The Multiquip 316017000 is a genuine OEM NPT Pipe Nipples Pack of Two designed for the MQD2H, MQD2HA, MQD3H, and MQD3HA diaphragm pump series. These threaded pipe nipples provide the secure, leak-free plumbing connections that diaphragm pumps depend on during demanding fluid transfer operations. Sourced directly through Multiquip's authorized parts network, 316017000 ensures a correct, thread-matched fit with no guesswork on sizing or compatibility. Sold as a convenient pack of two, this listing keeps your service stock ready for routine maintenance or field repairs.
Key Features
- Genuine OEM Thread Specification — Machined to the exact NPT thread form and dimensions specified for Multiquip diaphragm pump plumbing circuits, ensuring a pressure-rated seal at every connection point.
- Direct Plumbing Replacement — Threaded nipples install directly into existing pump ports and manifold fittings on MQD2H, MQD2HA, MQD3H, and MQD3HA models without re-tapping or adapter fittings.
- Confirmed Fitment for MQD Series Pumps — Verified for the MQD2H, MQD2HA, MQD3H, and MQD3HA diaphragm pump models, covering both standard and high-performance configurations in this family.
- Pack of Two for Efficient Servicing — Supplied as a matched pair so both inlet and outlet connections can be renewed in a single service interval, maintaining balanced flow performance across the pump.
- Leak Prevention at the Source — Worn or damaged pipe nipples are a common cause of fluid weeping and pressure drop in diaphragm pumps; replacing with genuine OEM hardware restores rated discharge pressure and protects downstream hoses and fittings.
Pipe nipples are externally threaded fittings that connect the pump's inlet and outlet ports to the broader plumbing circuit — hoses, manifolds, or discharge lines. In a diaphragm pump, these fittings carry fluid under cycling pressure loads, making thread integrity critical to leak-free operation. When a nipple corrodes, cracks, or strips, the resulting leak reduces discharge pressure, introduces air into the system, and can cause premature wear on surrounding seals and valves. Replacing damaged nipples promptly with correctly rated OEM hardware keeps the pump delivering consistent flow output and extends the service life of the entire fluid end assembly.
