Bought this for my 15mm electric Stanley 2150 pressure washer, make sure you don't buy the 14mm for this unit, DON'T BUY THE 14mm, it will not fit, this is a perfect fit for this model, so far the seal seems to be holding with only minor leaking (may have been because I didn't turn and try to adjust), hope the seal continues to hold with limited or no water leakage at any access point, I used all but one adapter (hose to unit, unit to gun), pressure washer seems to be running better with these new adapters because water is flowing more consistently, it may take some adjustment to get your fit perfect but once all adapter are in place, its so easy to plug and unplug, especially great if you want to head out for a quick pressure wash and it's very cold out, you can unplug everything quickly to let is drain and you won't have any weather related issues, overall a great buy!
