Poly Hose Barb - Simple, Corrosion-Resistant Hose Connections
This poly hose barb connects flexible hose to threaded ports, with MPT thread on one end and a barbed tail on the other. It comes in 3/8", 1/2", and 3/4" MPT x hose sizes. Poly won't rust, and it stands up to the chems that eat metal fittings.
Contractors use these barbs on chemical suction lines, downstream soap hose, and tank plumbing all over a rig. Slide the hose over the barb, clamp it, and you've got a solid connection. In stock at Sun Brite Supply in Gaithersburg, MD.
Where Contractors Use This Hose Barb
Application and Compatibility
This component integrates into standard commercial pressure washing systems using industry-standard connections. Verify the specifications listed below against your existing equipment before ordering. Thread sizes, pressure ratings, and flow capacities must match your system for safe, leak-free operation. If you're not sure about compatibility, call (301) 519-9274 - we match parts to machines every day.
Contractor-Grade Quality
There's a real difference between professional equipment and consumer-grade alternatives sold at hardware stores. Consumer parts are built to a price point - they work fine for the homeowner who pressure washes their deck once a year. But put those same parts on a commercial rig running 8 hours a day, 5 days a week, and they fail fast. This pressure washer part is built for that daily grind. The materials, tolerances, and construction are designed for thousands of hours of commercial operation. That's why contractors come to Sun Brite Supply instead of buying online from unknown vendors - we carry the brands and specs that working professionals trust.
Installation and Setup
Verify Compatibility
Check the specifications against your existing equipment. Thread sizes, pressure ratings, and flow capacities must match for safe operation.
Install According to Specs
Follow the manufacturer's installation guidelines. Use appropriate thread sealant on pipe connections. Don't overtighten fittings.
Test Under Pressure
After installation, test at low pressure first. Check all connections for leaks before running at full operating pressure.

Maintenance and Troubleshooting
Inspect this component during your regular maintenance routine. Check for wear, leaks, corrosion, and proper operation. Replacing worn parts on schedule prevents mid-job failures that cost you time and money.
When to Replace vs. Repair
If this pressure washer part shows signs of wear but is still functional, a rebuild kit or replacement seals may extend its service life at a fraction of the full replacement cost. However, if you see cracks, cross-threading, severe corrosion, or complete failure under pressure, replacement is the safer and more economical choice. Call (301) 519-9274 and we'll help you decide. Always follow OSHA equipment safety standards when working with high-pressure equipment.
