Where to get larger O rings

[Curious_character]

I have occasional need for O rings about the size of a flashlight body or lens, say 25 -30 mm or a bit more either side, of various thicknesses. There are a lot of O ring assortments out there, but they seem to have few or none in this size range. Can anyone recommend a source for an assortment in this size range?

How about this or this?

The aldi o rings looked interesting... But the bigger sizes are like 3+ mm thick, which is a bit of an overkill, especially for the lense one.

Dealextreme.com have lots of different size o-rings. Might want to give them a go.

In the dealextreme.com site, goto Flashlights/Lamps category, DIY Parts and Tools. Alternatively, do a search for 'o-rings' and you will get around 14 selections ranging from 16mm to 30mm.

Fluid power supply houses, hydraulics, pneumatics, etc.

The largest size in the first kit is 25 mm. Guess I wasn't clear -- I'm looking for an assortment with diameters in the general range of 25 - 30 mm, or a little wider. And the second kit is like quite a few others I saw when searching -- the description has no information at all about what diameters are included.

Thanks, guess I could build my own assortment. But I was hoping for a kit already put together, like the smaller size ones I already have.

Get yourself a Parker O-Ring handbook.

McMaster-Carr has a fairly decent explanation of o-rings on their site. That's where I get mine even though you can get them cheaper elsewhere.

MSC also carries an extensive line of O-rings.

Here's a link to their website:
