Even a low-profile fall can ruin a poorly built tool, which can’t withstand colossal pressure and handling.

Coupler jaws

In the smooth process of lubrication and greasing, the Coupler jaws play a crucial role in holding the equipment and services in hard-to-reach areas. You have to ensure that the selected coupler can fit properly and is also locked to the gun’s tip strong enough.
