Frequently Asked Questions

• What tools do I need to install this fitting? Press fittings require specialized pressing pliers with the correct jaw type (commonly labeled B, F, or TH depending on the system) matching the fitting's size and type - without the right tool, the joint cannot be made or checked.
• How do I know the joint has been pressed correctly? Quality press fittings have a press indicator (e.g. a sealing O-ring that leaks if the press is incomplete) - before embedding in a wall or screed, a pressure test of the entire system must always be carried out.
• Can a pressed joint be taken apart afterwards? No, unlike a screwed (compression) connection, a pressed joint is permanent, and taking it apart requires cutting out the fitting and replacing it with a new one.
• Must installation be carried out by a professional? Yes, pressing fittings requires professional skill and correctly calibrated tools - we recommend entrusting it to a heating engineer/plumber, especially for joints that will be embedded in a wall or screed without the possibility of later inspection.
