Gr8LOK 8045 Mech Tee - BSP Outlet

The Mechanical Tee with Screwed Outlet is a versatile branch fitting designed to create a threaded connection directly from an existing pipe without the need to install a full tee. Ideal for fire protection, HVAC, and mechanical services, it provides a fast and efficient method of adding smaller branch lines to grooved piping systems.

 
Manufactured from durable ductile iron, the mechanical tee is secured to the pipe using a bolted housing and gasket arrangement, forming a reliable, pressure-responsive seal. A hole is cut into the pipe to create the outlet, allowing installation without removing or replacing pipe sections—making it particularly suitable for retrofit work, system extensions, and on-site modifications.

 
Supplied with a screwed (BSP threaded) outlet, this fitting is ideal for connecting ancillary services such as drains, gauges, test points, and small-bore pipework while maintaining full compatibility with grooved pipe systems.

 
Key Features

• Mechanical tee design – allows branch connections without cutting out pipe sections 
• Screwed (BSP) outlet connection for small-bore threaded applications
• Suitable for a wide range of pipe sizes (typically up to 200mm systems depending on variant)
• Ductile iron construction for high strength and durability
• Grooved clamp-on installation using bolted housing and gasket system
• EPDM gasket sealing system for pressure-responsive leak resistance
• No hot works required, improving safety and installation speed
• Compatible with standard grooved pipe systems
• Ideal for retrofit and system modification work

 
Applications

• Fire sprinkler systems (drain points, test valves, gauge connections) 
• HVAC and chilled water systems
• Mechanical and industrial pipework
• System extensions and live pipe modifications

 
Designed for flexibility and speed, the mechanical tee with screwed outlet provides a reliable method of adding threaded branch connections while minimising disruption to existing pipework systems.
