We provide best quality products


The supply of best quality spare parts is essential to have efficient engines and keep maximun productivity

In every industrial sector and in every mechanical application it is demonstrated that the gaskets are used at the most critical point of the plant; we therefore consider it indisputable to save on the quality of materials when the criticality of the application can seriously lose functionality for a mere economic purpose.

It is our practice to verify that all individual items entering the warehouse must comply with production and testing procedures typical of OEM supplies.

Most gaskets are ordered in annual or semi-annual quantities to get the best prices and to ensure constant availability for the parts you need.

As part of an important qualitative offer, the packaging and shipping phase is important; a careful choice of the type of packaging is the guarantee of the integrity of the supply up to its use.
