Constructed of recycled composite glass-filled polymer which is stronger than steel pound for pound, the 100mm well plug is designed for years of worry-free use. The wing nut design with a recessed grip allows a padlock (not included) to be easily installed. The 100mm well plug has a tethering attachment at the base for use with a variety of instruments, features no metal parts, and can be disassembled for easy decontamination.

The standard well plug and GasCap is available for 100mm wells.
