I cut the thumb off a pair of heavy duty rubber gloves. Its relatively easy to "feel" if its full of water or dust, and easy to slip off and replace.

Hi Dinosaur,
I like that idea!

It sounds as if maybe you used it to replace the standard duckbill dump-valve - is that right?
Or did you place it over that valve, on the outside?
And: do you secure it in place with a small cable tie, bulldog clip, or what?

Cheers, Andrew Milne

I am led to believe that these little dust "dump valves" are a donaldson invention, perhaps Donaldson themselves can supply something? We use a similar looking things on the trucks at work, but they have about a 3" inlet on them.

google Vacuator Valve

Donaldson make replacement valves in numerous different sizes
On my old tdi defender I had to make an aluminium sleeve to expand the sealing surface to take a new donaldson valve but it worked well.

they are pretty cheap from a truck filter/ fuel injector place

s

I've got some measuring to do...

Yep, replaced the duckbill.
Just cut thumb off, and stretched it over the bottom. Its a tight fit but it stays. For the price of a rubber glove, I replace it about 3 times a year. Have had no dramas so far.
