Overview
The TSP 1-1/4″ black malleable iron reducing tee is a standard threaded pipe fitting engineered for industrial and commercial plumbing applications. Constructed from malleable cast iron with a black finish, this reducing tee accommodates pipe size transitions within a single component. TSP malleable iron pipe fittings conform to BS EN 10242 and are designed for pipe systems carrying liquids, gases, or steam under pressure.
Key Features
- 1-1/4″ main line connection with reducing branch connections
- Malleable cast iron construction ensures durability and impact resistance
- Black oxide finish for corrosion protection in industrial settings
- Female NPT (National Pipe Thread) connections for easy installation
- Rated for 150# (300 PSI) low-pressure applications
- Suitable for use with Schedule 40 steel pipe and EN10255 tube

Replaces / Drop-In Replacement For
Verify compatibility with your specific system configuration. TSP 1-1/4″ reducing tee fittings are direct replacements for equivalent 150# malleable iron reducing tees in standard NPT thread patterns. Confirm exact branch size configuration (1″ x 1″, 1″ x 3/4″, etc.) before ordering.
Works With
- NPT (National Pipe Thread) standard fittings and connectors
- Male NPT adapters and union connectors
- Malleable iron elbows, unions, and couplings
- Black steel and carbon steel piping systems
- Pressure gauges and relief valves rated 150# or higher
- Pipe sealing compounds and thread tape (PTFE) for NPT applications
