Frequently Asked Questions

• What tools do I need to install this fitting? Press fittings require specialized press pliers with the correct jaw type (commonly labeled B, F, or TH depending on the system) matching the size and type of the fitting - without the proper 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 entire system should always be performed.
• Can the joint be disassembled after pressing? No, unlike a screwed (compression) fitting, a pressed joint is permanent and removing it 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 leaving it to a heating engineer/plumber, especially for joints that will be embedded in a wall or screed without the possibility of later inspection.
