NOT:NEach end connection/fitting uses two o-rings. The
o-rings will sit on the lip above the point where the
threads start.

2. Lubricate the o-rings with DTE-24 oil or equivalent.
3. By hand or with a wrench, screw one tting ush onto the
end of the body to secure the cone.
NOT:NIf at any time during the installation the fitting needs to
be unscrewed (even partially), unscrew the end cap all
the way and make sure that the o-ring is seated properly
on the end cap before putting the end cap back on.

o-ring if there are any nicks, cuts or scrapes) and reinstall
making sure that it is seated properly.
