Frequently Asked Questions

• What tools do I need to install this fitting? Press fittings require specialized press pliers with the correct type of jaw (commonly marked B, F, or TH depending on the system) corresponding to the size and type of the fitting - without the right tool, the joint cannot be made or checked.
• How do I know the joint is properly pressed? Quality press fittings have a press indicator (e.g. a sealing O-ring that leaks if the pressing is incomplete) - before embedding in a wall or screed, a pressure test of the whole system must always be carried out.
• Can the joint be disassembled after pressing? No, unlike a screwed (compression) fitting, a pressed joint is permanent and disassembling it 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 entrusting the work to a heating engineer/plumber, especially for joints that will be embedded in a wall or screed without the possibility of later inspection.
