-ring seal is therefore an important part of servicing oil-lubricated boat trailer hubs.\u003c\/p\u003e\n\u003ch3\u003eWhen Should the O-Ring Be Replaced?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWhen the existing O-ring is cut, cracked, flattened, hardened, or visibly damaged.\u003c\/li\u003e\n\u003cli\u003eWhen oil seepage is observed around the hub cap sealing joint.\u003c\/li\u003e\n\u003cli\u003eWhen the O-ring has become stretched or no longer fits correctly in its intended sealing position.\u003c\/li\u003e\n\u003cli\u003eWhen the hub cap is removed and the seal cannot be confidently reused according to the manufacturer's service instructions.\u003c\/li\u003e\n\u003cli\u003eDuring hub maintenance when inspection indicates deterioration of the existing seal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #cbd5dc; margin: 12px 0 20px 0; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth colspan=\"2\" style=\"background-color: #12344d; color: #ffffff; text-align: left; padding: 12px; border: 1px solid #cbd5dc; font-weight: bold;\"\u003eProduct Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; width: 38%; font-weight: bold;\"\u003eManufacturer \/ Brand\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eEZ Loader\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003ePart Number \/ MPN\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003e250-034393\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003ePart Type\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eOil Bath Hub Cap O-Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eHub Configuration\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003e6-Lug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eLubrication System\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eOil Bath\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003ePrimary Function\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eHelps seal the oil hub cap and retain lubricant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eCompatible EZ Loader 6-Lug Oil Bath Hub Caps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eNot Compatible With\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003e5-Lug Oil Bath Hub Caps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color: #f8fbfc; border: 1px solid #cbd5dc; padding: 9px; font-weight: bold;\"\u003eFitment Verification\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #cbd5dc; padding: 9px;\"\u003eConfirm Hub Cap Design, Lug Configuration \u0026amp; Original O-Ring Specifications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eInstallation and Maintenance Recommendations\u003c\/h3\u003e\n\u003cp\u003eBefore installing the replacement O-ring, inspect the hub cap, sealing groove, and mating surface for damage, corrosion, dirt, or old sealing material.
