Vacuum line connection seal

[Don W.]

Are there any recommended glues or sealers to help seal and hold the vacuum line connections?

Rubber cement.

If you're talking about rubber vacuum hoses connected to nipples, they should hold without any type of glue or sealer. If not, the hose is deteriorated or the wrong size.

Swabbing the inside of the hose with a Q-tip wetted with silicone spray lube should keep the hose from seizing to the nipple.

Don, if your talking about the fittings that thread into the carb. or intake manifold, I use a little teflon tape, or pipe thread sealant.

Threaded vacuum connections usually consist of a flare fitting and B-nut. The seal is at the flare not the nut. If the connection is a pipe thread, then Teflon tape will help.

The OP needs to describe the exact nature of the connection he's talking about.

Hi Don,
I used the original hoses on my 71's restoration.
I followed a suggestion I first heard from member Chuck Gongloff to cut 1/4" to 3/8" off each end of the hose (if there's enough length) which allows a seal in a fresh area of the hose.
Terry's use of rubber cement sounds good too.
