These go great with our silicone tubing for air pumps and valves - great for making adapters or splitters. The three ports have an outer diameter of about 4mm, so 3mm ID silicone tubing will make a nice seal.
Comes in a pack of 5, so you have plenty to mess with.
- Inner diameter: 2mm
- Dimensions of single connector: 28.3mm x 17.4mm x 5.6mm
