Parker Hannifin Corporation introduces the NSL Series of two-inch flow size stainless steel couplings that are non-spill and high-flow.

The Parker NSL Series provides an easy-to-use, secure connection to transfer, fill, and dispense Diesel Exhaust Fluid (DEF) and other chemicals 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 (NO_x).

The couplings also offer: a two-inch male / female coupling set that delivers a high flow rate of up to 100 gallons per minute, with excellent flow versus pressure drop characteristics to maintain optimum system integrity; port configurations to accommodate standard tank and hose fittings; non-spill valving with near-zero spillage and air inclusion; an easy-to-use, familiar quick connect operation; and a stainless steel construction that offers chemical compatibility and enhanced durability.

Parker’s NSL Series is designed for use by manufacturers of DEF pumping and storage systems; DEF manufacturers; and personnel responsible for maintenance and refueling of diesel vehicles, particularly as it concerns DEF and the SCR system.
