Here you will find replacement regulators for compressed air systems. When choosing a replacement regulator you want to keep in mind the desired output pressure you need for your specific marker. Most markers work best with a high pressure regulator setup but some may perform better with a low pressure regulator setup. An example of a marker that functions better with a low pressure regulator would be a Bob Long G6R. The marker will work with either a HP or LP regulator but it is suggested to use a LP output to maximize performance. The SLP Ninja regulator is highly recommended for all markers that suggest the use of LP regulators (300 psi output standard).
