Eaton AEROQUIP FJ3012-02-1010S female low side hose fitting dash 10 body repair tool

Automotive AC Hose Fitting

This Eaton Aeroquip female low-side hose fitting connects to a vehicle air-conditioning system using a 7/8-14 thread and dash-10 sizing. It accepts refrigerant types 134A, R12, R22, R502, MP39, MP66 and R404A for service work on compatible systems. The steel body is rated for a maximum working pressure of 500 PSI and a minimum burst pressure of 2000 PSI. It is designed for use with a female O-ring and low-side service port.

Build Integration Requirements

The fitting requires a hose with an outside diameter of 0.78 inches and an inside diameter of 0.5 inches for proper assembly. Its SAE J2064 compliance ensures it meets the dimensional and performance standards for automotive refrigerant connections. Installers must verify that the existing low-side port matches the 7/8-14 female thread before installation. No additional adapters are included, so the surrounding hose and port must align with these specifications.

Pressure Performance and Durability

In normal service the steel construction withstands continuous operating pressures up to 500 PSI with a safety margin to 2000 PSI burst. The material resists deformation under repeated pressurisation cycles common in AC system operation. Because the fitting is a passive metal component, it generates no noise and draws no power during use. Thermal behaviour follows the refrigerant temperature range of the connected system without additional cooling requirements.
