how to seal power steering lines

[halfcab1969]

I purchased a Borgeson steering box and the correct adaptors to use braided nylon high pressure AN style hoses. My Question is what product do I use to seal the threads on the adaptor to pump and adaptor to box connections. Tape or thread sealer.

I just screwed em right in.

NOTHING!

Sealing tape or paste only works on tapered pipe thread. Those fittings are compression or O-ring. The only thing tape or paste will do is contaminate the closed system.

Tighten, loosen. Repeat twice. Should seal

There is wisdom in his post…

With new inverted flare fittings and seats, it is often necessary to “set” the connection by crushing the flare. That might require “over-torquing” initially…then relaxing the connection and re-tightening to the correct spec.

Drives me crazy when lines are either under-crimped, (and loosen and leak.) or when over-tightened and left that way. (And then rounded off when serviced later)

Do what nickgp says. tighten, loosen, and then tighten correctly. This is not necessary for tapered thread, or o-ring, or compression. Just new flared connections.

Thanks James, again, I really appreciate all the knowledge on here.
