[QUOTE="greg brillus, post: 122689, member: 597"] Always love your work Vic........On standard cases and tubes, use a 3 mm "O" ring i can't remember the exact specs, but you want the O ring to be a snug fit into the case recess, then with a tiny smear of sealant or similar, you should be able to push the tube down into the o ring and feel it compressing the sides of the O ring and form a good seal........generally you will end up with a gap at the top on account of the O ring being much smaller than the original seal.......this is where I also use a slightly smaller section O ring 2.5 mm in section above the other one and this acts as a "Packer" thus filling the gap and stopping crud filling the area. It also helps with the installation as it will hold the gland nut up and out of the way until the head/barrel are fully home on the studs. Using a small amount of sealant not only helps the tube seal against the O ring, it helps the tube to slide nicely into the O ring without it causing the O ring to "roll" or twist as the tube enters through it. Once you are happy and have successfully started the gland nuts into the head and the nuts nipped up, you can massage the other O ring down the tubes and into the case using a small flat screwdriver blade. I have never had any come loose or slip out of the recess, so I don't see any need for special machined holders or similar. The tubes need to be able to move sideways as the head/barrel settle into place, the O rings are perfect for this. [/QUOTE]
