Abstract: New splined fluid ports and caps for fluid ports are provided. The fluid ports and caps are straightforward in construction, are easy to manufacture and use, and are structured to be highly effective and reliable in use. The present fluid ports and caps, for example, dust caps structured to be secured to luer ports, include coupling systems, for example, including pluralities of splines and spaced apart thread segments, which provide benefits, for example, in terms of reduced manufacturing costs and ease of manufacture, relative to prior art such parts which are fully threaded to provide for coupling.
