Industrial weld and braze fittings are designed for joining tubing or pipe to other components in fluid or gas systems, especially in applications having high or dynamic pressure, temperatures high vibrations or in systems where safety requires permanent leak tight connections. Because of the permanent nature of the seal, weld and braze adapters are frequently used in hydraulic systems with extremely high operating pressures and/or vibration.

Weld and braze adapters join tubing or pipe to the adapter by butting the material to the fitting or by inserting the tubing or pipe into a socket in the fitting. Only Type 316L stainless steel should be specified for weld & braze adapters. This low carbon stainless steel (denoted by the suffix “L”) minimizes post-welding corrosion called intergranular corrosion.
