Geocache Maintenance: Bison Tube O-Ring Replacement

Geocaching Bison Tubes

Many geocachers know that geocache maintenance is extremely important when it comes to the continual fun and overall satisfaction of the geocaching experience.

Why you may ask?

Debate-ably if a geocache owner takes responsibility for their geocache hides and checks on them on a regular basis then this can improve the chances that a geocache is in the best condition possible. For example, bison tubes. Those crafty micro geocaches have been a staple and bane of geocachers for many years. The biggest complaint is usually a soggy log book and we know what the main cause is. Bad o-rings.

Bison Tube O-Rings

The one part of a bison tube that requires maintenance is the o-ring which helps seal the cap from the body. Because of age and the influence of the outside elements, the o-rings become brittle and fail. This then allows a better chance for moisture to enter and play havoc on the log.

So it is highly recommended as part of your geocaching maintenance to check and if necessary replace the bison tube o-rings. This will help in avoiding a log book of goo and keep our fellow geocachers happy.

By the way this is a random website I found that sells bison tube o-ring replacements:

Your local hardware store sells these o-rings in the plumbing dept. for around $2 dozen. Keep them with you and replace them as you find them when hunting!

One dab of Dow Corning High Temp Vacuum grease and that O-ring will outlive the tube.

From the sales blurb, Dow Corning High Vacuum Grease is a stiff, nonmelting silicone lubricating material and has much higher stability at the higher end of the temperature range(-40° C to 200° C). Dow Corning High Vacuum Grease is also used to lubricate synthetic and silicone rubber gaskets being used in high temperature applications.

Vaseline gunks up and dries out. This stuff will not.

professorbensen - they derive the name from Bison Designs - one of the main companies that was making them when they first caught on as Geocaches.
