Adapters

High-pressure adapters and inserts for connecting different tube sizes, male and female ends or pressure classes in a waterjet circuit.

Adapters solve the connections that a straight coupling cannot: 1/4" to 3/8", male to female, or a fitting on the pump to the line that leaves it. Because they sit between two standards, they are also where mistakes happen, so check both ends before ordering.

For each end we need the size, whether it is male or female, and the pressure class. The reference printed on the old adapter, or a photo showing both ends, is usually enough to identify it.
