I use a drip watering system for my tomatoes etc when I go on holiday
and I use some Gardena fittings. After just 2 years of occasional use
I find the tiny thin 'O' rings are perished. One is on the expensive
pressure reducer. These are smaller than the standard 9mm rings on
water fittings. I cannot find these anywhere so I mailed gardena.
They have finally replied saying they do not supply these as spares but
if I wish I can buy a new fitting complete cheaper via their internet
system. Has anyone found this? I shall not be reccomending Gardena
Keep in mind that O rings change diameter and thickness as they wear out.
I would suggest bringing your parts and o-ring to your local plumbing
supplier. O-rings come in standard sizes, and are common.
