Description
Overview:
The Malleable Iron Reducing Hex Nipple 3" x 2" M/M BSP is a tough, metal pipe fitting used to join two female-threaded components of different sizes on the same line. Made from malleable iron for strength and impact resistance, it is suitable for general plumbing, industrial, and maintenance work where a reliable reduction is needed. The hexagonal centre allows a firm grip with a spanner for straightforward tightening and removal, even in tight spaces. Both ends carry BSP (British Standard Pipe) male threads for broad compatibility across common pipework and equipment such as pumps, valves, tanks, manifolds, and plant services. Size: 3 inch (76.2 mm) to 2 inch (50.8 mm). Manufacturer Part Number: 585 302. Use with appropriate thread sealant for a secure, leak-resistant joint.
Key Features:
- Reduces from 3 in (76.2 mm) to 2 in (50.8 mm) in one compact fitting
- Male/Male BSP threads for easy connection to standard BSP female fittings and ports
- Hexagonal body for positive spanner grip and controlled torque during installation
- Malleable iron construction for durability and resistance to vibration and mechanical shock
- Clean, machined threads help achieve a dependable seal with PTFE tape or pipe jointing compound
- Suitable for water lines, heating circuits, irrigation systems, and general industrial services with non-corrosive media
- Simple drop-in replacement for worn or incorrectly sized connectors during repairs or upgrades
- Robust form factor designed for frequent assembly and disassembly in service environments
- Compact design helps when space is limited around manifolds, pumps, and valve assemblies
- Works across residential, commercial, and light industrial pipework using BSP standards
Typical Applications:
Adapting pipe runs from 3" to 2" on pumps, tanks, valves, filters, and distribution manifolds; building or modifying water supply and return lines; connecting plant services, compressed air drops, and workshop utilities; irrigation and washdown systems; general maintenance, repairs, and site installations where a strong, threaded reduction is required.
