Plumbers, pipefitters, and DIY homeowners who work with BSP pipe systems need a blanking solution that threads on cleanly, holds pressure, and won't corrode over time — especially in damp utility rooms, outdoor irrigation setups, or industrial environments.\u003c\/p\u003e\n\u003cp\u003eThis listing covers two complementary fitting types machined from \u003cstrong\u003e304 stainless steel\u003c\/strong\u003e: a \u003cstrong\u003efemale end cap\u003c\/strong\u003e (threads onto a male BSP pipe end) and a \u003cstrong\u003emale plug\u003c\/strong\u003e (threads into a female BSP port). Both types are available in BSP sizes from \u003cstrong\u003e1\/8\" to 2\"\u003c\/strong\u003e, covering the most common nominal pipe sizes used in residential and light commercial systems. Each piece is sold individually (1 pcs per order) so you can mix and match exactly the sizes you need without buying a kit with sizes you'll never use.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include capping unused tee outlets on water supply manifolds, plugging test ports on compressed air lines, blanking off irrigation zone valves during off-season storage, and sealing hydraulic circuit ports during maintenance.
