Push-fit fittings FAQs
The Superseal Insert (STS) has a dual O-Ring, which provides a greater seal than a standard Insert. When combined with a Speedfit fitting, the fitting and Superseal insert form a unique multi-seal.
The Standard Insert (TSM) does not have an O-Ring and therefore allows more pipe into the fitting, making it suitable when connecting Speedfit pipe to compression fittings.
Yes, they are suitable for this application.
Yes, however, the insert should be selected based on the fitting type. If using JG Speedfit Polybutylene Layflat, or PEX pipe with JG Speedfit Twist & Lock fittings we recommend using the JG Speedfit Superseal Insert which offers a multiseal connection. If installing the pipe with standard-type JG Speedfit fittings, then a Standard Insert is required. Both inserts ensure a tight leak-proof connection.
Yes, we offer a range of replacement collets, seals and O-Rings for our push-fit plumbing fittings should it be required. This enables JG Speedfit fittings to be refurbished and re-used. However, it is important to note that when handled and used correctly, JG Speedfit fittings and pipe should not require ongoing maintenance. All systems come with a 50-year guarantee.
Speedfit fittings can be used with plastic barrier pipe or copper pipe. Speedfit cannot be used with stainless steel pipe.
No, JG Speedfit fittings and pipe must not be used on any secondary circulating hot water applications. This is due to the risk of operating temperatures fluctuating above JG Speedfit working parameters.
Yes, either a Speedfit standard or Superseal insert is required to ensure that the ends of the plastic pipe are kept nice and round, and to minimise any loss of shape which can occur when cutting the pipe.
All plastic pipes and fittings should be adequately protected within sealed ducts. JG Speedfit products along with other materials such as electrical cables may be damaged if rodents are present. If vermin infestation is suspected, then a rodent exterminator should take appropriate action to prevent structural damage or disease.
When connecting to copper pipe, the minimum distance to make a solder connection on the copper pipe inserted into a Speedfit fitting is 450mm (18 inches). To prevent damage, you must ensure any residual flux solder does not come into contact with the fitting. A pipe insert is not required when connecting Speedfit fittings to copper pipe.
Yes, but only if the pipe and fittings are compatible. Compression fittings with a short tube stop depth or brass olives should not be used with Speedfit pipes. Use a standard pipe insert (TSM) and follow the instructions of the compression fitting manufacturer when connecting to plastic pipework. The connection should not need more than 2 full turns after the olive has gripped the pipe. JG Speedfit recommends using soft copper olives, always ensure the nut and olive are in place before inserting the pipe insert.
We have been using JG Speedfit across our sites for many years and find it to be a more reliable and better quality fitting than its competitors, especially the locking feature which is secure and also easy to demount when required.
