The PRO-LUBE SWV/DP/3-4/N is a coupler adapter fitting used to connect or transition between fluid-handling components in plumbing, HVAC, or industrial lubrication systems. This type of fitting provides a secure mechanical connection point where two lines, hoses, or components must be joined or adapted to different port sizes or thread types. It is a compact, single-piece hardware item intended for installation by licensed plumbers, HVAC technicians, or mechanical contractors working on fluid or lubricant distribution systems.
Coupler adapters of this type are commonly used in residential and light commercial service applications. Typical installations include hydraulic lines, lubrication circuits, compressed air systems, and general fluid transfer plumbing where a transition fitting is required. The part ships as a single unit and is suited for bench stock or single-point repair use.
Designed as a direct-replacement coupler adapter fitting for fluid handling and lubrication system applications where this part number is specified.
Installation should be performed by a qualified technician familiar with fluid or pneumatic system service. Always depressurize and isolate the system before removing or installing any coupler or adapter fitting. Inspect mating threads and sealing surfaces prior to assembly. Verify that the fitting is rated for the operating pressure and fluid type of the target system before placing into service.
