MAKING A GOOD CONNECTION
STANDARD SPEEDFIT FITTINGS
HOW SPEEDFIT WORKS
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.

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

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.
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.

PIPE STOP DISTANCES
Stops are located at the following distances from the end
of the fitting:
size 10mm 15mm 22mm 28mm
stop distance 20mm 30mm 35mm 44mm
COLLET COVERS
Use a collet cover or collet clip to provide added security
against pipe disconnection, e.g. the fitting coming into
contact with rigid surfaces and behind dry-lining walls.
Collet covers for use with standard Speedfit fittings, are
available in white or in red or blue to allow colour coding of pipes.
Collet cover
STOP END
The unique feature of the
Speedfit Concept, the ability
to disconnect the fitting
should you want to, means
the Speedfit Stop End not
only provides a permanent
leakproof seal, but can be
readily removed to allow
work to restart or to allow
an extension to a system.
Stop end
Stop ends are also useful when pressure testing a system
before appliances are connected.
Thus, the fitting is especially
useful to allow water to be
turned back on, overnight for
instance, or if a job has to be
interrupted for another reason.
STEM ELBOW
Designed to simplify pipe connection
in restricted spaces. The Speedfit
Stem Elbow provides an instant swivel
fitting so pipe can be orientated in
any direction.
A special 10mm version gives a neat
connection from concealed plumbing

TAP CONNECTORS
Speedfit manufacturer a wide range of connectors
including conventional straight and bent tap connectors.
The range also offers a special and
unique Tap Connector that only
requires a simple hand tightening to
connect up a terminal tap, mixer or
float valve. An integral seal within the
fitting avoids the need for further
sealant. The connectors are useful
when replacing existing brassware or
in other confined spaces.
Coupling up to a supply is easy. The
pipe is simply pushed home into
the Sp eedfit con nection and is
instantly secured, without the need
for specialist tools.
FLEXI HOSES
SPEEDFIT MANIFOLD
Speedfit have introduced an innovative 22mm x 10mm 4
way manifold. Departing from the usual manifold design,
this new product has 4 in-line 10mm outlets, offering a
neater envelope size and therefore a much smaller
installation space.
Other benefits include better flow characteristics and a
more even distribution of hot water.
The 22mm and 10mm Speedfit push-fit connections make
for a fast and easy installation, even in confined spaces.
Whilst designed as a heating product, the manifold can
also be used in a mains pressure hot or cold domestic
plumbing system, to feed bathroom or kitchen taps and
mixers. This allows for a more efficient installation as
every terminal fitting has its own dedicated supply.
APPLIANCE TAP
The Speedfit range includes an Appliance Tap for
the permanent connection of washing machines and
dishwashers, thus enabling complete water isolation to
the appliance.
COLLET CLIPS
Collet clip
Collet clips are available in grey and white for use with
standard fittings to prevent accidental pipe
disconnection.
Red or blue collet clips provide colour coding of pipe on
twist and lock fittings.
They are not designed to prevent accidental release and
should be fitted when the fitting is in the locked position.
RELEASE AID
The action of pressure in a system could increase the grip
of the collet. The release aid allows a firmer grip on the
collet whilst removing the pipe.

A simple push fit connection of the supply pipe and a
plastic thread on the outlet to marry well with the plastic
thread on the hose means the Speedfit Appliance Tap is very
easy to install. The large round handle is easy to grip and turn.
SUPERSEAL PIPE INSERT
The Superseal Pipe Insert has been developed to be used
with Speedfit Barrier Pipe and Speedfit Fittings to provide
an extra line of defence when installing a Speedfit Push
Fit System.
The insert has it’s own ‘O’ ring which, with a stem sliding
within th e inside of th e pipe, give s a secondar y seal
against the inside of the fitting.
The Speedfit Connection, when made with the insert, has
a number of design features.
Sliding the stem of the insert into the pipe gives greater
compression of the main ‘O’ ring on the pipe and greater
rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.
A connection is easier to make because the head of the
insert has been designed for ease of insertion.
Superseal Inserts are listed on page 14.
