The Beaded Plug is a type of pipe fitting designed to securely seal the end of a threaded pipe. Made from high-quality malleable cast iron, it features a beaded rim for enhanced strength and a tighter grip during installation. Available in both galvanized and black finishes, this plug is corrosion-resistant and suitable for high-pressure plumbing systems. It complies with standards such as EN10242 and ISO 7-1, ensuring durability and reliability in water, gas, and fire protection systems.

The 80mm 3" GI Beaded Plug BSP End Cap is a specialized pipe fitting engineered to securely seal the end of 80mm (3") threaded pipes in plumbing, fire protection, and industrial systems. Crafted from high-grade galvanized malleable iron, this BSP end cap features a unique beaded rim design that enhances structural strength and prevents loosening— a critical improvement over standard smooth-rim caps, which can shift from vibration or pressure changes. As a GI beaded plug, it prioritizes leak-proof sealing, making it ideal for closing unused pipe ends, protecting systems during maintenance, or terminating lines in closed-loop setups. Its galvanized finish adds corrosion resistance, making it suitable for damp environments (e.g., basements, outdoor piping) where non-protected end caps would rust.
The beaded rim of this end cap creates a mechanical lock against the pipe’s end, ensuring a tight, long-lasting seal. This design eliminates leaks that plague smooth-rim caps, making the beaded rim pipe cap ideal for high-pressure systems like fire sprinklers or industrial pipelines.
Coated with hot-dip galvanized or electro-galvanized zinc, the 80mm GI beaded plug resists rust, oxidation, and chemical damage. This protection makes it suitable for outdoor, underground, or high-moisture environments— such as irrigation systems, water treatment plants, or crawl space plumbing.
Built from malleable cast iron (compliant with EN 10242 standards), the end cap withstands impact, pressure, and temperature fluctuations. Unlike brittle cast iron alternatives, the malleable iron end cap remains ductile, reducing the risk of cracking during installation or use.
Designed with BSP threads (British Standard Pipe), the 3" BSP end cap ensures seamless compatibility with BSP-threaded pipes worldwide. This standardization simplifies installation, reduces mismatching risks, and ensures a secure seal in closed-loop systems.
Available in galvanized (for corrosive settings) or natural black (for low-moisture interiors) finishes, the beaded plug adapts to diverse applications— from residential plumbing to industrial process piping. Its FM/UL/CE certifications further validate its use in high-stakes systems like fire protection.

In homes, offices, or apartments, the plumbing end cap seals unused pipe ends (e.g., after fixture removal or system upgrades). It prevents water leaks, contamination, and debris entry, maintaining water quality and system efficiency. The galvanized finish is ideal for cold/hot water lines with constant moisture.
Certified by FM and UL, the fire protection end cap seals branch lines or unused sections in fire sprinkler systems during installation or maintenance. It preserves water pressure, ensuring the system activates quickly in emergencies and meets building safety codes.
In factories or processing plants, the industrial pipe plug caps pipes during downtime, maintenance, or testing. It prevents dust, debris, or foreign materials from entering the system, protecting sensitive equipment like pumps, valves, or meters.
Heating, ventilation, and air conditioning systems use the HVAC end seal to close unused pipe ends in chilled water lines or hot air ducts. The tight BSP thread seal reduces energy waste from pressure loss and prevents condensation-related corrosion.
