These pressure die-cast aluminum tank heaters are designed to circulate coolant through engines ranging in size from 650 CID (Outside installation) to 1200 CID (for engines inside an insulated building).
These heaters are designed for hard-wire electrical connection using rigid or flexible conduit.


We recommend hose barbs for easier installation:
Part # HB3/4 for use with 3/4" I.D. heater hose. Part # HB1 for use with 1" heater hose. You may want TWO - 1 each for the inlet & outlet.

Hose barbs are solid aluminum hose nipples that thread into the heater inlet and outlet.

Many other sizes and wattages are available, just ask!
