Swagelok SS-QC4-E8 PFk1 Quick Connect Fitting

Swagelok SS-QC4-E8 PFk1 Quick Connect Fitting is a stainless‑steel instrumentation quick‑connect body from Swagelok’s QC4 family, built for fast, secure connections in gas and liquid lines used in analytical instruments, test benches, and process systems. The E8 PFk1 designation identifies a specific keyed variant within the QC4 family, ensuring correct mating with its counterpart and reducing the chance of cross‑mating errors in multi‑component assemblies.

As part of the QC4 series, this fitting emphasizes compact construction and reliable performance in demanding environments. The quick‑connect design enables rapid engagement and disconnection, promoting efficient setup and maintenance of instrumentation lines without sacrificing leak integrity. Its stainless‑steel construction provides high strength and corrosion resistance, making it suitable for laboratory research, chemical processing, and field instrumentation where clean, consistent connections are essential.

Typical applications include instrument sample lines, gas delivery and exhaust paths, and interfaces between analytical equipment and process manifolds. By aligning with Swagelok’s standardized QC4 sizing and mating interfaces, the SS-QC4-E8 PFk1 aims to deliver predictable compatibility with other Swagelok components in the same series, supporting robust, repeatable connections in both bench‑top and industrial settings.
