Manufacture of Injection Packers

Brass injection packer

The design of the grease nipple type brass packer incorporates a non-return valve in the lower portion of the packer. When the resin has set, the top of the packer simply unscrews. This enables the base to be left in place leaving a small recess which can easily be filled using TamPlug or similar. The hook on type has the non return ball valve located in the head and this can simply be removed enabling the operative to relieve the water pressure within the structure prior to injection.
