Cross 4-way DN160ISO, stainless steel 316L

ISO-K 4-Way Crosspieces – Precision Flow in Every Direction

Our symmetrical ISO-K 4-way crosses are engineered for high-performance vacuum systems requiring multi-directional flow. Each fitting features four flanges and metric bore sizes, making them ideal for complex setups.

Thanks to the pull-port technique, the side ports offer a smooth inner surface, reducing flow resistance and improving conductance. Both the inner and outer surfaces are finished to a high standard, with optional polishing or glass bead blasting available upon request.
