Frequently asked questions

• What tools do I need to install this fitting? Press fittings require specialised crimping pliers with the correct jaw type (usually marked B, F or TH depending on the system) matching the size and type of fitting - without the correct 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 pressing is incomplete) - before embedding in a wall or screed, a pressure test of the whole system is always necessary.
• Can the joint be taken apart after pressing? No, unlike a screwed (compression) union, a pressed joint is permanent, and taking it apart requires cutting out the fitting and replacing it with a new one.
• Must the installation be carried out by a professional? Yes, pressing fittings requires professional skill and correctly calibrated tools - we recommend leaving it to a heating engineer/plumber, especially for joints that will be embedded in a wall or screed with no possibility of later inspection.
