Wearing Out Deadmans Rubber Blocks?
Anyone have a better way to shut off the sand blaster deadman control than using that silly little rubber block that wears clean through in no time thanks

Maybe a ball valve,but it too would eventually wear out.

They last a lot longer if you open and shut the valve quickly, let it snap shut. Don't feather the valve, or leave it in a partially open position, this lets abrasive flow over the rubber, wearing it out...Same goes for a ball valve.
But yes, anything in contact with abrasives under pressure will wear out. Later, mikey
