Underground Storage Plug Safe 6-Inch

Underground Storage Plug Safe 6-Inch

This Underground Storage Plug Safe 6-Inch with Pipe Plug provides nearly everything you need for making an 6-inch Cache Tube. All you need is 6-inch D-3034 Sewer pipe and PVC primer and glue.  This kit is ideal for customers that already have access to the required pipe and the PVC (primer and glue).  This eliminates shipping heavy pipe and declaring toxic materials.


A sample of 6-inch D-3034 Sewer Pipe is in the kit for unmistakable selection of pipe from a local pipe supplier. Many pipe suppliers and many construction sites may have damaged 6-inch ASTM D-3034 Sewer Pipe available at no cost.  We also offer a SHTF Cache 6-Inch x 2 Feet Long that includes 2-feet of pipe.

Kit Contents

This Underground Storage Plug Safe 6-Inch includes two 6-inch caps.  One is solvent weld onto sewer pipe forming the bottom of the cache tube.  The other cap is to cover the tube end.  In the kit is a 6-Inch Gripper Plug to seal the end of the cache tube to keep out moisture.


A “Gripper” Internal Plug is provided in this kit instead of an End Plug as the end plug wing nuts on the End Plug will interfere with pipe caps with the potential of cracking the cap.   Internal plugs provide flexibility on position and can be adjusted to provide space for silica gel packets to absorb moisture that might accumulate in the cap area.

This Underground Storage Plug Safe 6-Inch includes 20-feet of 550 parachute cord for lowering the cache tube into a hole, and 100-feet of pipe wrap tape to protect the tube and to ensure the joints are sealed.  This tape is made for underground applications with long life in a moisture environment.

Owners Manual

The kit includes a comprehensive owners manual with information on digging cache tube holes, assembly  of cache tubes, and a discussion on protecting contents.  This is not an ordinary assembly document but a well written document with good photographs.


The Holey-Moley Digger web site has a number of YouTube Public Instructional Videos with lots of good information.  There are also a number of Private Videos available for those that purchase products.
