Weathermatic 110-003SA Replacement 1-inch Diaphragm for Silver Bullet

Replace worn or damaged diaphragms with the OEM Weathermatic 110-003SA diaphragm—designed specifically for original Silver Bullet 12024E-10 (SB-10) valves. This service part restores proper valve seating and reliable flow control for older Silver Bullet models.

• Compatibility: Fits original Silver Bullet 12024E-10 (old-style SB-10) valves and 12000 series 1" models.
• Size: 1-inch diameter diaphragm (J part for older Silver Bullet valves).
• Material: EPDM diaphragm material for chemical and chlorine resistance.
• OEM quality: Genuine Weathermatic repair part engineered to original specifications.
• Easy replacement: Swap the diaphragm during routine valve service; no special tools required.
• Note: Not compatible with newer Silver Bullet "HP"/new-series valves (use 110-603SA for new series).

Order the 110-003SA if you maintain legacy Silver Bullet valves to extend service life and reduce leaks. Install by shutting off water, removing the cover bolts, replacing the diaphragm, and reassembling; test the valve before returning to service.
