Push-in plastic end caps for round steel pipe. They cover the sharp open end, help keep water, dirt and critters out, and give the job a finished look. Also known as pipe caps, pipe end plugs, tube inserts or round post caps.
Sizes: 20NB, 25NB, 32NB, 40NB and 50NB.
Sizing: Caps are sized by nominal bore (NB), not outside diameter. For example, 25NB pipe is 33.7mm OD, not 25mm. Use this as a guide:
| NB | Inch | Pipe OD (mm) |
|---|---|---|
| 20NB | 3/4" | 26.9 |
| 25NB | 1" | 33.7 |
| 32NB | 1-1/4" | 42.4 |
| 40NB | 1-1/2" | 48.3 |
| 50NB | 2" | 60.3 |
Features:
- Push in by hand or with a rubber mallet — no tools or fixings
- Sized to suit NB steel pipe, 20NB to 50NB
- Plastic construction won't rust
