Pipe Thread Seal Tape for Grip Screw Cap

I claim no originality for this idea, but my wife and I have found that pipe thread seal tape helps to prevent grip screw caps on our tenkara rods from working loose. Some rods are worse about this than others, but it’s not uncommon to have the grip screw cap on a tenkara or keiryu rod work loose and drop off in the water while you’re fishing. Can there be anything more frustrating than finishing a morning’s fishing only to discover that part of your rod is now floating down the creek?

Please understand that this is not a cure-all, and you’ll have to use your own judgment on this, but we’ve found that a turn or two of the seal tape (available at any hardware store) helps to keep the grip screw cap from working loose. Of course, you still want to finger-tighten the cap from time to time just to be safe. See the accompanying photo for an example.

Hope this helps others! Again, I’m sure other people have already used this idea.

I Put a Cork In It
by: Herb S.

Good idea, John! Not long after I received my first tenkara rod, a 12' Iwana from TUSA, the cap fell off and was lost. Bummer! So I took the rod down to a real hardware store(rapidly vanishing due to big box stores) and fitted a cork and a spare. It worked. Eventually I called TUSA to order a new cap and was told that others used a small rubber o-ring to solve the problem. Back to the hardware store. It seems to work, too, and better.

By the way, none of the 5 keiryu rods nor the 1 seiru rod bought from Chris have had this problem. I do check out of habit while fishing, but have never found a loose cap.

Some Additional Thoughts on Thread Tape
by: John Evans

Herb,
Thanks for your comments and sharing of experience. I would add a couple of points to my original article. One: don't put on more tape than needed. I always worried about distorting the threads on the cap or damaging the carbon fiber handle, so I just use a couple of turns of the tape. So far, in a couple of years, I've had no problems. Second: As you suggested, each rod seems to be a law to itself. Some rods almost never have this problem, while other rods seem plagued by it. Again, finger tighten as you fish (it gets to be a habit), and learn the tendencies of each rod. Some end caps fit snugly from the factory, while others sort of "swim around" in the threads.
