Description
A GI union joins two threaded pipes with a joint that you can open later. It has three parts: two ends and a centre nut. Therefore, you can remove a pump, meter or valve without turning or cutting the pipe. We stock galvanised unions at our showroom in Nad Al Hamar, Dubai, for same-day collection across the UAE.
First, choose the size to match your pipe. Next, choose the seat: a flat seat with a gasket, or a taper seat with an iron-to-brass or iron-to-iron face. Also, place a union next to every pump, meter and water heater, so service is easy. In addition, we stock matching GI nipples and elbows for the same job.
Why Choose Our GI Union
- Easy service: Open the nut to remove equipment in minutes.
- Rust resistant: Hot-dip galvanising protects against water and humidity.
- Strong joint: Malleable iron takes pipe stress and vibration well.
- Matches our range: In addition, it fits our GI nipples, elbows and tees.
