Dairymaster Recording jar wash relay spring Dairymaster Recording jar wash relay spring is a vital replacement component for the wash relay mechanism in the recording jar assembly on your Dairymaster milk-meter or metering setup. Over time, the original spring can lose tension or fatigue — affecting the relay’s ability to trigger the automatic cleaning cycle properly. That can lead to incomplete washes, residue build-up or inaccurate milk yield measurement. Replacing the spring is a cost-effective way to restore reliable wash timing and function, helping your engineers keep the metering system spot-on and your dairy operation running smoothly. Designed to meet the dairy-shed environment’s demands, the spring delivers consistent performance under frequent cycle use and cleaning conditions.
