TO-3P Silicone Rubber Insulating Kit – Pack of 4 (JAYCAR)

TO-3P package needs its own insulator shape, and this kit has it. Four silicone rubber washers, pre-cut for the TO-3P footprint. No scraping mica, no spreading grease, no "will this actually fit" moment mid-solder. Fit the washer, seat the transistor, tighten the screw. Isolated, thermally coupled, done. Pack of 4 means you've got spares for the next build without a separate order
