It’s a pain in the arse when water starts leaking around the connector on a garden hose. Usually the o’ring has disintegrated, or the hose connection has started coming adrift.
The physical hose connection is often quite easy… You can tighten it up.
But if the o-ring has broken, or become perished. You will need to get a new one.
But, what size is the o-ring..?
The standard 1/2″ garden hose connectors and fittings have the following o-ring size:
|O-Rings – Garden Hose Fittings|
|Hose Size||Unit||Outside Dia
To measure an o-ring, you will need the following dimensions:
Outside Diameter (OD) & the Internal Diameter (ID)
These two measurements (OD & ID) will give you the thickness of the o-ring, (or, you can just measure it)…
Cross Section (CS) Thickness = (OD – ID) / 2
You can use a ruler to measure an o-ring, but if you have a digital caliper, it’s so easy…
The cheapest method of buying o-rings is often quoting the size and quantity you need, rather than buying a small pre-packaged quantity from a branded garden hose manufacturer…
Don’t forget to ask for EPDM rubber o-rings as they will last a lot longer in sunlight.
If you’re not sure what you need, sometimes it’s a good idea to have a look? The list below may give you an idea of what’s available, what to look for, and how much the part might cost…
