Fit and worked
The Trigger valve worked great the only rub was the waiting for the part but at this time it was understandable - Covid -19 . Past orders also fit and worked !

disappointed outcome
I ordered a kit, I received the part only,no other parts. I tried to get in touch through your web site, but got nowhere. I couldn't contact anyone. I tried to do a chat, but got an E mail back saying I had the wrong place. So I went on U tube and watched a video on how to replace a trigger valve. I had a nail the approximate diameter and used that to drive out the pins. I also felt payed more than the part was worth, Ended up that wasn't the problem, so now I'm going to do a rebuild on the nailer. Im going to get the kit from another company.

Does this fit my product?Questions & Answers for Trigger Valve Kit
Hi, I was wondering what the lube is for installing a new Trigger Valve?

Hello Ben, Thank you for the question. You will need to use it on the the Seals on the valve before installing so it can seal and function properly. We hope this helps!

Time

Tools Used
, hex wrench, small hammer, included punch
Followed the simple instructions included with the parts. The only hiccup was that one drawing on the trigger kit, sequential pointed to the wrong pin to remove the trigger, but that became obvious when I looked closely at the tool. The hint to use compressed air to expel the old trigger valve was valuable.
