Multiquip 0481311100 O-Ring Nipple G110

The Multiquip 0481311100 O-Ring Nipple G110 is a genuine OEM sealing component designed for QP402H, QPT405SLT, and QP402B centrifugal pumps. Sourced directly from Multiquip, this O-ring delivers the exact material grade and dimensional tolerancing required to maintain a leak-free seal at the nipple connection. Verified fitment across the QP402 and QPT405 series means this part installs correctly without modification. Keep a spare on hand — seal failure at the nipple can result in fluid loss, pressure drop, and unplanned downtime on dewatering or pump-out operations.

Key Features

• Exact Material and Dimension Match — Manufactured to OEM specification, this O-ring provides the correct compression profile and elastomer grade for a reliable seal at the nipple fitting — no guesswork on sizing.
• Direct-Swap Installation — Seats into the existing nipple groove on compatible Multiquip centrifugal pumps without any machining or adapter hardware.
• Confirmed Centrifugal Pump Fitment — Validated for QP402H, QPT405SLT, and QP402B pump models; use part number 0481311100 to confirm compatibility before ordering.
• Leak Prevention at the Source — A properly seated O-ring at the nipple port maintains system pressure and prevents fluid bypass that would reduce pump output and stress downstream components.
• Genuine OEM Part — Backed by Multiquip's OEM quality assurance, ensuring this seal meets the same standards as the original component installed at the factory.

An O-ring at the nipple connection acts as a pressure seal between two joined fluid passages, preventing liquid from escaping at the joint under operating pressure. In centrifugal pump applications, even a minor breach at this seal can cause measurable pressure loss, reduce flow output, and allow fluid to migrate into areas of the pump where it can accelerate wear. When an O-ring hardens, cracks, or takes a compression set over time, it loses its ability to conform to the mating surfaces — replacing it with the correct OEM part restores the integrity of the fluid circuit and ensures the pump performs to its rated capacity.
