Frequently asked questions

• What tools do I need to install this fitting? Press fittings require specialised crimping pliers with the correct jaw type (commonly labelled 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 crimp indicator (e.g. a sealing O-ring that leaks if the crimp is incomplete) - always carry out a pressure test of the whole system before it is embedded in a wall or screed.
• Can the joint be taken apart after pressing? No, unlike a screwed (compression) union, a pressed joint is permanent and taking it apart means cutting out the fitting and replacing it with a new one.
• Must installation be done by a professional? Yes, crimping fittings requires skill and correctly calibrated tools - we recommend leaving it to a heating technician/plumber, especially for joints that will be embedded in a wall or screed with no possibility of later inspection.
