Why Choose the Partex RR43 4 mm Red Ring Crimp (Pack of 100)?
The Partex RR43 red ring crimp terminal is designed for secure termination of 0.5 to 1.5 mm² stranded copper conductors, making it suitable for light-duty control and signal wiring. With a 4 mm ring compatible with M4 studs, it provides reliable mechanical retention and consistent electrical performance in compact installations.
Each terminal incorporates a tin-plated high-conductivity copper barrel to minimise contact resistance and resist corrosion, along with a pre-insulated red PVC sleeve for clear conductor size identification and improved safety. Supplied in a pack of 100, the RR43 is ideal for panel builders, automotive technicians and maintenance engineers requiring dependable, repeatable crimps.
