OK this might sound like I

Brian,
I sure do the same thing. Absolutly they work better when they are softened up a bit. I don't like it when they are brand new.

brian,

At what time do you flip those? after a couple uses or when it has already started flaring out?

WOW!! You dug pretty deep to find this post this was an old one congratulations on reading the entire forum.

I usually flip them after the end has flared out after several uses there pretty much worn out.

As far as the little nub it

I thought I was the only one. When I first got my kit I was a little confused as to how to install the seals and saw a little difference in the two sides but I found them to work both ways. Come to find out they do have a proper way to install!! What a deal!!! What about color or style, I got some of the black seals from Delta and while they are a little harder to see damage with I really like them. (They outlast the white seals.) Scott

Hi All,
I work in the Plastics industry, the little "nub" you refer to is called the "Gate", it is where molten plastic material is injected into the cavity which forms the seal, it is totally normal, it does not really identify which way round it goes, however, I expect that having it at the tip of the seal would be best, as it may effect the seal inside the injector by distorting the seals shape slightly.

On a more technical note, the area by the gate will be more "packed out" which means it may be slightly more rigid then the other end of the seal, which may also be of benifit if it is installed so that it is the end that touches the glass.

Hope this clears it up for you...

Scott,

Actually, the mold we have for these seals is made with a tapered internal cylinder. It is made of Kraton, and this nub/gate is at the larger end of this cylinder by design, so that the plunger goes into the large end and down towards the taper.

Don't know about other things in the plastics industry, but in this case, put the nub/gate on the inside of the injector.

Hi jeff,
That is fine, the tapper makes sense, plus the direction of the taper also makes sense with conventional tooling design, I had not looked that closely to check for dimensions, my comments were from a design/process knowledge of what I would expect see, I mainly wanted to clarify what the "nub" was all about.

Have a good one.

Its ok your on the bottom of the world everything looks upside down from there Or I guess depending how you look at it maybe we are upside down?
