How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Threaded Swivel Hose Fittings for Water
Use these fittings with power washer guns and in other high-pressure water supply applications. They have ball bearings, so they can swivel 360° before and after installation as needed to prevent hose kinking. Fittings are 416 stainless steel for good corrosion resistance.

High-Pressure Quick-Disconnect Hose Couplings for Water
Larger, heavier, and rated for higher pressures than our standard open-flow hose fittings, these couplings maximize flow in high-pressure washing applications, such as water blasting. They don't have a shut-off valve, so water flows freely through. A complete coupling consists of a plug and socket (both sold separately) that connect and disconnect quickly. They’re compatible with Parker WB and Eaton/Aeroquip FD69 couplings.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Note: Pressure ratings are given for static (constant) pressure conditions.
Warning: Stop the flow before you disconnect the line.

Quick-Disconnect Wash Gun Extensions
Clean hard-to-access areas by extending the reach of your quick-disconnect wash gun. These extensions have a threaded coupling for your wash gun and a quick-disconnect coupling for your nozzle. Made of zinc-plated steel (with brass and stainless steel couplings), they’re durable and have good corrosion resistance. They’re commonly called extension wands.
Nozzles are required, but not included; see quick-disconnect spray nozzles.

Pressure Washer Extension Wands
To clean hard-to-reach areas, attach this wand to your pressure washer. The wand fits most pressure washers. For nozzle (not included), see quick-disconnect spray nozzles.
