Parker’s NSL Series low-pressure, non-spill couplings provide an easy to-use, secure connection to transfer, fill and dispense Diesel Exhaust Fluid (DEF) from point of manufacture to bulk, point-of-use storage. DEF – a non-hazardous mixture of urea and deionized water – is used with the Selective Catalytic Reduction (SCR) system on diesel vehicles to reduce the emission of polluting nitrogen oxides (NOx).

Designed specifically to handle non-hazardous DEF, the couplings offer many advantages over competitive products. Plus the two-inch, male / female coupling set delivers a high flow rate of up to 100 gallons per minute, with excellent flow versus pressure drop characteristics to maintain optimum system integrity.
