Multiquip 0481310550 Nipple O-Ring

The Multiquip 0481310550 is a genuine OEM Nipple O-Ring designed for QP2-series trash pumps and centrifugal pumps, including the QP2TH, QP2TK, QP2TZ, QP2TB, QP2B, and QP2H. As a factory-sourced component, it meets the exact material and dimensional specifications required for a proper, leak-free seal. Sourced directly through authorized Multiquip distribution, this O-Ring ensures your pump connections perform as intended with no guesswork on fitment. If you're maintaining or rebuilding a QP2-series pump, verifying you have the correct part number — 0481310550 — before you start the job keeps the work moving.

Key Features

• OEM-Grade Seal Material — Manufactured to Multiquip's exact compound and durometer specification, ensuring the correct compression and chemical resistance for pump nipple connections.
• Drop-In Replacement — Matches the original O-Ring profile at the nipple fitting, seating cleanly without trimming or modification to the mating surfaces.
• Broad QP2 Series Fitment — Compatible with QP2TH, QP2TK, QP2TZ (trash pump models) and QP2TB, QP2B, QP2H (centrifugal pump models), covering a wide range of Multiquip QP2 pump configurations.
• Leak Prevention at the Nipple Joint — A failed or degraded O-Ring at this location allows water or slurry to bypass the nipple connection, causing pressure loss and potential damage to surrounding fittings.
• Genuine OEM Confidence — Part number 0481310550 is a Multiquip factory part, not an approximation — critical when seal geometry directly affects pump output and connection integrity.

An O-Ring at a nipple fitting creates a compressed, fluid-tight seal between two joined components, preventing liquid from escaping at the threaded or push-fit connection point. In pump applications like the QP2 series, this seal is under continuous pressure and exposure to water, debris, and varying temperatures, which causes the rubber compound to compress, harden, or crack over time. When the O-Ring fails, the connection weeps or leaks outright — reducing pump efficiency and, in trash pump applications, potentially drawing air into the system and disrupting prime.
