The Multiquip 0191190525 is a genuine OEM Casing Cover Bolt 5/16-24 UNF designed for QP2TH and QP2TB series pump equipment. As a factory-sourced fastener, it meets the exact thread specification and torque requirements called out in the original equipment build — no guesswork on sizing or grade. This bolt is a direct hardware replacement for QP2TH and QP2TB units and installs in the same position as the original with no rework or modification to the casing. Sourcing the correct OEM fastener helps maintain a proper seal at the casing cover and keeps the pump operating as intended.
Key Features
- Correct Thread Specification — 5/16-24 UNF thread form matches the original casing cover hardware exactly, ensuring proper engagement and clamping force without cross-threading risk.
- Genuine OEM Construction — Factory-sourced fastener built to the same material grade and dimensional standard as the bolt it replaces, preserving the structural integrity of the casing joint.
- Direct Casing Cover Fitment — Engineered specifically for the casing cover assembly, dropping into the existing bolt pattern on QP2TH and QP2TB pumps without any drilling or rework.
- Confirmed Compatibility — Verified fit for QP2TH and QP2TB series Multiquip pumps; cross-reference part number 0191190525 before ordering to confirm your unit.
- Casing Seal Integrity — A correctly spec'd casing cover bolt maintains even clamping pressure across the cover gasket, preventing leaks and protecting internal pump components from contamination and pressure loss.
The casing cover bolt secures the outer casing cover to the pump housing, holding the internal impeller and volute assembly in proper alignment under operating pressure. When this fastener is stripped, under-torqued, or replaced with an incorrect thread pitch, the casing cover can shift or allow fluid to bypass the seal — leading to pressure loss, leakage, and potential damage to the pump internals. Using the correct OEM-spec bolt ensures the cover stays seated and the pump delivers consistent flow and prime under load.
