For fitting, a section of the fitting is pushed into an aperture (5), and sealed with a lip seal (6). The part of the section behind the seal has a peripheral projecting surface with a smooth area formed on a ring shoulder. The surface may be angled or interrupted. The fitting is a rose fitting around another part (1), e.g. base.
