Hydroscand supplys a wide assortment of ORFS adaptors (joints) for different purposes, with several types of threads, like G-, NPT-, M-, UNF-.
Our ORFS fittings are equivalent to SAE J1453 and ISO 8434-3.The fittings handle high pressure up to 63.0 MPa, with a safety factor of 4:1. They are also resistant to vibrations and system impulses. The sealing between pipe and adapter is created by a O-ring, which gives a safe unit. The fitting can be dismantled and assembled multiple times without deterioration of the unit. The only thing that needs to be changed is the O-ring. Compared to other types of steel pipe fittings, the ORFS fitting is very resistant to over-torque. This makes a correct assembling easier, even for untrained persons. By changing the clamping sleeve, the fitting can be used for both metric and inch pipes.
The ORFS fitting part number consists of two parts. The first four digits signify the type (compare with the flare fittings). The four last digits signify the recommended pipe size in inches. 1/4" for example, gives part number 04. For deviating connections, the thread size is given in the part number, for example G 3/8" = 06.
