I use these on both MSR and Brunton camping fuel bottles. In addition to camping, I use the bottles to store motor oil - they tend to be much more leak resistant than plastic quart bottles. The size 213 o-ring fits nicely, 15/16" inside diameter, 1/8" thickness. The viton material is supposed to last longer than stock O-rings (nitrile?),

OK, they won't allow me to review 018 and 013 separately, even though separate items. So here is combined review. Great way to get bulk replacement O-rings for Octane/Osprey/Sparrow suppressors. I read in chat room that 018 is also same as the larger O-rings used on the SS Sparrow (can't confirm personally because Sparrow still in

I ordered a 013-75 viton o-ring. I received an o-ring that has a cross section much too thick for a 013 oring. The label on the package (as well as the item description) says it should have a cross section of 0.070" or 1.78mm. This is obviously much bigger, measuring 2.68mm on a caliper with the material slightly depressed (so probably

My home AC was leaking from the schrader valve. I was unable to replace it with C&D's schrader tool; however, I found out the cap can serve the same purpose in preventing leaks! I bought this set and have now replaced my plastic AC tap caps with these brass ones, and have no leaks in over 2

We often see cars with missing fuel pressure test port caps, these caps fit most standard ports, but not the smaller ford style. Keeping the port covered protects against fire in the case of a leaking valve and keeps dirt out of the

These o-rings are a great deal. I purchased them to repair brass hose nozzles when they stop working, and they work great. Not only can I repair many hose nozzles, but the 2 kits also come with every size imaginable, SAE and metric, for repairs of any future projects that might require a new o-ring. I would give this 6 stars if I could!

This kit has a great assortment of O-rings of different Dash. I need one for a leaking faucet in my kitchen, but soon found out the old o-ring I was replacing was thiner than the one I got out of this set.

Good kit, lots of different sizes.

I bought two different kits to cover the range of different thicknesses and diameters.

I repaired a nail gun that required a $110 seal with a $0.10 o-ring of the exact size to fill the space. The $109.90 I saved paid for both kits and left me with about $50 in hand, plus of course

This works great to repair the anti-vacuum valve on the steam boiler of a Profitec 700. I suspect that it will work fine for other machines too. Its cross section is a *tad* larger than the original o-ring, but it will still seat fine and hold pressure. These should probably be replaced every few years because they are subjected to

I am using these for a rebuild on a Mercury Grand Marquis EATC (Electronic Temperature Control). Recently my heat and AC would come out only through the defrost. They worked properly by the heat/AC was not diverting to the floor or vents. Apparently this is common with Ford/Mercury EATC's that are vacuum controlled.

I had some trouble figuring out if this was the right part for my hot tub, although I later realized the old ones did actually have the model number, and I just missed it. Anyway these seem to be fairly standard, so if they look right, they probably are the right ones.

I bought a set of both English and Metric rings by this company. The quality is just OK. There seem to be minor imperfections from the injection molding process (I assume). Nice cases. I thought these sets would satisfy most of my o-ring needs, but I was mistaken. I failed at finding the first 2 sizes of o-rings I needed from these kits.

You should probably ask yourself, "do I actually need a 740 piece set of rubber O-Rings in an assortment of sizes?" because realistically I needed like, four o-rings in one size tops.

The package has a large assortment of o-rings but they were all mixed up when they arrived. The o-ring holder does not have any way to keep the rings in place at the top so if the box is tipped the small rings get mixed in with all the others.

There are a lot of naysayers on this item and it's my belief that some those people who order these o-rings don't know what model number of Jandy Valve that they have and order these O-rings only to find out that these O-rings fit a different model number and consequently leave negative feedback on this item.

I highly recommended you replace your o-rings if you have Jandy valves in your pool pluming. We had air bubbles in our pool lines and thought we had a leak somewhere.

Mercury Outboards have a flaw in their 2-cycle oil pump design, basically there are two types of these pumps, those that are leaking, and those about to leak. They say the pump is not serviceable, and if you don't catch it while under warranty, the dealer is happy to sell you a new pump at $700 or more + labor. Not only is the pump

Not finding the exact replacement O-Rings for the Harbor Freight Hose Reel, this 2.5mm (thick) by 11mm (ID), totaling 16mm was the closest to meeting the OEM specification of 2.4mm (thick) by 11.2mm (ID). The difference between these is, the Viton ring has a .2mm smaller ID, but the actual ring thickness makes up for that. In the end,

Very poor quality. Excess flashing on both inside and outside on all o-rings on what looks like a glue line(?), not to mention they are undersized in all dimensions.
