Frequently asked questions
What does the BE 85.400.200 kit include?
It includes eight O-rings: four sized for 1/4-inch quick-connect couplers and four for 3/8-inch couplers, covering the most common pressure washer fittings.
Why is my pressure washer leaking at the coupler?
A leak at a quick-connect fitting is usually caused by an O-ring that has worn, cracked, or fallen out. Replacing the O-ring restores a tight seal and stops the drip.
Will these O-rings handle hot water?
Yes. The seals are intended for both hot- and cold-water pressure washer service, making them suitable for degreasing and other heated applications.
How do I replace a coupler O-ring?
Remove the old or damaged O-ring from the coupler groove, clean the seat, and roll the correct-size replacement into place. No tools are required for most fittings.
