Pressostat Tecmark 3902
Description du produit
Pressure switch - Manufactured by Tecmark 3902 - 3903 is 3902 with screws. 1/8 inch MPT screw thread to attach to heater tube. Switching mechanism tabs at the sides
are 2 x flat spade connectors to attach the contact wire. Height: 58 mm Width: 50 mm.
It sometimes varies in appearance and the later ones are smaller, red with a black underbelly. They do have a PSI gauge on the side but we would not usually recommend adjusting this, or if you do, do it very gradually. Most of the time you can tell if the pressure switch is seized because the small bearing inside will not rattle anymore.
