Title: air leak on AT44 hatsan
Post by: Ratpaker on February 25, 2015, 02:50:52 AM

I have a hatsan at44 that has an air leak from the small bleed hole about 1 1/2 inches back from the gauge end?
Im guessing it is just an o-ring but before I go pulling it to bits, has anyone done this before?
Any pointers or advice?
Thanks in advance!

Pretty simple fix.  Make sure tank is EMPTY,  unscrew fill port assembly, replace oring, lube oring with silicone reassemble, done.

Excellent work, I suspected that was  the size from the exploded diagrams they show on the hatsan website.
Thank you very much for your help!
