The non-petroleum-distillate chemistry is compatible with conventional and synthetic lubricants, automatic transmission fluid, power steering fluid, gear oil and hydraulic oil. It works by conditioning and softening rubber rather than adding bulk, helping you avoid over-swelling while protecting bearings and internal parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does AT-205 stop leaks without damaging internal parts?\u003c\/h3\u003e\n\u003cp\u003eAT-205 uses a seal-conditioning formula that penetrates and rejuvenates rubber and elastomer materials instead of dissolving or breaking them down. Because it contains no petroleum distillates, it won’t degrade seals or create harmful residues within the lubrication circuit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConditions rubber to restore flexibility and shape\u003c\/li\u003e\n  \u003cli\u003eNon-petroleum base avoids harmful residues\u003c\/li\u003e\n  \u003cli\u003eSafe for metal bearings and internal components\u003c\/li\u003e\n  \u003cli\u003eWorks with a wide range of lubricants and fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen should I use this 8-ounce bottle of AT-205?\u003c\/h3\u003e\n\u003cp\u003eUse the 8 oz bottle for light to moderate leaks, spot treatments, or as a trial before treating an entire system.

AT-205 Re-Seal 8 oz is aimed at DIY mechanics, professional service shops, and fleet managers who need a targeted, reliable remedy for rubber-seal leaks without replacing parts immediately. It’s especially useful for older vehicles, equipment with aged seals, and anyone wanting a fast, low-cost alternative to disassembly or expensive repairs. Keep an 8-ounce bottle on hand for spot fixes or as a first-line treatment to extend the service life of seals and gaskets while protecting internal components.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is AT-205 safe with synthetic oils and ATF?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
