Question for people who've used floating o-rings

Unread postAuthor: Gun Freak » Thu Jul 01, 2010 6:12 pm

... with a bolt/washer/nut combo. Couldn't fit all that in the title.

Anyway, the washer has two sides. One is square and the other is rounded. Which one is better to use?

Are you asking which side is better to have the o-ring seal against? If so, the flat side is preferable.

People should not be afraid of their governments. Governments should be afraid of their people.

Actually, it probably doesn't matter. I might suggest putting the slightly rounded sides against the o-rings, the squared off sides might cut into or damage them with repeat operation. Just a guess though, it will no doubt seal better on the squared off sides though.

Yeah that's what I was thinking but if it would seal better on the square side then that's what I would use. Thanks.

For floating o-rings, you definitely don't want to have exposed sharp edges on the sealing face of the washer, as the o-ring may become damaged when it shifts back and forth in the groove. However, for optimal sealing, it's still better to position the relatively flat surface towards the inside. As you said, it probably doesn't make a whole lot of difference in this application, but I'd rather ensure the best seal possible.

But you know what I'm saying about the edges of the washer right...

As above, a slight bevel on the edge will ensure that the o-ring won't get torn, without affecting the capability of the rubber to seal.
