Features: Pressure rating 0-10 bar. Temperature rating 0-120°C. Standard thread sizes available: 1/8-inch, 1/4-inch. Suitable for floor heating systems. During installation, do not manually twist the header or straight-line wire. The pressure gauge, thread, and dial are aligned in a straight line. Avoid pulling by hand or rotating the header, as uneven force may cause deformation of the pressure gauge structure, damage internal components, or impair functionality. Use an external wrench for installation.
