The Multiquip 0131191235 is a genuine OEM Casing Cap Screw M12 x 35 designed for QP2T and QP3T series pumps, including trash pump models QP3TH, QP3TZ, QP2TZ, QP3TS, QP2TK, QP3TK, QP3THX, and QP2TH, as well as centrifugal pump models QP2TB and QP3TB. As a factory-sourced fastener, it meets the exact thread pitch, grade, and dimensional specs Multiquip engineers specified for these pump casings. This is a direct OEM replacement, so it threads in exactly where the original hardware did — no chasing threads or fitment guesswork. Keep a spare on hand and your pump stays sealed and service-ready.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to the exact M12 x 35 thread specification and torque rating required to maintain a secure, pressure-tight pump casing joint.
- Direct Hardware Replacement — Replaces the original casing bolt position-for-position, threading directly into existing casing bosses on QP2T and QP3T series pumps.
- Broad QP Series Fitment — Compatible with QP3TH, QP3TZ, QP2TZ, QP3TS, QP2TK, QP3TK, QP3THX, QP2TH, QP2TB, and QP3TB pump models.
- Casing Seal Protection — A correctly torqued casing bolt holds the pump halves tight against the gasket or seal surface; a worn or missing fastener allows pressurized fluid to escape at the casing joint.
- Pressure-Side Safety — Pump casings operate under internal fluid pressure; using a correctly rated OEM fastener prevents casing separation and uncontrolled fluid discharge during operation.
The casing cap screw is the primary fastener that clamps the pump casing halves together, compressing the seal or gasket between them and keeping the internal fluid path fully contained. Without a properly rated bolt torqued to spec, the casing joint can weep or separate under pressure, allowing pumped material to escape and causing the pump to lose prime. On trash and centrifugal pump models, where casing integrity is critical to maintaining suction and discharge pressure, replacing a damaged or missing casing bolt with the correct Multiquip 0131191235 hardware restores the joint to its original clamping force.
