ISO-K Straight Reducer 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.

ISO Nipples Feature:

  • Half nipples feature one ISO flange
  • Full nipples feature two ISO flanges
  • Conical and straight reducer nipples adapt two different flange sizes
  • Common lengths and tube diameters listed; contact us with your specific requirements
