The Multiquip 0790434040 Nipple NPS4 NPT4 is a genuine OEM fitting designed for QP402H and QP402B centrifugal pumps. As an authorized Multiquip OEM component, this nipple is manufactured to the exact thread specifications required for a secure, leak-free installation on these pump models. It is a direct-fit replacement that slots into the existing plumbing configuration without rework or adapters. Whether you are servicing a QP402H or QP402B unit in the field or completing a scheduled maintenance rebuild, part number 0790434040 ensures the connection point performs exactly as intended.
Key Features
- Genuine OEM Thread Spec: — Manufactured to precise NPS4 and NPT4 thread standards, ensuring a pressure-rated, leak-free seal on every installation.
- Direct-Fit Replacement: — Matches the original plumbing interface on QP402H and QP402B centrifugal pumps, threading in cleanly without modification to existing fittings or housings.
- Confirmed Fitment: — Verified for use on QP402H and QP402B Multiquip centrifugal dewatering pumps.
- Maintains Flow Integrity: — A correctly fitted nipple keeps discharge and suction lines fully sealed under pump operating pressure, preventing flow loss and protecting pump efficiency.
- Authorized Multiquip OEM Part: — Sourced directly through the Multiquip OEM supply chain, so you receive the same component installed at the factory.
A pipe nipple is a short threaded fitting used to connect two sections of plumbing or to join a pump port to a hose, pipe, or manifold. On centrifugal pumps like the QP402H and QP402B, the nipple plays a critical role in maintaining a pressure-tight seal at the pump's discharge or suction connection point. If the nipple is damaged, cross-threaded, or corroded, it can cause leaks that reduce pump output, allow air ingestion on the suction side, or create hazardous conditions around the work area. Replacing a worn nipple with the correct OEM part restores the integrity of the fluid path and keeps the pump operating at rated capacity.
