ERdept Posted May 19, 2009 Share Posted May 19, 2009 Just curious about the O-rings on this thing, for curiosity's sake. Are the O-rings on the gas pistons composed of rubber or silicone? Quote Link to comment Share on other sites More sharing options...
jantonio54 Posted May 20, 2009 Share Posted May 20, 2009 I'm curious why you'd care. If they needed replacing, wouldn't you order them OEM from Benelli? Quote Link to comment Share on other sites More sharing options...
GENELEO Posted May 20, 2009 Share Posted May 20, 2009 Silicone(?), rubber won't hold up to the heat from the gas, or the gun oils and lube. Quote Link to comment Share on other sites More sharing options...

I had a Remy 1187 and i think it had rubber ones, but Brownells sold a silicone replacement. When you think about it, a car has a lot of rubber in the engine keeping heated parts working together.

I just bought a repair kit for an 11-87 just a couple days ago, Remington calls the material "Viton", what ever that means. All the "older" cars used rubber components, but most modern "rubber" components are either silicone or a high silicone content mix, as real, or natural rubber detereorates rapidly. Look at natural latex gloves. The ones we carry on our gunbelts have to be replaced every few months, but the nitrile gloves hold up for a long time.

jantonio54 Posted May 20, 2009 Share Posted May 20, 2009 (edited) Uhhhhh, I think I stated why I was asking. then I guess that makes our reasons identical for asking a question. As I said, I'm "curious" why you'd be curious. I don't mean to be a jerk, or argumentative. I just wondered why it would make any difference.

Unobtanium Posted May 20, 2009 Share Posted May 20, 2009 That is like asking "Is that paint on your car enamel, or clear-coat?" Either answer you get won't tell you jack. There are so many ways to formulate paint--just as there are synthetic components like rubber or silicone. Look at tires. My tires, you can floor my Trans Am in the rain and they dead-hook. Cheaper tires, they look and feel the same, but spin all over the place. So much formulation goes into this kind of stuff. All that being said, Viton O-rings *SHOULD* be an acceptable replacement, but a $4.50 part for a $1600 shotgun is nothing. Yes its stupid that it costs that, but really, how many do you expect to have to buy? Duggan has been through 12,000 rounds and only messed up one O-ring due to his heavy-handed cleaning methods.

Amen to the "heavy handed cleaning". In the past month, I have replaced the barrel seal on three different Remington 1100's, and none of them were "worn out" all were either nicked, or torn when the owner carelessly cleaned the gun. On the oldest 1100, the piston and piston seal were actually eroded, and the barrel seal would have been useable, if the owner had been more careful in dissassembling the shotgun.

trackbird Posted May 20, 2009 Share Posted May 20, 2009 I just bought a repair kit for an 11-87 just a couple days ago, Remington calls the material "Viton", what ever that means. Viton is commonly used for valve stem seals inside of automotive internal combustion engines. It's typically pretty durable stuff in the right application.

edwordsigh Posted November 25, 2009 Share Posted November 25, 2009 Sorry to be digging this thread out of its grave, but I would really love to know which size viton o-ring is.. I happen to accidently rip the thing while I was cleaning and will be in need of a replacement. Brownells is sold out and doesn't offer information on what size this is.

Take the corpse to the store and compare. Quote Link to comment Share on other sites More sharing options...
