ISO Crosses
ISO-K 4-way, 5-way and 6-way crosses
All ports on a standard ISO cross share one flange size. The ISO 4-way cross is the most common layout, built around a main tube with two side ports for gauges, valves, feedthroughs, or further tubing. A 5-way or 6-way cross adds ports on the remaining axes, so one fitting can serve as a small chamber or manifold.
- ISO-K 4-Way Cross: ISO 63, 80, 100, 160, 200, 250, 320 and 400
- ISO-K 5-Way Cross: ISO 63 to ISO 250
- ISO-K 6-Way Cross: ISO 63 to ISO 250
ISO reducer crosses and ISO-to-KF reducer crosses
A reducer cross changes size at the junction so a larger line can branch to smaller instrument ports without separate adapters. The ISO-K Reducer Cross keeps all four ports in the ISO family. The ISO-K to KF (ISO-QF) Reducer Cross runs an ISO 63, 80, or 100 line with a KF40 or KF50 branch, combining an ISO-to-KF adapter and a junction in one part. For full KF layouts, see KF Crosses.
Complete the ISO connection
Each port on an ISO-K cross needs a centering ring, O-ring, and clamps. Order claw clamps and bolt rings from ISO Clamps & Fasteners and centering rings and O-rings from ISO Hardware & Seals.
