Enter the converter washer. Unlike a standard flat washer, which is primarily used to distribute load or prevent surface damage, a converter washer is an engineered adapter. It is typically a machined metal ring with specific geometry designed to mate with two different standards simultaneously. For instance, when converting between BSP and NPT, the washer often features a 30-degree seat (common in European fittings) on one side to interface with the BSP fitting, and a different seating angle or profile on the other side to mate with the NPT port. By sitting between the male fitting and the female port, the washer allows the two incompatible parts to screw together and form a tight, high-pressure seal without metal-to-metal grinding or thread destruction.
