Is the QC-LOK® stainless steel QC4 bulkhead socket with tube connection compatible with standard instrumentation quick couplings from other manufacturers?

Yes. The QC-LOK® stainless steel QC4 bulkhead socket with tube connection is fully interchangeable with standard instrumentation quick couplings from other manufacturers, ensuring easy integration and maximum flexibility while maintaining leak-tight performance, high working pressure, and chemical resistance.

Is the QC-LOK® stainless steel QC4 bulkhead socket with tube connection suitable for use in medical and pharmaceutical environments requiring biocompatible, corrosion-resistant materials?

Yes. The QC-LOK® stainless steel QC4 bulkhead socket with tube connection is suitable for medical and pharmaceutical environments that require biocompatible, corrosion-resistant materials. It is manufactured from AISI 316 stainless steel, a material widely accepted for medical and pharmaceutical use due to its excellent corrosion resistance and biocompatibility. The unit is factory-tested for absolute leak-tightness at 68 bar and rated for working pressures up to 206 bar, ensuring reliable, safe performance in critical applications. The Viton sealing system provides strong chemical resistance and durability across a broad temperature range (-26°C to +204°C), supporting compatibility with many process fluids and cleaning agents used in medical and pharmaceutical settings. Additionally, its proven design, interchangeability with standard instrumentation quick couplings, and suitability for laboratory and pharmaceutical production environments further support its appropriateness for these sectors.
