Generic 40 MFD Run Capacitor [370v] (35-249-1000) prostar A sight glass is useful

A sight glass is useful because it gives the user a direct way to observe water condition during certain valve functions without opening the system

Matching the correct heater-family switch helps preserve intended fit and cleaner control restoration

Helps restore both cover and frame together

The V34-131 is a practical service part when a DE filter repair calls for the right 2 inch directional fitting rather than a close-enough substitute

Generic 40 MFD Run Capacitor [370v] (35-249-1000) prostar A sight glass is usefulA run capacitor helps support normal motor operation in a compatible electrical system, and this generic version is rated at 40 MFD and 370 volts using the 35 249 1000 reference. When a run capacitor becomes weak, swollen, or open, the connected motor can lose the smooth operating characteristics it should provide. The 40 MFD value gives this part practical value because motor capacitors work best when the replacement matches the intended capacitance
