The 290685 airless hose is a direct replacement high-pressure fluid line for hydrax 4540 - 7230 equipment. This 3 foot long hose features a 1/8 inch inner diameter and is rated for pressures up to 4500 PSI, meeting the demanding requirements of airless spray applications. It is constructed with a durable inner tube compatible with a wide range of coatings, reinforced with multiple layers of high-strength braid to withstand operating pressures, and protected by an abrasion-resistant outer cover. The hose includes factory-installed end fittings for secure, leak-free connections to the pump outlet and spray gun. A properly functioning hose delivers material smoothly and safely. A damaged or worn hose can cause fluid leaks, pressure drops, and potential safety hazards. This replacement hose is manufactured to exact length and fitting specifications for direct replacement. The 3 foot length is ideal for tight spaces or for use as a whip hose between a longer main hose and the gun, providing flexibility and reducing operator fatigue. Regular inspection of hoses helps identify wear, cracking, or abrasion before they lead to failure.
