Champion Z5941 Automatic Drain Repair Kit

The Champion Z-TD-1 Automatic Drain Repair Kit, Part # Z5941 (R15, R30, R40A, R70A) is a targeted rebuild kit for the Champion Z-TD-1 automatic tank drain valve, the component that removes condensate from the air compressor tank without manual draining, helping prevent moisture carryover into the system. The eight included parts—TD-9 Diaphragm; TD-16 O-ring; TD-7 Valve stem; TD-3 Valve disc; TD-18 Disc backup washer; M2932 Hex brass nut; P1882A Valve Spring; and TD-17 Gasket—cover the critical seals, moving surfaces, and springs necessary to restore proper valve actuation, seal integrity, and reliable cycling after wear or corrosion. As a complete repair kit, it is intended specifically for Z-TD-1 automatic drain assemblies on Champion air compressors and is marketed as a turnkey solution to restore automatic drainage performance, reducing condensate buildup in the tank and helping maintain compressor efficiency and longevity.
