Fix it, don’t trash it! If your nailer is leaking air replace the seal. Easy peasy!

Not much to say here, it's a plastic ring that prevent air from leaking, it does its job, case closed.

If you notice a need for more air pressure, this is probably your culprit. Runs like a new gun when you replace the seal

This did the trick to fix my nail gun. I gave it 3 stars because they could easily make it from a better material that wouldn't dry up and crumble in the nailer but they would rather make low quality parts.

Didn't use my DA250B for a few years, tried it, and it just blew exhaust. This collar and the 904750 seal (bumper) had rotted. Not quite back in business because I keep receiving the wrong part in a 904750 bag, but this 904749 collar fit perfectly.
