High Temperature Peep Sites

HIGH TEMPERATURE PEEP SITES

The Tate-Jones Hi-Temp Peep Sites have standard NPT male pipe threads.

The housing of the units is available in stainless steel or carbon steel with nickel plating.

Each unit is carefully assembled with a quartz lens and grafoil gaskets.

The quartz lens is suited for a maximum intermittent operating temperature of 2048°F and continuous operating temperature of 1600°F, and allows for optical pyrometer checking of the flame or operation of vessel.

The lens can easily be removed for cleaning or replacement.

Standard stocked units range in size from 1/2" to 2".

Operating environment and temperature should be considered when ordering.
