The Multiquip SP3015 Extra Heavy Nipple is a genuine OEM component designed for STOW diaphragm pump models SDP-3, SDP-2, and CA90749. As an authentic Multiquip OEM part, the SP3015 is manufactured to the exact specifications of the original, ensuring a direct, trouble-free installation with no modifications to your pump assembly. This nipple is purpose-built for the demanding fluid-transfer conditions these diaphragm pumps operate in, delivering the wall thickness and material integrity the heavy-duty designation requires. Confirm your model against the listed fitment codes before ordering to ensure an exact match.
Key Features
- Heavy-Wall Construction: — The extra-heavy profile provides greater wall thickness than standard nipples, standing up to the pressure cycling and abrasion common in diaphragm pump applications.
- Genuine OEM Specification: — Manufactured to Multiquip's original material and dimensional standards, so thread engagement and seating match the pump's ported fittings exactly as designed.
- Direct Replacement: — The SP3015 threads directly into the existing port without reworking fittings or adapters, keeping installation straightforward on SDP-3, SDP-2, and CA90749 models.
- Confirmed Fitment: — Verified for STOW diaphragm pump models SDP-3, SDP-2, and CA90749 — reference your pump's model code before ordering.
- Leak-Free Flow Path: — A correctly fitted, heavy-duty nipple maintains a sealed fluid path through the pump, preventing pressure loss and protecting downstream hose connections from the stress of a weeping joint.
- Fluid System Integrity: — Using an OEM-grade nipple rated for the application helps prevent connection failures that can compromise pump output or allow fluid to escape at the fitting.
A nipple fitting serves as a threaded connector in a pump's fluid circuit, linking ported housings, hoses, or manifold connections into a continuous sealed flow path. In a diaphragm pump, these fittings are subject to repeated pressure pulses with every stroke cycle, making wall thickness and thread quality critical — a standard or undersized nipple can fatigue, leak, or crack under those cyclic loads. When a nipple fails, it breaks the sealed circuit, resulting in fluid loss, drop in discharge pressure, and potential damage to surrounding hose ends or gasket faces.
