The S‑LOK Plug & Cap series provides a secure solution for sealing and plugging tubing systems. Manufactured from 316 stainless steel with a robust double-ferrule compression mechanism, these fittings deliver outstanding leak resistance and durability.
Available in a wide range of sizes — from 1/16″ to 2″ (or metric equivalents) — the plugs (SP-series) and caps (SC/SCO-series) support both tubing and port sealing applications. Installation is simple: finger-tighten the nut, then add ¾-turn on smaller sizes, ensuring a secure seal without the need for wrenches .
These fittings are reusable, allowing easy maintenance and reconfiguration. With compatibility across major brands like Swagelok® and Parker® A‑LOK®, inventory can be streamlined.
As the authorized distributor of S‑LOK in Vietnam, SK Tech offers these components in full range, with technical guidance and support for critical fluid systems.
