HOW SPEEDFIT WORKS
Grips before it seals
Main ʻOʼ Ring Seal
Stainless steel teeth
grip the pipe
Pipe insert gives
secondary seal
Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless
steel teeth to grip the pipe and an ‘O’ ring to provide a permanent leak proof seal.
Use of the
Superseal Pipe Insert
ensures a double ‘O’ ring seal.
An ‘O’ ring at the head of the insert and the shape of the stem, provide a secondary seal against
the bore of the fitting. A combination of this and the main ‘O’ ring ensure a good connection.
The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.
The head of the insert has been designed for ease of insertion.
The additional benefit of Twist and Lock Fittings is that a twist of a screwcap locks the pipe in
position and gives increased compression on the ‘O’ ring for even greater security.
MAKING A GOOD CONNECTION
Pipe Cutter
JG TS
Speedfit
Barrier Pipe
Ensure the pipe is free of score
marks. Cut the pipe square.
When using Speedfit Barrier Pipe
cut along an insertion mark. We
recommend the use of JG Pipe
Cutters.
To prevent damage to the ‘O’ ring
remove all burrs and sharp edges.
When connecting Speedfit Pipe
use a Superseal Pipe Insert. A
twisting motion will aid insertion.
The insert should only be used
with Speedfit Pipe.
Fittings and pipe should be kept clean bagged and undamaged
before use.
NEW TWIST AND LOCK FITTINGS
The fitting should be in the ‘unlocked’ position, this is
shown with a small gap between the screwcap and the
body flange.
Push the pipe fully into the fitting, up to the pipe stop. If
the Speedfit Pipe has been cut correctly the insertion
mark on the pipe will be level with the collet head. The ‘O’
ring on the Superseal Pipe Insert provides a secondary
seal against the bore of the fitting.
A good connection
has been made.
Gap between Cap
and Flange
Pipe mark indicates
full insertion
Twist the screwcap until it
touches the body flange.
This increases the ‘O’ ring
seal around the pipe and
locks the pipe into position.
If you are not using collet
clips, ensure that the
screwcaps are in the
locked position.
Pull to check it is secure. It is good practice to test the system
prior to leaving the site or before use. Our recommended
test procedure is shown in our Technical Checklist.
ADDED BENEFIT TWIST AND LOCK
STANDARD SPEEDFIT FITTINGS
Standard Speedfit connections are made in the same way
as Twist and Lock.
Push Pipe up to Pipe Stop. If the Speedfit Pipe has been
cut correctly the insertion mark on the pipe will be level
with the collet head.
Push pipe up to stop
Secondary Seal
Pipe mark indicates
full insertion.
Pull to check connection
is secure and test the
system. Our recommended
test procedure is shown
in our Technical Checklist
on page 29.
TO DISCONNECT
Ensure that the system
is depressurised.
The screwcap on Twist
and Lock Fittings will
need to be turned back
to the unlocked position.
WHAT
NOT
TO DO
Fitting may be gripped but not
sealed if pipe is not fully inserted.
Don’t use hacksaws to cut the
pipe or leave burrs on the end of
the pipe.
Do not insert fingers into the fitting as the stainless steel
teeth may cause injury.
Remember to pressure test the completed installation
according to the recommendations in our Technical Checklist.

PREPARE THE PIPE
05
06
Push the collet square against the face of the fitting by
using fingers or with the help of our collet release tool.
With the collet held in position the pipe can be removed.
The fitting can be used again without the need for
replacement parts.
Don’t forget to push the
pipe fully into the fitting,
past both the collet (gripper)
and the ‘O’ ring.
