Frequently Asked Questions

• What tools do I need to install this fitting? Press fittings require specialized crimping pliers with the correct jaw type (commonly marked B, F, or TH depending on the system) matching the size and type of the fitting - without the right tool the joint cannot be made or checked.
• How do I know the joint has been crimped correctly? Quality press fittings have a crimp indicator (e.g. a sealing O-ring that leaks if the crimp was not completed) - before embedding in a wall or screed, always carry out a pressure test of the whole system.
• Can the joint be disassembled after crimping? No, unlike a screwed (compression) fitting, a crimped joint is permanent and disassembling it requires cutting out the fitting and replacing it with a new one.
• Does installation have to be carried out by a professional? Yes, crimping 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.
