The Multiquip SP3041 Extra Heavy Nipple is a genuine OEM replacement designed for STOW Diaphragm Pump models SDP-3, SDP-2, and CA90749. Built to the same specification as the original component, this nipple delivers the wall thickness and thread integrity needed to maintain leak-free fluid connections under the demanding pressures of diaphragm pump operation. Sourced directly through Multiquip's OEM parts program, the SP3041 is the correct, authorized replacement for these pump models.
Key Features
- Extra Heavy Wall Construction — Heavier wall thickness compared to standard nipples provides greater resistance to pressure surges and mechanical stress in diaphragm pump fluid lines.
- Genuine OEM Quality — Manufactured to Multiquip's original material and thread specification, ensuring consistent sealing performance without improvised fitment workarounds.
- Direct Replacement for STOW Diaphragm Pumps — Fits SDP-3, SDP-2, and CA90749 models with correct thread dimensions and connection geometry for straightforward installation.
- Maintains Fluid Line Integrity — A properly functioning nipple keeps pump discharge and suction circuits fully sealed; a cracked or undersized nipple invites leaks that compromise flow output and pump priming.
- Pressure-Rated Fluid Handling — The extra heavy designation ensures this fitting meets the pressure demands of continuous diaphragm pump service, where standard-weight fittings may fail prematurely.
A pipe nipple is a short threaded fitting used to connect sections of pipe or attach hose and valve assemblies within a pump's fluid circuit. In diaphragm pump applications, nipples carry the full pressure generated by the pump's stroke cycle, making wall thickness and thread quality critical to long-term sealing. When a nipple cracks, strips, or corrodes, it creates leaks that reduce pumping efficiency, introduce air into the suction line, and can shut down operations entirely until the fitting is replaced.
