The HAM-LET 3001216 is a compression-style tube plug manufactured from 316 stainless steel and rated for service down to -20 degrees F. It is designed to seal the open end of a compression tube fitting or tubing run, creating a pressure-tight termination without welding or threading. The plug meets multiple ASTM and DIN material standards, confirming consistent alloy composition and mechanical properties. Plumbers, pipefitters, and instrumentation technicians install this fitting in process, hydraulic, and instrumentation tubing systems where a dead-end cap is required.
This compression tube plug is suited for industrial and commercial applications involving tubing systems that carry gases or liquids requiring a clean, leak-free termination. Typical scenarios include capping unused ports on instrumentation manifolds, sealing test points, or closing off branch lines during system modifications. Its stainless steel construction makes it appropriate for corrosive-media environments, offshore installations, and food-grade or pharmaceutical process lines where material traceability to ASTM A182, A213, A269, A276, and A479 is required. The Swagelok-equivalent part number is SS-500-P.
Cross-references to Swagelok part number SS-500-P. Designed as an OEM-style compression tube plug for use with standard compression-style tube fitting systems in instrumentation, process, and industrial tubing applications.
Installation is performed by qualified pipefitters or instrumentation technicians. Depressurize and drain the tubing system fully before installing or removing any compression fitting. Hand-tighten the plug onto the tube end, then advance with a wrench per standard compression fitting make-up practice - do not overtighten. Verify the system is leak-free under working pressure before returning to service.
