The S‑LOK Tube Union Cross is engineered for precise, robust 4‑port fluid connections, ideal in instrumentation, process control, chemical, petrochemical, and power systems. Constructed from 316 stainless steel, these fittings incorporate a double‑ferrule compression mechanism to ensure reliable sealing and high-pressure resistance.
Available in tube sizes from 1/16″ to 1″ OD, these crosses are also offered in brass variants. The assembly is simple and tool-free: insert tubing, finger-tighten the nut, then add a ¾-turn on smaller sizes to secure the seal. They can be used repeatedly without compromising sealing integrity—perfect for field maintenance .
These fittings are fully interchangeable with industry-standard Swagelok and Parker A‑LOK systems, reducing inventory complexity.
As the authorized S‑LOK distributor in Vietnam, SK Tech offers these union crosses with full technical support, sizing guidance, and after-sales service for critical fluid and gas systems.
