Hi Welcome to The Dart online store
Boom Hose with Spring.
What it is: A flexible high-pressure hose of about 61 inches length, with spring guards / spring at ends to prevent kinks or sharp bends.
Where used:
• On boom arms of pressure washers / wash stations, where hose needs to extend/retract.
• In mobile car wash rigs or stationary wash systems with a boom.
Function:
• Allows the hose to bend safely without getting damaged at connection points.
• Spring helps protect hose ends (where most wear happens).
• Lets the boom arm move while maintaining water flow.
When to replace / signs of wear:
• If hose leaks or bursts.
• If spring loses shape or doesn’t prevent bending.
• When water flow reduces because hose is partially collapsed inside.
• When connectors / fittings are damaged.
Important checks / specs:
• Inner diameter of hose (must match pump output and fittings).
• Pressure rating (psi/bar) suitable for your pump.
• Spring design (how rigid it is) to protect from repeated flexing.
• Compatibility of fittings at both ends (thread type, size).
