Threaded Fittings and Accessories

Adapters and fittings of different connections and sizes to connect to any type of thread or endings. We have mixed adapters that can match different standards, for example, a connection that is American NPT thread on one end and European BSP thread on the other.

We have a large warehouse and stock to deliver the same day.

If we do not have it in stock, we can produce high-quality accessories in our state-of-the-art manufacturing facilities and provide immediate technical support.

They are typically used for hydraulics or pneumatics but can be used for construction, mining / aggregates, pulp and paper, agriculture, manufacturing, industrial, marine, aerospace, military, OEM among others.
