O-rings and everything else

Feinman was deeply involved in the science of space and nuclear physics, and there has never in my experience been such a wonderful self-criticizing and hilarious autobiographer!

I purchased a nickle-plated O-ring which opens with screws from the Buckleguy website. Very fast service, great prices and best of all I was able to repair a strap on my favorite purse when the screws fell out of  the original O-ring and I lost part of the piece. I had 1 of 4 straps that was not attached and everything I tried looked tacky. Fortunately a friend of mine told me about the site and all of the products. I found the website helpful because they have a number of finish and size choices and the diagrams and measurements make it impossible to not order the correct size. I highly recommend this seller and my only complaint was that I could not use their review section because it was run by another company that would not post this review.  http://www.buckleguy.com/gate-o-rings/

Just received the CL200 and it looks good but it DOES NOT INCLUDE an O-RING.  It should say O-RING not included, because now I can't hook up and use until I get it.  Include $15 cost of o-ring in this purchased, just wish I knew this before ordering.

Comes in handy - never know what random o-ring you are going to need.  Probably have a near life time supply of them with this kit.

Works perfectly, and made short work of my deck.  The only problem I had was that the o-ring sits inside a plastic piece.  I managed to skip off a screw once, and chip that plastic piece.  Now the o-ring doesn't like to stay in place.  I had to glue (ever tried to glue rubber before?) the oring to keep it lock in.  Once I did that, it kept working fine.  I simply should have been a little more careful about how hard I was pushing.

This o-ring gasket kit does not include all of the o-rings needed for the marineland C-360. This kit only includes 2 small o-rings for the valve block that requires 4. The 2 that come with the kit are slightly larger making it impossible for me to fully insert or lock the valve block back into place. I had to put my old ones back on. The large canister lid o-ring did fit but made the lid quite snug to get back on. I bought this kit because my pump was sucking air and the lid o-ring seemed to solve this so I will bite the bullet on the $12 and not return it. I would not recommend this product since the smaller o-rings are not correct.

I have had the AR383 for over 3 years and have several broken or missing O-rings.  I found O-rings at my local home center that fit perfectly. The AR383 is working now as it did when it was brand new, and I have no leaks anywhere.

The replacement O-rings I found are about 50 cents each. Standard fractional inch sizes found at home centers work perfectly.  Here is the information I have gathered.  Hope it helps others easily find replacement O-rings without measuring and without multiple trips to the local store to get the correct sizes:

Manufacturer's O-ring replacement kit (Qty) Size
Large end of pressure hose (1) 10 mm x 2.5mm-N90
Bayonet/Soap Bottle (3)  8.0mm x 2.0mm-N70
Pressure Hose to spray gun (1)  5.2mm x 1.5mm-N70

MM  (Millimeters)  I.D. (Cross Section)
Large end of pressure hose  10  (2.5)
Bayonet/Soap Bottle  8.0 (2.0)
Pressure Hose to spray gun 5.2  (1.5)

Decimal Inches  I.D. (Cross Section)
Large end of pressure hose  .394  (.098)
Bayonet/Soap Bottle  .315 (.078)
Pressure Hose to spray gun .204 (.059)

Fractional Inches  I.D. (Cross Section)
Large end of pressure hose  3/8 (3/32)
Bayonet/Soap Bottle  5/16 (5/64)
Pressure Hose to spray gun 1/4 (1/16)

Local Hardware/Home Center Thrifco Plumbing Brand  Cost  Note
Large end of pressure hose  550T  I.D 3/8  O.D. 9/16 Wall 3/32 $0.99 for 2 Works perfectly, no leaking
Bayonet/Soap Bottle  544T  I.D 5/16  O.D. 7/16 Wall 1/16 $0.99 for 2 Works perfectly, no leaking
Pressure Hose to spray gun 546T  I.D 1/4  O.D. 3/8 Wall 1/16 $0.99 for 2 Works perfectly, no leaking

The O-ring used for the large end of pressure hose appears to be the same size as the supply hose quick coupling O-ring.

Keep O-rings lubricated with Moen grease for protection and ease of assembly.

Using vice grip pliers lock them onto bit and pull the bit out. The o ring keeps it firmly in place which keeps you from loosing the bit. I have ordered the set to have multiple bits. Just use common horse sense and the bit is removable.

Disappointed that Two Blue rubber O_Rings supplied for the outer housing groove, but, missing an black (smaller) O-Ring for the inner groove.

Great filter at a good price.  Should include O ring.

This lid O-Ring is loose compared to the old o-ring I was trying to replace? I would like to know why, but it is not worth my time and money to spend trying to resolve this silly problem!!

Excellent product, excellent price. Brand name O-rings are way overpriced

The O-rings were fine and it took a bit to fit them on properly and figure out a technique to do it quickly. They didn't seem to make much of any difference in terms of sound. Button pressing you can notice a slight difference. Not sure if it's worth the money. /shrug

I was amazed by the various sizes of these o rings. I can use them for my microdermabrasion set to my vape pens. Worth every penny.

Great product; very sturdy. I didn't see the extra o-ring in the packaging but those are pretty cheap.

My 02 CRV has three o rings on each injector. This kit includes the proper two large o rings but the incorrect small o ring.
