Review on ArmorBlue Poly Dispense Coupler With ¾” Barb For Diesel Exhaust Fluid (DEF) Dispenser Rates Up To 23 Gallons Per Minute Audible Click Latch Feature 4-Pin DEF Coupler by Kyle Ahmed

I never thought I'd be so enamored with a coupler, but this ArmorBlue Poly Dispense Coupler had me at "audible click latch feature." Seriously, my inner child giggled with delight every time I attached it to my DEF dispenser. And the fact that it can pump up to 23 GPM? Pure magic. Plus, the 4-pin design makes it super easy to use with my existing setup. Overall, I'm in love with this coupler and would recommend it to anyone looking for a DEF dispenser upgrade.
