#12 To #4 Union Adapter

The AEROQUIP #12 To #4 Union Adapter is a precision hydraulic fitting designed to connect two different port sizes in hydraulic systems. This adapter is ideal for a variety of applications, including automotive, industrial, and other hydraulic systems where reliable connections are essential. It allows for seamless integration of components that do not share standard port sizes.

Constructed with a proven swaged design, this union adapter creates a permanent, leak-free connection without the need for additional fasteners or complex assembly procedures. The precision machining ensures consistent flow characteristics across the size transition, which is critical for maintaining proper pressure distribution in hydraulic systems. This design helps to protect downstream components from potential damage.

Technicians and engineers working with custom hydraulic solutions will find this adapter invaluable for ensuring compatibility between different port sizes. Its compact footprint allows for flexible installation in tight spaces, making it a practical choice for various setups, including cooling circuits and hydraulic brake lines.
