Subject: What type of Teflon for headers?

<DIV>I just replaced the umpteenth Teflon header on my plane, this one after 9 flights. The headers are made from PTFE?tubing purchsed from McMaster-Carr.?For grins I purchased blue tubing to match my plane. The failure seems to be caused by the header rotating in the teflon, eroding the inside until it fails. I am using a header brace, and I add a split piece of teflon to protect the header from the spring clamp clamp</DIV>
<DIV>?</DIV>
<DIV>Is there a certain type of teflon with higher abrasion resistance that what I am using? Is the colored teflon weaker than the standard milky-white teflon? Anybody else suffer from this problem? Thanks.</DIV><BR><BR>Bob Kane<br>getterflash at yahoo.com<p><hr SIZE=1>
