Swagelok SS-QC4-BPK8 Stainless Body Protector Fitting

SS-QC4-BPK8 is a stainless steel body protector for Swagelok QC4 instrument quick-connect fittings in a 6 mm size. As a Body Protector (BP) variant in Swagelok’s QC4 family, it is designed to shield the connector body from damage and contamination during mating, handling, and routine maintenance without altering the fitting’s seal geometry. The SS prefix confirms a stainless steel construction, suitable for typical laboratory and process environments where corrosion resistance is important. This protector specifically complements 6 mm QC4 quick-connects, enabling protection in compact instrumentation lines and test setups that rely on fast, reliable connections. The BPK8 designation identifies a particular protector variant within the QC4 lineup, aligning with Swagelok’s standard body protector nomenclature. By pairing the QC4 body protector with the corresponding quick-connect, technicians can safeguard the exposed body in tight spaces and during frequent connection cycles, helping to maintain consistent performance of the mating interface in instrumentation and analytical systems.
