Replacing Rubber Ware

Of all the rubber parts in a dairy production operation, milking inflations, or liners, receive the majority of wear and tear. The rhythmic flexing action during milking eventually causes miniscule fissures which, over time, develop into cracks and holes. Since these cracks can not be properly cleaned of milk residue, inflations must be inspected on a regular basis and replaced when such defects are found.

Typically rubber inflations may last from 1200 to 1500 milkings, while silicone inflations are designed for 6500 milkings each. However, to be sure, check the manufacturers' recommendations.

Here is a simple formula you can use to calculate how often your inflations should be replaced.

Example: 3 milking units used on 60 goats

(60 goats ÷ 3 units) X 2 milkings per day = each unit performs 40 milkings per day

inflation designed for 1200 milkings ÷ 40 milkings per day = inflation change required every 30 days

As well, all other rubber parts including milk hoses, gaskets, and plugs should be inspected frequently. All rubber parts should be replaced at least annually. Excessive use of chlorine will cause premature failure of the rubber parts and causes the black rubber "inking- off" on your hand when parts are inspected or handled. Inspect your equipment for rubber wear on a regular basis. Replace worn parts when necessary in order to optimize milk quality.
