The Multiquip 0131151225 is a genuine OEM Cap Screw M12X25 Suction Cover designed for QP4TB, QP4TK, QP4TKT, QP4TZ, and QP4TH series trash pumps. As a factory-original fastener, it delivers the correct thread pitch, grade, and dimensional spec needed to properly secure the suction cover on these quick-prime units. Sourced directly from Multiquip, part number 0131151225 ensures a direct, hardware-matched replacement with no guesswork on sizing or thread compatibility. If you're servicing or rebuilding the suction end of your QP4T-series pump, this is the correct cap screw for the job.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the exact M12x25 thread specification and tensile rating required for suction cover retention on QP4T-series trash pumps, ensuring proper clamping force without risk of stripping or under-torquing.
- Direct Suction Cover Fit — Threads directly into the suction cover mounting points with no rework or hardware substitution needed — same bolt pattern, same engagement depth as the original.
- Broad QP4T Series Coverage — Compatible with QP4TB, QP4TK, QP4TKT, QP4TZ, and QP4TH trash pump models, making it a reliable stock item for fleets running multiple QP4T units.
- Maintains Suction Integrity — A correctly torqued suction cover fastener is critical to maintaining the pump's prime. A loose, damaged, or incorrect bolt allows air infiltration at the suction face, causing the pump to lose prime and drop flow performance mid-operation.
- Verified Multiquip Part Number — Ordering by OEM part number 0131151225 eliminates cross-reference errors and ensures you receive the correct fastener the first time, which matters most during unplanned field repairs.
The suction cover cap screw secures the suction cover plate to the pump casing, creating the sealed interface that allows the pump to draw fluid from the source. On quick-prime trash pumps like the QP4T series, maintaining a properly sealed suction side is essential — any gap or looseness at the cover joint allows air to enter the suction path, breaking the pump's prime and preventing it from moving water effectively. A worn, cross-threaded, or missing cap screw at this location is one of the most common causes of prime loss during pumping operations. Replacing it with the correct OEM fastener restores the integrity of that seal and keeps the pump operating as intended.
