Composite Push-In Fittings
NPTF/Inch Series 7000
Series 7000 push-in composite fittings
are compact and lightweight. They offer
easy maintenance of the collet and
internal o-ring seal. All materials can be
easily recycled.
The nickel-plated brass collet
maintains the same technical
characteristics as the other
nickel-plated brass fittings.
It provides a uniform grip
around the entire surface
of the plastic tube. This
ensures high reliability and
long service life, especially
after several connections and
disconnections of the tubing.
Series 7000 composite fittings
are especially suited to
lightweight applications and
compact assembly locations,
typical in the automation
markets.
