FlareSeal's multi-ring copper gasket with a full-thread-lock coating is designed to address surface scratches, small misalignments, and leaking Schrader cores by providing an easy clip-on seal that works on new and existing connections. This 10-pack of 1\/4\" gaskets fits standard SAE 45° flare fittings and is optimized for quick, dependable service on pilot lines, thermostatic expansion valves, filter driers, and more.\u003c\/p\u003e\n\n\u003ch3\u003eHow does FlareSeal stop leaks on a 1\/4\" flare connection?\u003c\/h3\u003e\n\u003cp\u003eThe gasket uses a multi-ring flare surface that creates multiple crush points for sealing, while the thread-lock coating increases friction and fills minor surface defects. It clips onto the male flare so you can assemble the fitting normally; when tightened, the rings compress to form the seal without needing extra torque or adhesives.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMulti-ring copper face provides several contact bands for a consistent crush seal.\u003c\/li\u003e\n  \u003cli\u003eFull copper base metal conforms to flare imperfections and scratches.\u003c\/li\u003e\n  \u003cli\u003eThread-lock coating prevents vibration loosening and improves immediate sealing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan FlareSeal be used on existing leaking fittings and Schrader valves?\u003c\/h3\u003e\n\u003cp\u003eYes — FlareSeal is designed to clip onto existing male flares and stop leaks without disassembling the entire line.
