The Multiquip 171601000 is a genuine OEM Knob 1/4"-20 x 1/2" designed for Multiquip diaphragm pump models MQD2H and MQD3H. As a direct Multiquip OEM part, it meets the exact material and dimensional specifications of the original hardware — ensuring consistent fit and correct retention. DHS Equipment stocks this part to help you get your pump back in service without the guesswork of sourcing a substitute.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to the exact 1/4"-20 thread pitch and 1/2" length specification of the original Multiquip component, ensuring proper thread engagement and torque behavior.
- Drop-In Installation: — Threads directly into the existing mounting point with no re-tapping, drilling, or hardware modification required.
- Confirmed Fitment for MQD2H and MQD3H: — Verified for Multiquip diaphragm pump models MQD2H and MQD3H, so you can order with confidence against your machine's model code.
- Maintains Secure Panel and Cover Retention: — A correctly sized and threaded knob keeps access panels, covers, or control components firmly seated during operation, preventing vibration-induced loosening common on pump equipment.
- Sourced Direct from Multiquip OEM Supply: — Backed by Multiquip's OEM parts program and sold through DHS Equipment as an authorized distributor.
A thumb knob on diaphragm pump equipment serves as a hand-tightened fastener used to secure access covers, filter housings, or adjustable components without the need for tools. Because diaphragm pumps generate continuous vibration during operation, the knob must maintain its thread engagement reliably — an undersized, cross-threaded, or worn knob can allow panels to shift or rattle loose, exposing internal components or disrupting pump adjustments. Replacing a damaged or missing knob with the correct OEM part restores the intended retention and keeps the pump operating as designed.
