The Multiquip AO100250125 is a genuine OEM Hex Screw 1/4"-20x1-1/4" designed for STOW Diaphragm Pump equipment. Sourced directly from Multiquip, this fastener meets the original design specifications for the SDP-2, ensuring a proper fit in every application. Keeping the correct hardware in place is essential for maintaining a secure, leak-free assembly on diaphragm pump systems. DHS Equipment supplies this part ready to ship so you can get your pump back in service fast.
Key Features
- Correct Thread Specification — 1/4"-20 thread pitch and 1-1/4" length match the original fastener spec, so hardware seats flush and torques correctly without cross-threading or misalignment.
- Genuine OEM Construction — Manufactured to Multiquip's original material and hardness grade, delivering the clamping force needed to keep pump housing components sealed under operating pressure.
- Direct Replacement for SDP-2 — Engineered specifically for STOW Diaphragm Pump models, this screw drops into the existing threaded bore without rework or substitution.
- Structural Integrity Under Pump Vibration — Diaphragm pumps generate continuous cyclic vibration; using the correct OEM fastener maintains proper clamp load and resists loosening over time.
- Fluid System Safety — A correctly spec'd and properly torqued fastener is critical on pump housings where loose hardware can cause fluid leaks, pressure loss, or component separation during operation.
A hex screw of this specification serves as a structural fastener within the pump housing or cover assembly of a diaphragm pump. It holds mating components together under the mechanical stress and cyclic pressure changes that diaphragm pumps experience during normal operation. When the wrong fastener is used — or when the correct one is worn, stripped, or undertorqued — housing joints can weep fluid, lose prime pressure, or fail to contain pump output, creating both performance and safety concerns.
