Nathan1991 25 Posted March 4, 2014 Report Share Posted March 4, 2014 He guys nathan again, Just a quick post, I have recently acquired a hw35k and have extensively restored it, one of the things that I needed to do was to replace the breach seal. After removing it I noticed that it wasn't in bad nick but felt slightly hard. So I decided to try an experiment to re condition it and here's what I did. 1- cleaned off the excess gunk 2- mixed together equal parts moly grease and liquid detergent 3- left the seal in it overnight 4- took it out the next day and cleaned it off 5- take a plastic party cup and put a tsp of petroleum jelly in it 6- take a coffee mug And half fill it with hot water (not boiling) and place the party cup in it and let it totally melt until clear 7- place the seal in the cup and leave to stand until the water is cool 8- take the seal out and dab off excess And presto you have a re-conditioned breech seal, I do not know exactly how it works but it does and is extremely effective, the breach is softer and fuller going to chrono it later to see if the ftlb has increased by any. Thanks for reading 2 Quote Link to post

Hi secretagentmole, I know they are cheap that's why I thought "I've got nothing to loose" if it hadn't worked or if it started to dissolve it I would just order one. Experimenting with things like this helps me understand how it works I will however bare that in mind in future. Perhaps the moly paste broke the detergent down a little :/.

secretagentmole 1,701 Posted March 5, 2014 Report Share Posted March 5, 2014 I can understand that, but please bear in mind that different rubbers/plastics can react to different solvents or detergents in different ways, it could be slowly degrading and you don't know it. Best get it replaced with a new one soon as possible, it is an HW, you owe it that! Quote Link to post
