The Multiquip 0131191290 is a genuine OEM Cap Screw (Casing) M12 X 90 designed for QP3 series centrifugal and trash pump models. As a direct OEM replacement sourced through Multiquip's authorized parts network, this fastener meets the exact grade, thread pitch, and dimensional specifications required for proper casing assembly. Confirmed fitment includes QP3TB, QP3THX, QP3TK, QP3TS, QP3TH, and QP3TZ pumps. Using the correct OEM cap screw ensures the pump casing is secured to specification, protecting the integrity of the pump housing and internal components during operation.
Key Features
- OEM-Grade Fastener Specification — Manufactured to the correct M12 x 90 thread standard and material grade, ensuring proper torque retention and casing seal integrity.
- Direct Casing Bolt Replacement — Engineered to thread directly into the existing pump casing mounting points with no rework or re-tapping required.
- Broad QP3 Series Compatibility — Confirmed for QP3TB, QP3THX, QP3TK, QP3TS, QP3TH, and QP3TZ pump models.
- Casing Integrity Under Pressure — A properly torqued casing cap screw keeps pump housing halves aligned and sealed; a failed or incorrect fastener can cause casing separation, fluid leaks, and pump damage.
- Genuine Multiquip OEM Part — Supplied directly through the Multiquip authorized parts channel under part number 0131191290, so you can verify fitment with confidence before ordering.
The casing cap screw is a structural fastener that clamps the pump casing halves together, maintaining the sealed housing that directs fluid through the impeller and volute. Without correctly rated and properly torqued casing bolts, the pump housing can shift under operating pressure, leading to fluid leakage, loss of prime, or accelerated wear on internal sealing surfaces. Replacing worn, stripped, or damaged casing fasteners with the correct OEM specification screw is a straightforward but critical step in any pump rebuild or reassembly.
