Multiquip 3053041 Suction and Discharge Nipple

The Multiquip 3053041 Suction and Discharge Nipple is a genuine OEM component designed for MQ diaphragm pump models D306, MQ-D306HA, and MQ-D305. Sourced directly from Multiquip, this nipple meets the exact dimensional and material standards required for proper fluid transfer performance on these pumps. It is a direct-fit replacement that installs to the same port connections as the original, ensuring a secure, leak-free seal on both the suction and discharge sides. If you are servicing any of the supported MQ diaphragm pump models, verifying part number 3053041 against your machine's parts manual is the best way to confirm correct fitment before ordering.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for consistent port sealing and fluid flow integrity on diaphragm pumps.
• Dual-Function Port Fitting — Serves both the suction and discharge connections, maintaining balanced flow through the pump's inlet and outlet circuit.
• Direct-Fit Replacement — Engineered to match the original port thread pattern and geometry, allowing straightforward installation on D306, MQ-D306HA, and MQ-D305 pumps without additional machining or adaptation.
• Protects Pump Flow Performance — A damaged or corroded nipple can cause pressure loss, cavitation, or fluid bypass; replacing it restores full suction lift and discharge output to specification.
• Verified Multiquip Part Number — Part number this part is the OEM-assigned reference for this fitting, giving you confidence you are ordering the correct component for your pump model.

The suction and discharge nipple is the threaded fitting that connects the pump's internal fluid passages to the external suction and discharge hose or pipe assemblies. On a diaphragm pump, it plays a critical role in maintaining an airtight, pressure-rated connection between the pump body and the plumbing — any wear, cracking, or thread damage at this point will cause pressure drop on the discharge side or loss of prime on the suction side. Replacing a worn nipple promptly keeps the pump operating at its rated flow and lift capacity.
