Frequently Asked Questions

• What tools do I need to install this fitting? Press fittings require specialized press tongs with the correct jaw type (commonly designated 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 pressing indicator (e.g. a sealing O-ring that leaks if the pressing is not completed) - before the joint is embedded in a wall or screed, a pressure test of the entire 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 this to a heating technician/plumber, especially for joints that will be embedded in a wall or screed without the possibility of later inspection.
