11-87 o ring question

Postby Splatt » Tue Mar 04, 2014 9:25 pm

How critical is the size of the o ring?
We have some at work, but they apear to be slightly smaller in diameter and just a touch thicker than my well used one on the gun.
Is mine just old and wore or I need to replace it with one exactly like it?

You do not really need it. I have shot my 11-87 for about 10 years without it.

The o-ring is a viton 021. They are less than a dollar at any full line hardware. Why go without it or use the wrong thing? Better to leave the old one on until you save up a dollar. :help:

Do you order those O rings that you use? Where from?

I get them directly from Brownells but the local ace hardware carries them too. I am not sure how someone's 11-87 works without the O-ring. I have had several and repair them for customers all the time and have not found one that will cycle reliably (or at all in some cases) without the O-ring installed. They even have issues with a broken or worn out O-ring with light loads. :huh:

If the recoil spring is weak and you fire only heavy loads the 11-87 or 1100 will function especially when the mag tube is very dirty. In other words a poorly maintained gun MAY work without the o-ring. :lol3:
FWIW my SX-1 doesn't need one to function with heavy dove loads, but that's a different animal.

However, I don't understand why anyone would shoot his firearm intentionally with a critical $1 .00 part missing.

Chris, you can get 3 viton 021 o-rings mailed to your door for $3.21 from eBay. I ordered some yesterday. They last nearly forever if you are not ham fisted. I just bought an old 1100 3" mag last week with a nicked cheap o-ring on it.

Thanks for the tip on ebay. I should have known to check that source out myself. I will order some of those for both the 12 and 20.

Both my 20 and 12 Escorts (11/87 copy) will not cycle magnum loads without the o rings. My 1100 12ga will not cycle either without the ring installed. But, I try my best to keep my guns clean. I intend to keep my o rings in good shape as well. The o ring being so inexpensive of a part, its silly to over look it.
