Brocock Contour leaking filling fitting.

[bhodge]

...I'm waiting on a reply from Brocock to buy a new valve.....

Good luck with that one matey, Brocock are not the most helpful people when it comes to asking for technical assistance. Sounds like you're nearly there anyway.

There are two seals on the centre shaft, one large, one small.

The small one is definitely donut shaped and I suspect the larger one was once upon a time!

If both seals are donut shaped and I can simply measure them and buy new ones 'off the shelf' in those sizes, would they be of a certain rubber type?

The small o ring seems to be OK, the larger one is dead.

The large one is 2mm ID, 5.5mm OD, 2mm thick, black in colour and quite hard.

Edit,

Just had a hunt on rubbishbay and found a 2mm C/S x 2mm ID in Nitrile 70 Shore, £1.80 delivered in the UK.
I bought it and I'm guessing it will be OK. If not, it will just leak again I suppose?

Edit,

I just bought a BF fitting as well under their recommendation as a back up.

The rubbishbay o ring seems to be holding for now, but Brocock have stepped up big time and offered my daughter a new valve

So I'll keep the o ring in so she can use her gun until the new unit turns up.

New Brocock seals fitted and working as intended, thank you Brocock
BF 1/8 BSP came and does fit the recess, but keeping that as a spare for one day

Also had a fiddle with the trigger and got it totally perfect, almost as good as my Steyr LP10 pistol
To get it this good the spring coils had to be heated with a pencil torch and flattened then trimmed off. Just kept doing a little at a time until the springs were just right. It's an absolute joy to shoot now and brings a smile every time the trigger is pulled

I'm glad you had a good result with the valve, and your trigger-work sounds most impressive.
