Pressure Washer Unloaders

Shop pressure washer unloaders and bypass accessories, including General Pump Pulsar and ZK1 flow-sensitive models, VRT unloaders and blue-spring options. Open each listing to compare its flow range, pressure rating, temperature limit and port connections.

An unloader must match the pump and the complete system. Thread standards matter: the Pulsar PLSRZ2140 has 1/2-inch BSP female ports, while other models use different connections. Confirm your exact model and plumbing before ordering.
