Their PET turret style case provides superior impact strength and chemical resistance, ideal for chemical and petrochemical processing. Available dry, dampened, or liquid filled, with options for field filling using a liquid fill kit or EZ Fill design. Ranging from 30" Hg vacuum to 11600 psi, these SOLFRUNT gauges are versatile.
