214843 - Miller 214843 Fuel Hose, SAE 1/4" ID x 1/2" OD x 10.25" CARB Approved

Technical Overview of Miller 214843 Hose

The Miller 214843 is a specialized replacement hose designed to meet stringent engineering standards for fluid transfer within industrial equipment. This component is characterized by its specific dimensional tolerances: an Inner Diameter (ID) of 0.250 inches and an Outer Diameter (OD) of 0.500 inches. The length is precision-cut to 10.250 inches, indicating its role as a specific jumper or connection line within a larger assembly, likely the fuel or emissions system of an engine-driven welding power source.

A critical specification of this hose is its "CARB Approved" status. This designation refers to the California Air Resources Board standards for Small Off-Road Engines (SORE). In the context of hoses, this typically implies a low-permeation construction designed to limit the evaporation of volatile organic compounds (VOCs) through the hose wall. Standard rubber hoses can allow fuel vapors to escape over time, contributing to smog and air pollution. A CARB-approved hose utilizes advanced barrier layers or specialized polymer compounds to significantly reduce this permeation, ensuring the equipment remains compliant with modern environmental regulations.

The SAE (Society of Automotive Engineers) reference in the product title further suggests adherence to industry standards for pressure, temperature, and chemical resistance. While the specific SAE standard (e.g., J30) is implied by the application, the dimensions and approval rating confirm its suitability for hydrocarbon-based fuels. Maintenance professionals sourcing this part can rely on the Miller 214843 to restore the original factory performance specifications of the machine, ensuring that fuel delivery or vapor recovery systems operate efficiently and safely without the risk of premature degradation found in generic bulk tubing.
