The 13mm Standard and double Barbed Fittings will fit perfectly onto any 13mm internal diameter pipework. Barbed solid plastic connections ensure a strong and secure grip on your pipework. No tools are required as they just push into your 13mm pipework and connect to your 4mm pipework, these are typically used in in drip systems, homemade hydroponic irrigation systems and can also be used outside to water hanging baskets, pots and raised beds.
We recommend to use White Reinforced Flexible PVC pipe with these fittings, other pipes might a little bit tight so you will need first to put the pipe in hot water to make it a little bit loose and after you can put the fitting in.
