Heater Pressure Switch Hole Plug 1/8 Inch NPT

Heater pressure switch hole plug is 1/8 inch NPT plug used to close off the unused pressure switch hole/tap of a spa heater. 

This is usually only needed if the pressure switch is mounted external to the heater. 

Pressure switches should never be bypassed when operating a spa for safety reasons - but if the function is covered elsewhere in the spa plumbing, then this plug will cover the hole in the heater meant for a pressure switch.
