John Guest Drinks Tube Insert

Designed to provide internal support to pipework when used with push-fit fittings. Installed at the end of the tube, the insert reinforces the pipe wall and helps maintain a perfectly round profile, ensuring a secure and reliable seal within the fitting. When tubing is cut, the end can sometimes lose its shape slightly or become compressed when inserted into a fitting. Tube inserts prevent this by reinforcing the pipe internally, helping the collet grip and O-ring seal perform correctly. This improves connection integrity and reduces the risk of leaks or movement under load.

They are particularly important in systems where pipework may experience side loads, temperature changes or pressure fluctuations. By strengthening the pipe end, inserts help maintain the correct geometry of the connection and improve long-term reliability. Tube inserts are commonly used in potable water systems, central heating installations, and drinks dispense pipework. In beer and beverage systems, they help maintain stable connections between tubing and push-fit fittings, supporting consistent performance in busy commercial environments.

• Internal pipe support: Reinforces the tubing end for stronger push-fit connections.
• Improved sealing: Helps maintain correct tube shape for reliable O-ring sealing.
• Prevents pipe distortion: Keeps cut tube ends round and structurally stable.
• Handles side loads: Adds rigidity where pipework may experience movement.
• Versatile applications: Suitable for potable water, hot water and beverage systems.
• Compatible with plastic or soft metal tubing: Works with common push-fit pipe materials.
