ISO-K Half Nipples

We fabricate these ISO nipples (spools) for HV systems from 304L stainless steel tubing and ISO flanges. The ISO flange (also called Large ISO) is used for HV chamber ports and is available in two distinct styles; ISO-K which uses clamp fasteners and ISO-F which uses nut and bolt fasteners.
