Product catalog summary
Overview of Speedfit Fittings
Speedfit fittings utilize a unique grip and seal mechanism. The fittings consist of a collet with stainless steel teeth that grip the pipe and an 'O' ring that ensures a permanent, leak-proof seal. The Superseal Pipe Insert enhances this by providing a double 'O' ring seal, adding a secondary seal against the bore of the fitting and increasing the rigidity of the pipe within the fitting.
Twist and Lock Fittings
These fittings offer an additional security feature where a twist of a screwcap locks the pipe in place, increasing compression on the 'O' ring for enhanced security. The fitting should initially be in an 'unlocked' position, indicated by a gap between the screwcap and the body flange. Twisting the screwcap until it touches the body flange locks the pipe and enhances the seal.
Making a Good Connection
Ensure fittings and pipes are clean and undamaged before use. Push the pipe into the fitting up to the pipe stop. The insertion mark on the pipe should align with the collet head. The 'O' ring on the Superseal Pipe Insert provides a secondary seal, ensuring a secure connection.
Preparation and Testing
Ensure pipes are free of score marks and cut squarely. Use JG Pipe Cutters for Speedfit Barrier Pipe. Remove burrs and sharp edges to prevent 'O' ring damage. Use a Superseal or standard Speedfit Pipe Insert with Speedfit Pipe. Test the system before leaving the site or using it, following the recommended test procedure in the Technical Checklist.
Disconnection and Reuse
To disconnect, ensure the system is depressurized. Turn the screwcap back to the unlocked position. The fitting can be reused without replacement parts. Use collet covers or clips for added security against disconnection.
What Not to Do
Avoid using hacksaws to cut pipes or leaving burrs, as these can cause leaks. Do not use damaged or scored pipes. Ensure the pipe is fully inserted past the collet and 'O' ring. Do not insert fingers into the fitting to avoid injury from stainless steel teeth.
Collet Covers and Clips
Collet covers and clips provide additional security and color coding for pipes. White or grey clips prevent accidental disconnection, while red or blue clips are for color coding and should be used when the fitting is locked.
Pipe Stop Distances
Stop distances vary by pipe size: 10mm (20mm), 15mm (30mm), 22mm (35mm), and 28mm (44mm).

Making a good  connection-1

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. Grips before it seals Stainless steel teeth grip the pipe Pipe Insert gives secondary seal Main ‘O’ Ring Seal

MAKING A GOOD CONNECTION Fittings and pipe should be kept clean, bagged and undamaged before use. PREPARE THE 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 using Speedfit Pipe use a Superseal Pipe Insert or a standard Speedfit Pipe Insert. A twisting motion will aid insertion. The insert should only be used with Speedfit Pipe. TWIST AND LOCK FITTINGS The fitting should be in the ‘unlocked’ position,...

STANDARD FITTINGS Standard Speedfit connections are made in the same way as Twist and Lock. Push pipe up to stop Secondary Seal Pipe mark indicates full insertion Pull to check the connection 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. TO DISCONNECT Ensure the system is depressurised. The screwcap on Twist and Lock Fittings will need to be turned back to the unlocked position. For both Twist and Lock and Standard fittings, push the collet square against the face of the fitting by...

PIPE STOP DISTANCES Stops are located at the following distances from the end of COLLET COVERS AND COLLET CLIPS 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. White or grey collet clips are used with standard fittings to prevent accidental pipe disconnection. Red or Blue collet clips provide colour coding of pipe on Twist and Lock fittings....
