FleetFit - Vehicle Push-In Fittings

(Inch and Metric Tubing)

● Simple tube connection and disconnection - no
tools required

● Fewer component parts - Internally machined
form in body to secure collet reduces number of
potential leak paths

● Corrosion resistant

● Easy identification - All collets marked with tube

size

● Total fittings system solution

● Reduced assembly & maintenance times provide

time/labor savings

● Greater reliability and reduced testing

● Ease of tube insertion in areas of restricted

access

Typical Layout & Dimensions

Component Functions

Tube Connection / Disconnection

Installation

1. Ensure that the end of the tube
is cut square and is free from
burrs.

2. Push the tube through the collet
into the fitting.

3. Continue pushing the tube
through the ‘O’ ring until it bottoms
on the tube stop. Then pull back
on the tube to reinforce the collet
teeth gripping action.

4. To disconnect - First ensure
there is no air present. Push the
tube into the fitting until it bottoms
on the tube stop. Then hold down
the collet and withdraw the tube.

Metric, NPT Female

Tube type also
indicated on
top of page
i.e. Inch or Metric

* Similar dimensions given in
individual tables refer to the collet
being in the ‘IN’ position.

Body - The body has an internally machined form to secure the collet(s), “O” ring(s) and

Tube support(s). It also has internal & externally machined thread form(s) for
connection to ports where applicable.

Collet - The purpose of the collet is to grip the tube and ensure it is retained by the fitting

at all times.

“O” Ring - The “O” ring is to ensure adequate interference between the tube & fitting body

therefore providing a pneumatic seal at all times.

Tube Support - The tube support prevents the tube collapsing during extreme tensile loading

conditions. Such conditions are only encountered during performance testing and
far exceed those experienced during normal use.
