Do you have to put inserts with Speedfit fittings?
Do I need to use an insert every time I connect Speedfit pipes to a fitting, and why are there two types of insert? The simple answer is yes, always use an insert when installing Speedfit pipes as it supports the shape of the pipe. (Only TSM inserts should be used with compression fittings).
Can you use plastic push fit on copper?
Push fit fittings can be used on copper or plastic pipe but not chrome plated pipe as the grip rings in the fittings are not strong enough to grip the chrome. Different makes of plastic pipe have different pipe inserts, you must ensure you use the correct ones for the pipe that you are using.
Can you bend Speedfit Pipe?
It is also possible to bend Speedfit Pipe using a standard pipe bender. The pipe should not be heated with a blowlamp or hot air gun. For bends of radii smaller than those shown, standard elbow fittings are recommended. There are two types of pipe clip in the Speedfit Range.
Is speedfit better than copper?
Speedfit is fine, the flow rates are good in plastic, better than copper size for size. If you are worried about flow look closely at the taps and valves you will be using.
Can you bend barrier pipe?
You can make bends in barrier pipe without ‘cold forming bends’, but it is best to clip it as soon as it is straight and them another clip a few inches along. (4 clips per bend.) This ensures that the bend holds its shape and doesn’t exert pressure on the adjacent fitting. It is also cheaper than cold forming bends.
What’s the minimum distance to connect a Speedfit fitting?
Connection to copper pipe 450mm is the minimum distance to make a solder connection on copper pipe inserted into a Speedfit fitting. Ensure that any residual flux solder does not come into contact with the fitting.
What’s the distance between a boiler and a Speedfit fitting?
Use of collet covers or collet clips on fittings recommended. Connection To Boilers A minimum 1000mm run of copper pipe must be installed between the boiler and the Speedfit system, as per BS5955: Part 8. Connection to copper pipe 450mm is the minimum distance to make a solder connection on copper pipe inserted into a Speedfit fitting.
Do you need to use insert when installing Speedfit?
Do I need to use an insert every time I connect Speedfit pipes to a fitting, and why are there two types of insert? The simple answer is yes, always use an insert when installing Speedfit pipes as it supports the shape of the pipe.
Why do I need a TSM insert for Speedfit?
The ‘ STS has an extra O-Ring, which helps to reduce the risk of leaks due to side load. The ‘TSM’ insert does not have an O-Ring, and therefore allow more pipe into the fitting. This is important when using Speedfit pipe with compression fittings as use of a TSM insert allows the olive to sit further down the pipe.
Do you use a pipe insert when connecting Speedfit pipe?
Always use a Pipe Insert when connecting Speedfit Pipe. The insert provides greater rigidity of the pipe within the fitting and ensures the pipe is completely round to make for a better seal between the KOL ring and the outside diameter of the pipe.
What’s the best way to test a Speedfit connection?
Our recommended test procedure is shown in our Technical Checklist. Twist the screwcap until it touches the body flange. This locks the pipe into position and increases the ‘O’ ring seal around the pipe for greater security. Standard Speedfit connections are made in the same way as Twist and Lock. Pull to check the connection is secure.
Which is the unlocked position on a Speedfit pipe?
The fitting should be in the ‘unlocked’ position, this is shown by a small gap between the screwcap and the body flange. Push the pipe 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.
Can you use a TSM insert on Speedfit PB?
Yes, but only if they are compatible. Compression fittings with a short tube stop depth should not be used. Use a ‘TSM’ insert and follow the instructions of the compression fitting manufacturer when connecting to plastic pipework. 5. What is the difference between Speedfit PB (Polybutylene) and Speedfit PEX pipe?
