How long should an HW break barrel breech seal last

[Barryg]

Not a springer expert but literally every couple of years doesn't sound right

That's what I thought, the seals look OK until you start to remove them.

10 years min to crumble, probably more. They don't even harden for like 5 years. maybe it was left in the sun ?

That's two I have had now and not left in the sun

Looks like the one I took out of my 97, like old cheese it was.

Replaced it with a Br1t Seal, did the piston seal too & saw a 2 ft/lb improvement. I wouldn't bother replacing seals with standard ones, after market ones are better.

Why is the common abbreviation for British not allowed ?

Just lay a sheet of bog paper over the breech. If it moves attend to the reason.

I once had a piece blown to bits....

You need Izal.

Well, in my experience the genuine HW ones last a very long time......

One of my 95s.....bought new in 1995. Fitted V-Mach kit in 2014. It was still shooting brilliantly, and very consistently two years ago. So, breech seal about 27 years old!

Conversely, in 2019, a "supposedly genuine HW" one in a 35 lasted two months!

P.S...the 95.....although the seal looked flattened and to be well past its best, it was still quite pliable and, as said, still performed very well.

What lubricant do you use?
Could it be deteriorated by lubricant?

I did wonder that, but the breech only gets an occasional wipe with Parker-Hale Express Gun Oil.

Tony, 27 years that's amazing The broken seals in the pic did look OK and worked I only decided to change them because the fps was inconsistent, I wonder if you tried to remove your old ones they would crumble, I have now fitted a new standard seal and the fps are consistent, but I'm thinking of getting a heavy-duty seal from somewhere if they are easy to get, I have had almost indestructible Diana breech seals from Terry Robb but not HW.

I would well imagine that some lubes wouldn't be a seal's best friend, Neil.
