3" V Band Gasket

[a4kquattro]

the best types of v-bands have provisions for sealing built-in. For example, the v-bands I sell have a grove machined into them and come with a thick copper sealing ring to deal with the "cold blow out" issue:

we use these on aircraft bleed air,and air con systems,to stop the cold blowing issues,the clamps are designed to be tightened ( 75-95 inch pounds i think ) then hit with plastic mallet all round,then re-tightened,hit again and tightened once more,then wire locked together,after that we dont really have an issue with blowing,hope this helps.
Ps if you still need one,i can have a scrounge round the hangar and see if any laying around........

Yeh most of the ones on aircraft dont have gaskets. They tend to have a "lip" on the mating services, like a spring so that when the v band is tightened, the two lips are sprung against each other to create a seal. There seems to be a number of aircraft fitted with vband with e or w shaped sealing rings now thoght, but the gaskets are one use. See if I can get some pics next time I come accross one.
