The following vendor has Very Difficult to Find OEM style Bullet/Snap connectors that require a double crimp and are supplied with water resistant insulators. I recently purchased 25 each of the SB1, SS1 & DS1.
You must have the proper crimping tool to make the terminations with the insulator and the conductor to use this style connector.
Price for std pkg of 25 was $3.49 for the SB1 & SS1
