The Multiquip 1391100090B Delivery Elbow NPT 3" is a genuine OEM component designed for QP303H and QP303B centrifugal pumps. As a factory-sourced replacement, this elbow meets the original engineering specifications for the pump's discharge assembly, ensuring a proper pressure-rated connection at the outlet port. This part is confirmed to fit QP303H and QP303B series centrifugal pumps, so verify your model before ordering. Sourcing the correct OEM delivery elbow matters — an ill-fitting or undersized elbow at the discharge point can compromise flow efficiency and create leak points under working pressure.
Key Features
- Genuine OEM Casting and Thread Spec — Manufactured to the original 3" NPT thread specification, ensuring a leak-free, pressure-rated connection at the pump discharge without thread mismatch or sealant workarounds.
- Direct Discharge Port Fit — Engineered to connect directly to the pump outlet housing on QP303H and QP303B models, matching the original elbow geometry and bolt pattern.
- Confirmed Fitment for QP303H and QP303B — Verified for Multiquip QP303H and QP303B centrifugal pump models; always cross-reference your model and serial plate before ordering.
- Maintains Full Flow Capacity — A correctly fitted delivery elbow preserves the pump's rated discharge performance; a cracked or corroded elbow reduces pressure and flow at the outlet, cutting productivity on dewatering and transfer jobs.
- Pressure-System Safety — On a working pump discharge line, a properly threaded and seated elbow prevents high-pressure blowouts at the outlet connection — a genuine OEM part eliminates the risk of an underrated substitute failing under load.
The delivery elbow is the threaded fitting at the pump's discharge outlet that directs pressurized water flow out of the pump body and into the connected hose or pipe run. On centrifugal pumps like the QP303 series, the discharge elbow must maintain a reliable, pressure-tight seal at the 3" NPT connection to sustain full flow output without leakage. When this elbow cracks, corrodes, or strips its threads, the pump loses discharge pressure and the connection becomes a leak point — replacing it with the correct OEM part restores full operational output and keeps the discharge line secure under load.
