Yes, they had a little bit of foam around the edge too when new. For the pins I use a finish nail cut to the right length to slide in and hold the flaps. The cover holds the pins in.

NOS Non-Return Air Flaps. Dealer purchased in the 80s, on the shelf since.
L Air Flap 021 119 263 A
R Air Flap 021 119 264 A
Flap Pins 021 119 270
VW Parts Book adds: "Shorten to 56mm for left flap".

They had small foam seals glued onto them. Over the 30 or so years on the shelf, they have dissolved and disintegrated so all that's left is the glue. See Photos. The Foam kept them from rattling more than for sealing.

I'm installing a pair of these non-return flaps and am going to glue a small foam and wondering what temperature range these pieces should expect?

Thanks!

[BUSBOSS]

Any suggestions on source for suitable foam? What are people using? Thanks in advance!

As Tcash said, they're really for anti-rattle. Cork, rubber, etc will work, but foam ain't gonna last.

Greetings,
I am working to determined what happened too overheat my type 4 and it appears that these flaps may be a root cause.

IF these air non-return flaps get stuck closed, it results in cooling air being blocked from the heat exchanger and thus overheating exhaust manifold.

Thoughts?

[busdaddy]

It's possible, but it would have to seal up real good, how did it get stuck?

But a cooked heat exchanger isn't going to do much of anything towards making the engine hot, it's downstream of all the cooling air.

They will certain break off and cut down on the air flow through the heaters lessening the heat to the cab.

the flaps prevent the overhead fan from pushing air backwards. When I assemble an engine, I use a small video camera ($16, link below) and a hair dryer to verify that both flaps are operational. They can bind.

All of the VW Type 4 style engines that I worked on for myself and a few acquaintances, were missing all of the flaps & covers, as well as the left-hand exhaust heat-exchanger & silencer (i.e. muffler in USA parlance!) support bracket, which reputedly fastens onto the engine cooling-fan shroud.

I managed to acquire a set of flaps & covers, but I have yet to see an exhaust support bracket in the "flesh". If I had a paper pattern, I could make one of these brackets out of stainless-steel.

This is 1975-1978. There are different ones for different heat exchanger configurations 021 256 303 B is the 1975-78 part number. It may also work on the earlier heat exchangers, I don't know. You can google the part number. I think Scott may have made some reproductions at one time. Ken Madsen at TheBusco may have a used one.

In Great Britain, the 1972~78 VW 17/18/2000 Type 2 exhaust heat-exchangers & silencers are all the same.

In Great Britain, the 1979 VW 2000 Type 2 exhaust heat-exchangers, which have the same exhaust-port connections as the 1980~83 VW 2000 Transporter T3 (i.e. Vanagon in USA parlance!), looks very similar.
