Captain O-Ring - Power Pressure Washer O-Rings for 1/4" Quick Coupler, High Temperature Viton FKM (10 Pack)

Works as it should, fit right in mind (can’t remember brand)

Good quality work well in my Hotsy

Perfect fit for my air compressor.

Edit; I have changed my rating as this company has bent over backwards to solve the issue. Customer service means everything to me as well as a useful product. They sent me a second set with a smaller outside diameter, but they are too small. That's okay, they are being extremely helpful, and I thank them!I purchased these to replace a couple of O-rings on my pressure washer hose. I installed one onto the end of the hose and now it will not fit into either the pump outlet or the wand. The outside diameter of the o-ting is simply two large. I went to Home Depot and they had some and they work perfectly. waste of money.

Amazon does it again and in 1 day gets me the part I need to get my project done. Other sites might have been a few bucks cheaper but here I was assured 1 day delivery. My hose was new but the pressure washer company did not grease the rings and after on winter they were cracked/split. These did the trick.

I'm really impressed with these . They are tough . I pressure wash produce trailers for Dole and Chiquita with a heated water and they last haven't had to change it out much as compared to other brands quite often. Thank you a wonderful product at which you don't see much these days

o-ring is too thick to use for a Stihl power washer. I had to use a file to make it thin enough to make it fit.Update from 1-star review: Jon from Captain O-ring helped to find a usable o-ring to fit a Stihl power washer hose. Instead of 3/8" X 0.100" a 3/8" X 0.070" with 2 o-rings for each hose nozzle now doesn't leak.

Perfect fit my pressure hose fittings. This size is hard to find.
