Precision stainlesssteel plug designed for reliable sealing of oil and water pipe systems. This malethread hex socket end cap (inner hexagon plug) is made from 304 stainless steel and uses BSPT threading for secure, leakresistant connections in compatible ports. Key benefits Durable corrosion resistance: 304 stainless steel resists rust and corrosion in wet and oily environments, extending service life. Positive, toolready sealing: internal hexagon (hex socket) allows easy installation and removal with a matching hex key (Allen wrench), giving reliable torque control for a tight seal. Simple compatibility: male BSPT thread mates with corresponding female BSPT ports to close off unused lines or ports quickly and cleanly. Reduces leaks and contamination: provides a robust end cap to prevent fluid loss and ingress of contaminants during operation or maintenance. Main attributes Thread type: BSPT (British Standard Pipe Taper) male thread for tapered, pressuretight engagement with BSPT female fittings. Size: 1I8 inch BSPT thread (as specified). Material: 304 stainless steel for strength and corrosion resistance. Design: hex socket (inner hexagon) end cap / plug for toolassisted installation. Function: seals the end of oil and water pipe fittings and ports to prevent flow or contamination. How it solves problems Stops drips and reduces downtime by providing a reliable, threaded closure for unused or temporary ports. Replaces damaged or missing end caps with a corrosionresistant, serviceable part that can be tightened or removed without damaging adjacent fittings. Fits confined spaces where an internal hex drive is preferable to external wrenching, reducing the risk of rounding edges. Typical applications Plumbing and fluid lines: close off 1I8 inch BSPT ports on oil and water piping systems during testing, commissioning, or permanent installation. Equipment and machinery: seal spare or unused BSPT ports on pumps, valves, manifolds, and hydraulic units to prevent leaks and contamination. Maintenance and service operations: provide a temporary, toolremovable seal during work or system flushing. Installation and care Install using a properly sized hex key (Allen wrench) engaging the internal hexagon. Apply controlled torque to achieve a secure seal. Ensure mating BSPT female threads are clean and undamaged before installation. For sealing practice, use appropriate thread sealant or tape compatible with system fluids if required by the application or site standards. Inspect periodically for wear or corrosion and if threads or sealing surfaces are compromised. Compatibility and performance notes Designed specifically for BSPT female threaded ports of the specified 1I8 inch size. Confirm thread type and size before . 304 stainless steel offers general corrosion resistance suitable for water and many oils; verify chemical compatibility with aggressive fluids or specialized environments. Built for dependable, lowprofile sealing where a compact, hexsocketdriven male BSPT plug is required.
