Overview

The Male QC Coupler in 1/4 inch is a stainless steel quick connect coupler for pressure washer lines. A quick connect system has two halves: the coupler and the plug. This is the coupler half with the male connection, so it mounts on the machine or hose side and accepts the matching plug to make a fast, tool free connection between the pressure washer and the accessory.

The stainless steel body is the difference on this fitting. Stainless resists the corrosion that plated steel sees in constant wet use, so the coupler keeps its action smooth on a machine that is connected and disconnected all day. It is the trade grade choice for the delivery line, where a seized coupler costs time on site. Confirm the thread standard on the machine port before ordering, so the coupler screws on cleanly the first time rather than fighting a mismatched thread.

What You Need to Complete the Job

Frequently Asked Questions

What is the difference between a coupler and a plug?

The coupler is the half with the release collar, usually mounted on the machine or hose side, and the plug is the half that slides in to lock. Together they make a quick connect joint that is made and broken by hand without tools.

What thread does the coupler use?

The listing states the coupler is a 1/4 inch male, which is the 1/4 inch NPT thread used across the stainless quick connect range. The matching plug in the range is the 1/4 inch plug with a 1/4 inch NPT female thread.

Why stainless steel?

Stainless resists the corrosion that a pressure washer line sees in constant wet use, so the coupler keeps its action smooth and does not seize on the threads. It is the trade grade choice for a fitting that is used every day.
