304 stainless steel (304SS) male-thread end cap plugs with hexagon socket screw, available in PT/NPT sizes 1/16, 1/8, 1/4, 3/8, 1/2, 3/4, 1, 1 1/4, 1 1/2, and 2 inch. Key benefits - Secure, leak-minimizing seal: these end cap plugs close off pipe ends and threaded ports to prevent fluid or gas leaks and contamination. - Durable corrosion resistance: 304SS construction resists rust and general corrosion for long service life in many industrial and maintenance environments. - Compact, reliable drive: internal hexagon socket screw allows positive engagement with an Allen key for reliable tightening and easy removal in confined spaces. - Broad compatibility: available across a wide range of PT/NPT male thread sizes to match common piping and instrumentation threads. - Thread and port protection: protects internal or external threads from damage during storage, transport, and assembly. Key features - Material: 304 stainless steel (304SS). - Drive type: hexagon (internal hex) socket screw. - Thread types: PT/NPT male threads. - Available sizes: 1/16", 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1 1/4", 1 1/2", 2". - Function: acts as an end cap plug for pipe ends and threaded ports. Performance and practical notes - Use appropriate thread sealant or tape when a pressure-tight seal is required; hex socket drive provides controlled torque for consistent compression. - 304SS offers good mechanical strength and chemical resistance for many applications; select material and sealing method appropriate to media and temperature. - Installation and removal are straightforward with standard hex keys; internal socket reduces snagging and preserves clearances on assemblies. Typical applications / use scenarios 1. Maintenance and commissioning: temporarily cap off instrument ports, valves, or piping during system pressure testing, leak checks, or equipment commissioning to prevent contamination and control leaks. 2. Process and utilities: permanently or semi-permanently close unused branch lines, sample points, or service connections in pneumatic, hydraulic, water, and low-corrosivity process systems. 3. Fabrication and storage: protect male threads on pipe spools, fittings, or assemblies during transport and storage to avoid thread damage and contamination before installation. Installation tips - Match plug size to the PT or NPT male thread on the piping or fitting. - Use the correct hex key size and apply steady torque; avoid over-tightening to prevent galling or thread damage. - For pressure-containing service, apply recommended thread sealant or PTFE tape per system requirements. - Inspect threads and sealing surfaces for debris or damage prior to installation. This 304SS hexagon socket screw end cap plug range provides a straightforward, durable solution for sealing and protecting PT/NPT male-threaded pipe ends and ports across a wide range of common sizes.
