They are inexpensive caps about an inch long apparently of the same
material as the Phillystran jacket. I give then a shot of Silastic RTV
(TM0and install with a twisting motion that leaves a small ridge at the
end of the cap. I advise waiting for the material to cure before
installing the Phillystran, although rain will speed the cure. Just keep
it out of the Phillystran. I've had some up over 10 years and they are
like new

There are ends made for sealing (DX Engineering and others have them).
I just put some caulk in the cap and push it on the end of the
Phillystran. The caps are about 0.25USD or so a piece. No problem in
10 years so far.

Subject: [TowerTalk] Sealing Ends of Phillystran HPTG-1200
I just finished assembling my M2 40M4LLDD 40 meter Yagi. The element
supports use Phillystran HPTG-1200.. I've heard that the inner fiber core
of Phillystran is highly affected by water intrusion, but the manual
makes
no mention of sealing or capping the ends of the Phillystran.
Do I need to seal or cap the ends to protect against water intrusion? If
so, what is the preferred way to do this?
Thank you,
J D Lambright - KF5U
