Check valve...

Ive been digging around for an hour or so on the net, trying to find a 3/8" check valve. I know the minivans had the one for the brake booster, but i havnt had much luck finding one. Does anyone know of a suitable replacement?

There is a plubming valve called a Brady valve that is available in plumbing departments like at Lowes or Home Depot. A couple people have used these as check valves in a BOV/BPV circuit. Don't know if it would work for your application or not. They do come in different diameters but I'm not sure if they have 3/8"

See this thread from 2002. The links don't work.

Forcedbird tried one, don't know if he is still using one or not

The help! section of auto stores usually have generic check valves of varying sizes also.

I checked out the help section, and all they had was one for vacume hose, and a few for brake boosters.

I found a few plastic ones on the net, but id much prefer a metal one, there isnt going to be much pressure, since its for my PCV system im planning on trying out, but i still dont want to chance it.

next time you're in the junkyard...go to any honda car and look by the brake booster, inline there will be a 3/8 check valve. I picked one up the other day, looks like a very effective setup.

Picked this up at the 'yard off a late '80's/early 90's Nissan. On the firewall to the left of the brake booster. Easy to see and access.
