2025 UPDATE​

COUNTERFEIT WARNING – –

The rapid growth of e-commerce has created opportunity for domestic and international sellers to offer counterfeit products in the market. We have found counterfeit Melling products on multiple online marketplaces. These sellers have become very creative in closely duplicating our box design and including our registered trademark and identification marks on the casting. Sadly, consumers purchase believing it is an authentic quality Melling manufactured part but receive an inferior, non-genuine product. We are monitoring these online platforms and will be taking legal action.
