Jim Doster –
Terrific Product!!! We live in the Inner-City and are Black. Some neighbors put water down our oil fill pipe – cost the Landlord $$$thousands$$$ to pump out the tank, fix the furnace, not to mention we had no heat. This little device foiled the bigots from trying to run us out. The Landlord installed this cap on the oil fill pipe and we put OUR padlock on it – we’ve been warm ever since.

After installing on my oil tank for the heater it began rusting by the next day. Spray painted and good for now, but will need to continue to check for corrosion.

This cap slowed down the thief enough for me to catch him and tune him up, needles to say he will not be back.
