About this part

This is a pack of two female and two male 4.0mm diameter gold plated "Super Bullet" high current inline connectors from ProTek R/C. The ProTek R/C "Super Bullet" Solid Gold Connectors are an absolute must for high current / high voltage applications! With lower resistance than a typical Dean's style ultra plug and traditional spring-type bullet connectors, they are the new standard for brushless motor applications. They can be used for battery connectors or motor to speed control connectors and are an ideal power connector for devices such as battery chargers, and power meters.

4mm Bullet Offerings:

  • PTK-5044: Low Profile (2 male)
  • PTK-5035: Standard (4 male)
  • PTK-5036: Standard (4 female)
  • PTK-5032: Standard (2 male / 2 female)

Excellent connectors! I’ve replaced all of my brushed motor connectors and DC power supply cable connectors with these. They solder easily and I appreciate the narrower profile allowing for smaller heat shrink and sleeving.

Easy to use and solder my wires. I would purchase again (probably will) when I have another project
