Grooved x Threaded Concentric Reducers
A threaded-type grooved concentric reducer connects to grooved pipe with a coupling on the large side and directly to a threaded part on the small side. It steps down from a grooved line to a threaded valve, nipple or sprinkler connection in one piece.
It is used for transitions from grooved mains to small threaded branches, gauge connections and test points. Size combinations and thread standards vary by model, so we confirm your requirement on request.
Main Applications
- Grooved line to threaded branch transitions
- Threaded valve and nipple connections
- Pressure gauge and test points
- Small sprinkler feed arms
Technical Data
| Type | Concentric reducer, grooved × threaded |
|---|---|
| Large end | Grooved; joined with a coupling |
| Small end | Female thread (thread standard by model) |
| Size combination | By model (please ask) |
| Body | Ductile iron GGG 40.3 (manufacturer data) |
| Sealing | Coupling gasket on grooved end; thread seal on threaded end |
| Finish | Painted (by model) |
| Working pressure | By model and connection |
Material Options
| Part | Threaded reducer |
|---|---|
| Body | Ductile iron GGG 40.3 |
| Large end | Grooved |
| Small end | Female thread |
| Finish | Painted (by model) |
Which material? Use suitable thread tape or liquid sealant on the threaded end; the thread standard (BSPT/NPT) must match the part being connected.
Advantages
One-Piece Transition
