The DIN11864-3 is a relatively new fitting for the pharmaceutical processing market. This fitting is gaining interest from process engineers because the seal inside is better to control. The fitting has a compression limiter build in so intrusion of the gasket material inside the pipe is reduced to the absolute minimum.
