X-Pando
Their standard product is fine: https://www.xpando.com/xpando.php and it can be purchased on McMaster. Seals way better than Teflon at high temperatures

Heater cartridge
Standard E3D size, but needs to be at lleast 60 watts instead of 40. I have a heater block that can use a standard silicon nitride diesel heater plug at 100 watts or so, but some printer boards might not be able to supply that much power to a single heater, so proceed with caution and read up on the data sheets for your respective MOSFETs
