Triton thrasher - the piece of clip wire in the photo below is too close to the flat of the JCC/Hepolite pin - it could push out the clip. There is not enough champer on the pin to be safe. And the fact is that JCC clips are coming loose. This does not happen with JE pistons/pins/clips.
oOnortonOo is right - the tangs on the JCC/hepolite clips are an accident waiting to happen. And they would rub on the flat of a pin even if the pin was chamfered - the pin would push out the clip at the tangs - then the entire clip would come out and eat away at the cylinder wall.
Go back and look at oOnortonOo photo of Emgo (?) wire clips on the previous page. You can see that the top clip is worn flat on one side from rubbing against the pin.
