Multiquip 0481310800 Nipple O-Ring

The Multiquip 0481310800 is a genuine OEM Nipple O-Ring designed for QP3TB, QP3TH, QP3THX, QP3TK, QP3TS, QP3TZ, and QPT405SLT pump models. As a factory-sourced component, it meets the exact material and dimensional requirements set during original manufacture — ensuring a proper seal every time. Multiquip 0481310800 is the correct replacement choice for both centrifugal and trash pump applications across this pump family. Verify your model against the fitment list before ordering to confirm compatibility.

Key Features

• OEM Sealing Material: — Manufactured to the original compound and durometer specification, delivering the compression and chemical resistance required for pump fluid connections.
• Direct Nipple Connection Fit: — Seats precisely at the nipple joint, restoring a leak-free interface without trimming, stretching, or additional hardware.
• Broad Pump Family Coverage: — Fits QP3TB, QP3TH, QP3THX, QP3TK, QP3TS, QP3TZ, and QPT405SLT, spanning both centrifugal and trash pump configurations.
• Leak Prevention at the Source: — A correctly seated O-Ring at the nipple maintains system pressure and prevents fluid bypass that would reduce pump output and cause external weeping.
• Fluid System Integrity: — Replacing a worn or cracked O-Ring before it fails keeps the pump's discharge circuit sealed and prevents contamination ingress at the connection point.

An O-Ring at a nipple fitting acts as the primary radial or face seal between two fluid-carrying components, compressing under assembly to block any path for liquid to escape. In pump applications, this connection point is under continuous pressure during operation, meaning even a minor degradation in the O-Ring's profile or elasticity can result in visible leakage, pressure drop, or fluid contamination around the joint. When an O-Ring hardens, cracks, or takes a permanent set, it loses its ability to conform to the mating surfaces and must be replaced promptly to restore a reliable seal.
