Are they worth 6GBP?

I bought a similar set from RS a few years ago for around £20, and they've come in very handy.

Have you ever considered getting help for your Aldi obsession?

[Lobster]

Well why wouldn't they be, coming from Aldi? ;-)

55p I paid for two 1/2" o rings in a washing machine shop.

The message from "The3rd Earl Of Derby" contains these words:

I've got a couple of smaller kits that cost me a quid each. There's not as many of each size, though I may have more sizes. Very handy to have for those odd occasions when only a new O-ring will do.

[HLAH]

Cheaper bigger set here

Probably same spec.

Actually it'll be 10.88GBP altogether with p&p :-)

[HLAH]

True, though I can always find stuff to buy to get it over the free delivery threshold at Toolstation :-)

Following on from the post about a moderated forum, instead I was going to suggest a new gorup uk.d-i-y.aldi.

[Ed Sirett]

the larger sizes, this has let me down a couple of times.

The use of the O-ring as shown in the picture was silly as this application should use a flat washer.

[EricP]

BUT, unless you have a fetish for eating them, won't buying the odd one every other year at the corner shop do?

[John Rumm]

Well if you buy O rings from a greengrocer, what do you expect?

[Dave]

It's not so often you are wrong, but you are right again :-)

Another aspect of these low cost O rings, is the question of if it is fit for purpose? Under normal domestic use, an O ring from the op source may not be up to its final use.

Ed, how do the various materials used to make O rings, behave when in contact with gas? What are they made from? How do they react?

Can these O rings be used for hot water? Can they be used for cold water (less that 0 degrees C)? Are they frost safe? Can they be used on a petrol machine?

I ask this, because the material that they are made from may not suit every application. Also, depending on what material they are made from, determines what lubricant is suitable for them. e.g. Silicon rubber requires silicon lube.

Exactly. NASA got themselves into difficulties because of this. I'm not suggesting that Morton Thiokol shops at Walmart for O rings, but it's clear that the right ones are needed for the application

[The3rd Earl Of Derby]

There's some that are very small...I think you'll find one suitable to keep your pecker up. :-)
