NBR/EPDM/FKM O-rings for a NZ dairy maintenance supplier

A Waikato dairy equipment maintenance company was buying spare seals through local industrial distributors at trade prices that added up on a running maintenance budget.

The order

3,000 pieces per year of mixed O-rings (NBR, EPDM, FKM compounds), FDA food-grade, for milking equipment and heat exchanger maintenance. 24 sizes in one annual contract.

What mattered. This wasn't about finding the cheapest O-ring — it was about consolidating 24 sizes from three Chinese Ningbo seal factories into one shipment, with material test reports (FDA food contact certification) for each compound. We audited one factory, negotiated per-size pricing, and arranged quarterly air-freight restocks so the client doesn't hold dead inventory.
