The Multiquip EE60291 Straight Fitting 3/8 Barb 3/8 NPT Male is a genuine OEM fitting designed for DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank units. This fitting provides a secure, leak-free connection between barbed hose lines and threaded ports, maintaining fluid integrity across both diesel fuel and DEF (diesel exhaust fluid) circuits. Sourced directly from Multiquip, EE60291 delivers the exact dimensions and thread specification required for a correct installation on compatible tank assemblies.
Key Features
- OEM-Spec Thread and Barb Dimensions — Manufactured to the exact 3/8-inch barb and 3/8-inch NPT male thread dimensions specified for these tank assemblies, ensuring a proper seal without adapters or modification.
- Direct-Connect Installation — Threads directly into the NPT-tapped port on the tank body and accepts a standard 3/8-inch barbed hose for a straightforward, tool-friendly installation.
- Compatible with DEFTANK1, DEFTANK2, and DEFTANK302 — Verified fitment across all three MQ Power Fuel and DEF Tank models in this series.
- Dual-Fluid Rated Design — Suitable for use in both diesel fuel and DEF fluid circuits, maintaining chemical compatibility across the corrosive demands of urea-based exhaust fluid.
- Genuine Multiquip OEM Part — Supplied as original equipment, meaning the material grade, thread engagement length, and barb geometry match what left the factory — critical in fluid fittings where substitution often leads to weeping connections or hose pull-off.
A straight barb-to-NPT fitting serves as the transition point between a rigid threaded port on the tank and a flexible hose line. The 3/8-inch male NPT threads seal against the tank's female port using thread sealant or tape, while the barbed end grips the inside diameter of a matching hose, held secure by a clamp. When this fitting cracks, corrodes, or develops thread damage, the result is fluid leakage at the tank connection — a particular concern in DEF systems where even small leaks can contaminate surrounding components or trigger emissions system faults. Replacing a damaged fitting promptly with the correct OEM part restores a leak-free seal and keeps the tank circuit operating as intended.
