Great design, sturdy build
Appears to be well made, and well-designed. Front cover is easily removable, and adjustment instructions are good, even has a locking plate to hold the pressure screws in place. Electrical contacts easy-to-access. Removed one star because there's no description when you buy it off of what the connection is. It appears to be a 3/8 flare connection. Haven't used it yet, if it does not function as it should I will update this review.

La identification de la caja no concuerdo con el presostato que trae.
He comprado dos de estos presostatos, con el rango de 7 psi a 87 psi , y cuando abro la caja el presostato va de 100 a 465 psi. No.me sirve para nada
