Plumbers, pipefitters, maintenance technicians, and DIY homeowners working on water supply, compressed air, or gas distribution systems all need a reliable BSP hex end cap that installs quickly and stays sealed for years.\u003c\/p\u003e\n\u003cp\u003eEach piece is a solid 304 stainless steel hex end cap with female BSP threads (internal thread), rated at 150 LB working pressure. The hex body is machined for a clean wrench grip. Sizes are available from BSP 1\/4\" (DN8) through BSP 2\" (DN50), covering the most common residential and light commercial pipe diameters. Thread form follows the BSP standard (ISO 7\/1), ensuring compatibility with standard BSP male-threaded pipe ends and fittings.\u003c\/p\u003e\n\u003cp\u003eTypical applications include capping unused outlets on BSP manifolds, sealing dead-end branches in stainless steel water supply lines, blanking off test points on compressed air systems, and closing pipe ends during pressure testing of plumbing installations. The corrosion-resistant 304 stainless steel construction makes these caps a practical choice for indoor plumbing, light industrial pipework, and food-grade or sanitary installations where carbon steel fittings are unsuitable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔗\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard BSP male-threaded pipe ends and fittings (ISO 7\/1).

BSP sizing is based on the internal diameter of the pipe, not the thread outer diameter. For example, a BSP 1\/2\" cap (DN15) fits a pipe with roughly 15mm (≈5\/8\") internal bore. Always verify the thread size stamped on your existing fitting or pipe before ordering. If in doubt, measure the OD of the male thread and compare to a BSP thread chart.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the pressure rating of these hex end caps?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese fittings are rated at 150 LB, which generally corresponds to approximately 150 PSI working pressure at ambient temperature for water service.

For high-pressure or high-temperature applications, consult a qualified engineer before installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these end caps be used outdoors or in wet environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. 304 stainless steel offers good corrosion resistance in most outdoor and wet environments, including fresh water, mild chemicals, and humid conditions. It is generally suitable for outdoor plumbing and light industrial use. For marine environments or systems with high chloride exposure, 316 stainless steel is typically recommended for better corrosion resistance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these BSP end caps compatible with NPT fittings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. BSP (British Standard Pipe) and NPT (National Pipe Thread) are not interchangeable. BSP threads follow ISO 7\/1 with a 55° thread angle, while NPT uses a 60° thread angle. Mixing the two can result in cross-threading, leaks, or fitting damage. Always confirm your pipe system uses BSP threads before purchasing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need thread sealant when installing these end caps?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eFor a reliable, leak-free seal — especially in liquid or gas service — PTFE tape or a compatible thread sealant compound is generally recommended. Apply sealant to the male threads of the pipe before threading on the cap. Do not over-tighten: hand-tight plus 1–2 turns with a wrench is typically sufficient for most BSP female thread pipe cap installations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat tools do I need to install a hex end cap?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe hexagonal body allows installation with a standard open-end wrench or adjustable wrench — no special tools required.
