Introduction
4-Way ISO-K HV Crosses are high-vacuum connection components designed to create four-directional branching points within vacuum piping systems. Built with standardized ISO-K clamp flanges, these crosses provide secure sealing, modular expansion capability, and reliable vacuum integrity in medium and high vacuum environments.
ISO-K HV Crosses are widely used in thin film deposition systems, vacuum furnaces, semiconductor manufacturing equipment, and research laboratory vacuum lines where flexible system configuration is essential.
Detailed Description
4-Way ISO-K HV Crosses are typically manufactured from 304L or 316L stainless steel, offering strong mechanical stability, corrosion resistance, and low outgassing properties suitable for high vacuum service.
Key structural features include:
ISO-K clamp flange interfaces for quick installation
Precision-machined sealing surfaces
Smooth internal bore to reduce turbulence and contamination
TIG-welded construction for mechanical integrity
The ISO-K flange system utilizes centering rings with O-rings and external clamps, allowing fast assembly and disassembly while maintaining reliable vacuum performance. Compared with permanently bolted flanges, ISO-K designs significantly reduce maintenance time and improve system flexibility.
These crosses are commonly integrated to connect pumps, gauges, valves, process chambers, or gas inlet lines in complex vacuum networks.
