Best place to purchase a box of all the types of O-rings?

[soarwitheagles]

I was looking at some videos of replacing all the o-rings on my .25 Hatsan Flashpup.  I am almost certain I blew out the breech o-ring located inside the barrel.

I would also like to replace the o-rings on my Marauder.

It would be so nice to purchase a couple of kits that would service a variety of air rifles like some of the air rifle shops use...

Anyone know where I might purchase a box of o-rings with all the sizes for these air rifles?

Thanks,

Soar

The best place I have found for "O" rings is this place,

You just have to know the sizes etc.

Thanks for the info!

I forgot to ask:

What's best material to use with an o-ring:  buna, silicone, etc.?

Harbor Freight has a metric and SAE assortment boxes of o-ring for I think $7.99 each.

Check if McMasters-CARR has the o-ring you need.

Hi, Generally the standard O-Rings Are buna.  I have changed to Urethane just on the Breech O-Rings.  If someone forgets to close the Bolt the O-Rings tend to stay in the barrel, instead of blowing out. 

The O-Ring Store used to be one of my customers.  They source from Quality sources.  Their name is on the end product.  Harbor Freight not so much.  If you source from Asia you end up with water in the O-Rings as the relative humidity is higher and makes it way into the O-Ring.

My 2 cents your mileage may vary!!!

The issue with the HF o rings s that the standard and metric are not real. The Metric set is standard and the measurement is given in mm. However, they are not standard  metric sizes. Only standard that have been measured in mm.  I have both sets here and they are identical in every respect other than the color of the box they come in. Not common mm at all.

Michael's definitely right, I have both and like he said they virtually identical to each other.  I order all my o rings from the O Ring Store, I've got some coming right now as a matter of fact.
