This Viton O-ring is black in color, round in shape, has a durometer (hardness) of 7A, and is designed for use in a wide variety of sealing applications.

Viton has excellent heat, fuel, and chemical resistance. Viton is acceptable for temperature applications between - degrees F (- degrees C) to 00 degrees F (20 degrees C). It is compatible for use with non-flammable hydraulic fuels, silicone oil, chlorinated hydrocarbons (trichlorethylene), fuels, aromatic hydrocarbons (benzene) and aliphatic hydrocarbons (propane), as well as high vacuum environments, ozone, and weathering. Viton is vulnerable to low molecular organic acids, ammonia gas, alkalis, amines, glycol-based brake fluids, and super-heated steam.

This Viton O-ring has a shore durometer of 7A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 0, with 0 indicating no indentation.

O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in engines, faucets, flanges, valves and various cylinders. They are circular in shape, with a round cross section and a hole in the center, similar to a doughnut. O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter.

This Viton O-ring meets standards defined by Aerospace Standard AS6A, which is the Aerospace Size Standard for O-rings.

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 lock-up, but Silencer Co website indicates sizes -13 and -18 for Sparrow, and chat room message was confirmed by a SilencerCo representative). I read one reviewer elsewhere that suggested SilencerCo such good company that should just buy from them for 25 times the price-- TOTALLY agree with assessment of Silencerco, and would extend that to include Silencer Shop, but I feel like continuing to buy suppressors from them is more than a fair trade off. Just my humble opinion. The 013 size is supposed to be same as the -13 size listed for the Sparrow smaller o-rings used inside front threads.

I can confirm this is the same o-ring used in the booster assembly for the SilencerCo (SWR) Octane 45 HD. Since the Octane shares the same booster with other suppressors such as the Osprey, you should be good to go on those models too.

Why give your money to Remington when you can a lifetime supply for under $10. These are at least the same quality or better than the ones you will buy from Remington. As stated in the description they are designed for heat and chemicals. So if you have a Remington 1100 shotgun and you want to save some money every year when you change your O-ring then do yourself a favor and get these. Note that you probably don't have to change them every year but hell you just bought a lifetime supply for really cheap so why not keep your shotguns gas ring in tip top shape. You don't want to find yourself in the middle of a field shooting dove and have a major malfunction! I say this because it happens to the best of us...me included! Buy these and change them often!

Purchased these after some of the o rings used for my in-floor cleaning heads became swollen after a few years underwater with the usual pool chemicals and made head removal and reinstallation very difficult. Buying in bulk is better than buying individual. I'm not sure what type of material the OEM uses but it's either EPDM or Viton. I don't believe Viton is better for this application so these are as good or better than OEM in my opinion.

High stakes pai gou can be a harsh mistress. After betting my company's pay roll on a deceptively bad hand I realized I had nothing left to live for and decided to end it all. So I got my trusty 20 Guage Remington 1100, my last true friend, out of the closet in order for her to usher me out of the mortal coil. Wanting to die where I was happiest I took my dear old friend to my favorite clay stand. I was going to end it all after one final clay. With my trapper blissfully in aware I loaded my 2 shells, one for the clay and one to put an end to my pain.
I called pull. The first bird flew from the launcher. I gave it just the right lead, pulled the trigger, then BANG the shot finds its mark and powered the bird in flight. Not too bad for my final clay. I then turned the gun on my self and pulled the trigger; then CLICK, nothing happens. Did my dearest friend abandon me too? It turned out my dear friend was unable to feed her second shell. I hit the latch on the underside and the gun manually feeds.
"Gun malfunction" called my trapper, still blissfully unaware of my ultimate plan. "I'll give you this pair again" was his next statement.
I loaded an other round into the magazine, I figured I could break one more clay before I end it all.
"Pull" I called, again the first bird flew from the launcher and again, BANG, I powder it with ease. Again I turn the gun on my self and again, CLICK, again she failed to feed.
"Might need a new o ring" my trapper remarked.
Of course I could have easily loaded her manually but something about ending my life without fixing my old friend felt wrong. She deserves better. Luckily Amazon had these O rings in stock and they were eligible for Amazon Prime free 2 day shipping. Not wanting to terry too much longer in this sorrow known as life, I was able to order with one click, and with that I was just 2 days away from eternity.
The package arrived earlier than I expected today and the O ring fit faithful ol' Bess like a glove. The package arrived before noon so instead of just one final clay I figured i had time for one final round of clays. I didn't know what I was going to do with the other 9, but getting the 10 off Amazon was still cheaper than ordering one from Remington.
With the new O ring snugly in ol'Bess I headed down to clay range to do one final round of 50 before I step off this mortal coil. With the new O ring in place ol'Bess cycled like a champ almost like she was young Bess again. I think this was my so time highest scoring round, ever. Not a bad way to go out indeed.
Station 11, this was it, final pair. Two more birds before I step into the cold embrace of death. "PULL", BANG, BANG; both clays shatter into powder. I can now die happy. I loaded my final shell.
"Hey there, is that a 20 Guage 1100?, I got one of those for my daughter and she loves it"
My focus was broken as a gentleman approached me with his small talk.
I replied with a pleasantry, and he complimented me on my breaks.
"That's a mighty fine gun you have and that's some mighty fine shooting, why don't you join me and my daughter for one more round?"
I figure why the hell not and accepted.
It turned out my new friend is a super friend at the oil company Texxon Moniker and was looking for some one just like me to hire on and to date his daughter.
This product not only saved my life but also opened the door to my brighter tomorrow.
Thank you no.19 viton Orings I owe you everything.

Well it's just a bunch of quality Viton O-rings but the 5 star thing about it is that Amazon makes it easy for me to get just the O-rings I need, fast and for a decent price. I live in a rural area and getting down to the O-ring district would be a pain and cost more gas money than it costs for me to order 100 of these via Prime.

If you're looking for replacement o-rings for the CRK Umnumzaan knife, these fit perfectly and function much better than the OEM o-rings. I've gone through a few sets of the original factory o-rings (they provided replacements free of charge). However, as those OEM o-rings degraded/melted for the third time in normal use, I finally took the plunge to buy these. They are far more durable and with 50 sets of 2, you'll have enough o-rings to last a long time.

These are so inexpensive I replace one in the Osprey about every 500 rounds to ensure optimal sound suppression. Great price, quality product. Use a little Permatex 80345 White Lithium Grease, 1.5 oz. I also got through Amazon.com, to lube the O-Ring. The 80345 meets OEM specifications for the Osprey.
