HW77 breech seal

[slingshot82 32]

Hi, can anyone help me? Im busy rebuilding a HW77 and the breech seal that came in the service kit is nothing like the one currently in the breech. How many types of seal are there for the HW77?

The one thats fitted looks like a fibre washer, and the one in the service kit is a stiff rubbery plastic material but is about 5mm thick

 

Thanks

Hi, mate.

 

I guess your 77's a fairly old one if it has the fibre washer??

 

The newer ones are a nylon/PTFE type and it'll replace the fibre one no problem

 

Cheers.

Aye I would say it will be pretty old, its not mine though so cant say for sure. It doesnt look as though the new one will hold itself in place though. Do you have to glue them in?

 

Thanks

No, mate, it should just push straight in. They're not a very tight fit so don't worry about that.

 

One thing though, make sure all of the old fibre washer's come out 'cos sometimes they de-laminate and leave part of themselves stuck to the cylinder.
