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 CLIPS

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. 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.

Stop ends are also useful when pressure testing a system before appliances are connected.

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 to a radiator.

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 Speedfit connection 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 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.

SERVICE VALVE

Speedfit x Speedfit

Mechanism twists out of sight

The Speedfit range of brass chromium plated service valves can be used on both hot and cold water services and central heating. Push fit connections mean much reduced installation time, especially in confined spaces.

The valves, in 10 to 22mm, have a 1/4 turn open/close mechanism operated by a screwdriver slot or a lever.

Tap connector patterns have a union nut to connect direct to a tap or floatvalve. Lever operated valves are supplied with both a blue and a red indice.

The ability of Speedfit products to twist whilst in situ allows the screwdriver slot operating valve to be turned out of sight, helping to avoid unauthorised tampering.

Manufactured to a quality you would expect from Speedfit, our range of Flexi Hoses has 40 different patterns.

Available in lengths from 150mm to 1,000mm, ends are either push fit to union nut or push fit to push fit, including hoses with an integral service valve operated by a 1/4 turn screwdriver slot.

Apart from being aesthetically pleasing the new white hoses offer more flexibility and a larger through bore for better flow characteristics.

More specialist patterns have been designed to help the installation of monobloc mixers to a 15mm supply. Sold in pairs, each hose in the pair has a different spanner location to ease connection of the threaded end into the monobloc’s inlets.

The hoses are suitable for cold water up to 10 Bar and hot water (65˚C max) up to 6 Bar and approved by WRAS.

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 the inside of the pipe, gives a secondary 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.
