Self-Healing Injection Ports (20mm / 10 Pack)

£2.00

10 x 20mm diameter butyl rubber injection ports.

  • 0-1 working day dispatch. Order and pay before 1pm Monday to Thursday.

We recommend drilling a 10mm hole in your lids which will provide a tight seal after squeezing the rubber injection ports into.

Please note: these aren't the same injection ports that are in our grow kit lids - these are bigger, sturdier and perfect for jar lids.
