If it’s broken or busted, it’s likely we’ll have a replacement or solution; if you can’t identify it or don’t know what it’s called, just ask our Parts Guru. This highly sophisticated algorithmic paragon of industry expertise combines more than two centuries’ worth of Duff knowledge. Just ask!
The Duff Difference means we are committed to the widest product selection and deepest inventory, focused on professional maintenance and facilities departments. In addition to pipe, valves and fittings, china, faucets, flushometers, water coolers–the types of products that keep a facility running everyday–we also stock that oddball item you didn’t even know existed. We see our job as making your job easier. Duff team members are available and on-call for emergency service, 24 hours a day, 365 days a year.
