The Multiquip AO100500225 is a genuine OEM Screw 1/2" x 2-1/4" Hex designed for the SDP-2 diaphragm pump. As a direct OEM replacement sourced from Multiquip, this hex screw matches the original hardware specification for the SDP-2, ensuring correct clamping force and a properly sealed pump assembly. If you are servicing or rebuilding an SDP-2 diaphragm pump, using the correct OEM fastener is essential to maintaining a leak-free, structurally sound connection.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the original thread pitch, head dimensions, and material grade specified for the SDP-2 diaphragm pump, ensuring consistent torque performance and clamp load.
- Drop-In Hardware Replacement — The 1/2" x 2-1/4" hex configuration installs directly into existing pump housing bolt patterns with no reworking of mounting surfaces required.
- Confirmed Fitment for SDP-2 — Verified for use on the STOW SDP-2 diaphragm pump series, so you can order with confidence knowing this is the correct fastener for your machine.
- Leak Prevention at the Source — A worn, stripped, or incorrect screw compromises the clamping pressure on diaphragm housing covers and flanges, leading to fluid bypass and pump failure. The correct fastener maintains the seal where it counts.
- Genuine OEM Part — Supplied as an authentic Multiquip OEM component under part number AO100500225, giving you the same hardware that ships with new SDP-2 units from the factory.
The Screw 1/2" x 2-1/4" Hex is a structural fastener used to secure the diaphragm housing, cover plates, or flanged connections on the SDP-2 diaphragm pump. It maintains the compressive force needed to keep pump chambers sealed against fluid pressure during operation. When this fastener is missing, damaged, or replaced with an incorrect substitute, the housing joint can work loose under vibration, allowing fluid leakage, pressure loss, and potential pump shutdown.
