FAQs
What type of pipe can I use with this fitting?
This fitting is designed for 15mm copper pipe and JG Speedfit PEX and polybutylene plastic pipes. For plastic pipes, you must use the appropriate JG Speedfit pipe inserts.
Do I need any special tools to install this fitting?
No, the Speedfit Stem Elbow is a push-fit fitting and requires no special tools for installation or demounting. A pipe cutter and de-burring tool are recommended for preparing the pipe end.
How do I ensure a secure connection?
Ensure the pipe is pushed fully and squarely into the fitting until it stops. Then, twist the plastic nut clockwise until it locks firmly in place. A secure connection is indicated by the nut being fully tightened and the fitting feeling rigid.
Can this fitting be used for central heating systems?
Yes, the John Guest Speedfit Stem Elbow is suitable for use in hot and cold water and central heating systems.
What does 'stem elbow' mean?
A stem elbow typically refers to a fitting that allows for a connection to change direction (elbow) while also having a protruding stem or spigot, often for connecting to another fitting or appliance outlet. In this case, it allows a 90-degree male-to-female crossover.
How long will the seals last?
The fittings are designed for long-term use. The main O-ring seal and the grip teeth provide a durable, reliable seal that resists wear, corrosion, and scale build-up under normal operating conditions.
Can I reuse this fitting after demounting?
Yes, Speedfit fittings are designed to be demounted and reused multiple times. Ensure the pipe end and the inside of the fitting are clean before re-installing.
Troubleshooting
Fitting is leaking after installation
Ensure the pipe was pushed fully and squarely into the fitting before locking. Check for any debris or damage on the pipe end or inside the fitting. If using plastic pipe, verify that the correct Speedfit insert was used and properly seated.
Difficulty pushing pipe into fitting
Check that the pipe end is clean, cut square, and free from damage. Ensure you are using the correct size and type of pipe compatible with the fitting. For copper pipe, ensure it is properly de-burred.
Pipe won't release when demounting
Make sure the plastic nut is fully unlocked by hand. Push the collet firmly towards the body of the fitting while simultaneously pulling the pipe. Ensure no debris is obstructing the collet mechanism.
Fitting makes a noise under pressure
Occasional slight noises can occur due to water flow. If the noise is significant or accompanied by vibration or leaks, check the pipe connection and ensure it is fully engaged and the locking nut is secured.
