Brass Hydraulic Hose Fitting

The SPEEDAIRE 6X423 is a brass hydraulic hose fitting designed for secure fluid connections in air compressor and vacuum pump systems. It suits maintenance technicians and system builders who need a reliable straight-form joint for hose routing.

Temperature rating and pressure capacity

Rated for a maximum working pressure of 250 psi at 70 degrees Fahrenheit, the brass construction provides corrosion resistance during normal operation. The reusable design allows the fitting to be removed and reinstalled without compromising the seal.

Hose Barb x NPT connection

The dual Hose Barb x NPT interface fits hose with a dash size of -4, an inner diameter of 1/4 inch and an outer diameter of 1/2 inch. This straight fitting joins hose routes directly, freeing up space that angled adapters would occupy.

Questions about this item

How do I install the SPEEDAIRE 6X423 brass fitting onto a 1/4 inch ID hose and what step causes leaks?

Push the hose fully over the -4 barb until it seats against the body, then secure with a clamp; the common error is skipping the clamp or not pushing the hose past the last barb ridge.

What maintenance will the brass hose barb and NPT threads need over time?

Inspect the barb for corrosion or hose cracking at each oil change; reapply thread sealant on the 1/4 NPT male threads if the joint is broken and remade.

At what pressure limit should I stop running the fitting during continuous operation?

Do not exceed 250 psi at 70 F; sustained pressure above that rating is the first limit that can cause fitting failure or hose blow-off.
