Refrigerant Charging Hose 1/4 to 5/16 SAE

This 4.92Ft blue hose connects 1/4 SAE and 5/16 SAE threads for air-conditioning and refrigeration service. It is built for technicians and DIY users who need a reliable line for charging, testing or evacuating residential and light-commercial systems. The rubber tube and brass fittings suit common refrigerants used in HVAC and mini-split maintenance. Buyers who require metric threads or longer reach will need a different hose.

Pressure Rating and Build Quality

The hose handles an 800PSI working pressure with a 4000PSI burst margin, so normal charging and recovery cycles stay well within its limits. A six-sided crimp locks the brass connector to the rubber, preventing blow-off even at maximum pressure. The 45° bend on one end eases access to tight service ports without kinking the line. No noise or thermal data apply to this passive component.

Thread Compatibility Decides Fit

The single specification that determines whether this part works for you is the paired thread size: one end is 1/4 SAE, the other is 5/16 SAE. Both must match the ports on your gauge set, vacuum pump or recovery unit. If your equipment uses a different flare standard or thread pitch, this hose will not connect.

Questions about this item

How do I install the 45-degree bent end on a 1/4 SAE service port without cross-threading the brass fitting?

Finger-tighten the knurled 1/4 SAE coupler until the flare seats, then give a light 1/6-turn with a wrench; the 45° bend clears tight panels so you can see the threads engage.

When should I replace this 4.92 ft charging hose if the rubber cover shows surface cracking?

Replace it immediately once cover cracks appear or the hose feels stiff; the rubber-to-brass crimp is not field-serviceable and a 4000 PSI burst rating only applies to an intact hose.

At what sustained pressure will the 800 PSI working limit be reached first during a long vacuum pull on a mini-split system?

The 800 PSI working pressure is the design ceiling; continuous operation near that level — such as deep evacuation with a high-capacity pump — will hit the limit before the 4000 PSI burst rating becomes relevant.
