Multiquip P3363 3/8 NPT 5/8 Barb Fitting

The Multiquip P3363 3/8 NPT 5/8 Barb Fitting is a genuine OEM fitting designed for C30HDNI series Mayco concrete pumps. This direct-replacement hardware component ensures a secure, leak-free connection between hose and threaded port, maintaining the fluid integrity your pump system depends on. Sourced directly from Multiquip, the P3363 is built to the same specifications as the original, confirming fitment for C30HDNI and C30HDNI Precision models.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original hardware specifications, ensuring correct thread engagement and barb retention for a leak-free connection in concrete pump fluid lines.
• 3/8 NPT Thread x 5/8 Barb Configuration — Matches the original port and hose diameter exactly, installing directly into the threaded fitting seat without modification to the mating hose or pump housing.
• Confirmed Fitment for C30HDNI Models — Verified for use on C30HDNI and C30HDNI Precision Mayco concrete pumps, so you can order with confidence.
• Maintains Pump System Pressure Integrity — A worn or cracked barb fitting can cause fluid leaks and pressure loss in the pump circuit; replacing it with the correct OEM part restores proper system performance.
• Fuel and Fluid Line Safety — A correctly seated barb fitting prevents uncontrolled fluid release in pressurized pump circuits, supporting safe operation on the jobsite.

A barb fitting serves as the transition point between a rigid threaded port and a flexible hose in a fluid circuit. The NPT (National Pipe Taper) threaded end creates a pressure-tight seal when threaded into the pump housing, while the barbed end grips the interior wall of the hose to hold it firmly under pressure. When a barb fitting cracks, corrodes, or strips, it can allow fluid to leak at the connection point, reducing pressure to downstream components and creating a potential hazard. Replacing a failed fitting promptly with the correct OEM specification part restores a reliable seal and keeps the pump circuit operating as intended.
